|
||||
### Methodological Assessment
|
||||
|
||||
**Data Collection Methodology:**
|
||||
|
||||
**Sampling Design:**
|
||||
- **Method:** Mix - Census (vital registration), Probability samples (household surveys), Administrative records (disease surveillance)
|
||||
- **Sample Size:** Varies by indicator and country; household surveys typically n=5,000-30,000 per country
|
||||
- **Sampling Frame:** WHO collaborates with national statistical offices; frames vary by country
|
||||
- **Stratification:** Multi-stage stratified sampling for household surveys
|
||||
- **Weighting:** Post-stratification weights applied to match population demographics
|
||||
|
||||
**Data Collection Instruments:**
|
||||
- **Instrument Type:** Standardized survey questionnaires (DHS, MICS), vital registration systems, disease surveillance forms
|
||||
- **Validation:** WHO-validated instruments; pilot tested in multiple countries
|
||||
- **Question Wording:** Standardized across countries to enable comparability
|
||||
- **Mode:** Varies - in-person interviews (surveys), administrative reporting (disease surveillance), civil registration (vital statistics)
|
||||
|
||||
**Quality Control Procedures:**
|
||||
- **Field Supervision:** National statistical offices conduct field supervision; WHO provides technical support
|
||||
- **Validation Rules:** Automated validation checks for biological plausibility, consistency
|
||||
- **Consistency Checks:** Cross-indicator validation (e.g., total deaths ≥ cause-specific deaths)
|
||||
- **Verification:** WHO country offices verify data with national counterparts before publication
|
||||
- **Outlier Treatment:** Flagged for review; extreme outliers confirmed or corrected
|
||||
|
||||
**Error Characteristics:**
|
||||
- **Sampling Error:** Confidence intervals provided for survey-based estimates
|
||||
- **Non-sampling Error:** Known issues with vital registration completeness in some countries (under-registration); measurement error in self-reported data
|
||||
- **Known Biases:** Survival bias in surveys (miss mortality events); reporting bias (stigmatized conditions under-reported); coverage bias (conflict zones, hard-to-reach populations)
|
||||
- **Accuracy Bounds:** Uncertainty intervals provided for modeled estimates; typically ±10-20% for direct measurements, wider for modeled estimates
|
||||
|
||||
**Methodology Documentation:**
|
||||
- **Transparency Level:** 4/5 (Comprehensive)
|
||||
- **Documentation URL:** https://www.who.int/data/gho/info/gho-odata-api-metadata-methods
|
||||
- **Peer Review Status:** Methods reviewed by Scientific and Technical Advisory Groups; published in peer-reviewed journals (e.g., Lancet series)
|
||||
- **Reproducibility:** Code and documentation provided for modeled estimates; direct survey data reproducible through DHS/MICS archives
|
||||
|
||||
### Currency Assessment
|
||||
|
||||
**Update Characteristics:**
|
||||
- **Update Frequency:** Continuous API updates; major data releases quarterly
|
||||
- **Update Reliability:** Consistent quarterly schedule
|
||||
- **Update Notification:** Email notifications available; RSS feed; API versioning
|
||||
- **Last Updated:** 2025-01-15 (Q1 2025 data release)
|
||||
|
||||
**Timeliness:**
|
||||
- **Collection to Publication Lag:**
|
||||
- Disease surveillance: 1-3 months
|
||||
- Vital statistics: 6-18 months (varies by country)
|
||||
- Survey data: 12-24 months
|
||||
- Modeled estimates: Annual updates each January
|
||||
- **Factors Affecting Timeliness:** National reporting schedules, data quality review, modeling cycles
|
||||
- **Historical Timeliness:** Generally consistent; COVID-19 pandemic caused some delays in 2020-2021
|
||||
|
||||
**Currency for Different Uses:**
|
||||
- **Real-time Analysis:** Unsuitable - significant lag
|
||||
- **Recent Trends:** Suitable for annual trends; unsuitable for sub-annual trends
|
||||
- **Historical Research:** Excellent - consistent time series back to 1990 for most indicators
|
||||
|
||||
### Objectivity Assessment
|
||||
|
||||
**Potential Biases:**
|
||||
|
||||
**Political Bias:**
|
||||
- **Government Influence:** Member states report their own data, creating potential for selective reporting or underreporting of sensitive issues (e.g., HIV, maternal mortality in conservative countries)
|
||||
- **Editorial Stance:** WHO maintains scientific neutrality; data published regardless of political sensitivities
|
||||
- **Political Pressure:** Rare instances of countries disputing WHO estimates (e.g., MMR, under-5 mortality); WHO publishes both reported and estimated figures
|
||||
|
||||
**Commercial Bias:**
|
||||
- **Funding Sources:** Pharmaceutical industry contributes to WHO voluntary funds; potential for influence on health priority setting
|
||||
- **Advertising Influence:** Not applicable (non-commercial)
|
||||
- **Proprietary Interests:** None
|
||||
|
||||
**Cultural/Social Bias:**
|
||||
- **Geographic Bias:** Better data quality in high-income countries with strong vital registration; estimation models fill gaps but introduce uncertainty
|
||||
- **Social Perspective:** Medical/epidemiological perspective; less representation of social determinants, traditional medicine
|
||||
- **Language Bias:** English primary language; some resources in French, Spanish; limited translation
|
||||
- **Selection Bias:** Indicators prioritized based on global health priorities (SDGs, WHO programs); some regional health issues underrepresented
|
||||
|
||||
**Transparency:**
|
||||
- **Bias Disclosure:** WHO acknowledges data quality limitations by country; uncertainty intervals provided
|
||||
- **Limitations Stated:** Comprehensive - each indicator has detailed metadata noting limitations
|
||||
- **Raw Data Available:** Some raw data available through member states; WHO publishes processed/aggregated data
|
||||
|
||||
### Reliability Assessment
|
||||
|
||||
**Consistency:**
|
||||
- **Internal Consistency:** Validation rules ensure mathematical consistency (e.g., age-specific rates sum to total)
|
||||
- **Temporal Consistency:** Generally stable; definitional changes clearly marked (e.g., ICD version transitions)
|
||||
- **Cross-source Consistency:** Good agreement with World Bank, UNICEF for shared indicators; differences documented
|
||||
|
||||
**Stability:**
|
||||
- **Definition Changes:** Occasional - major changes coincide with ICD revisions (10-15 year cycles)
|
||||
- **Methodology Changes:** Modeling methods updated periodically (documented in methods papers)
|
||||
- **Series Breaks:** Clearly marked when definitions or methods change materially
|
||||
|
||||
**Verification:**
|
||||
- **Independent Verification:** IHME Global Burden of Disease provides independent estimates; generally corroborate WHO within uncertainty bounds
|
||||
- **Replication Studies:** Academic researchers use WHO data extensively; errors/discrepancies reported and corrected
|
||||
- **Audit Results:** External auditor reviews WHO financial processes annually; no data quality audit per se
|
||||
|
||||
### Accuracy Assessment
|
||||
|
||||
**Validation Evidence:**
|
||||
- **Benchmark Comparisons:** For countries with high-quality vital registration, WHO data matches national data closely (typically <5% difference)
|
||||
- **Coverage Assessments:** Vital registration completeness assessed; ranges from >95% in high-income countries to <50% in some low-income countries
|
||||
- **Error Studies:** WHO conducts periodic data quality assessments; publishes reports on data quality scores by country
|
||||
|
||||
**Accuracy for Different Uses:**
|
||||
- **Point Estimates:** Reliable for countries with good vital registration (uncertainty ±5-10%); moderate reliability for modeled estimates (uncertainty ±15-30%)
|
||||
- **Trend Analysis:** Reliable for detecting medium-term trends (5+ years); less reliable for year-to-year changes
|
||||
- **Cross-sectional Comparison:** Reliable for broad comparisons; caution needed for fine distinctions (rank ordering sensitive to uncertainty)
|
||||
- **Sub-population Analysis:** Limited - most data national-level aggregates; some sex/age disaggregation but limited socioeconomic, geographic, ethnic disaggregation
|
||||

## Known Limitations and Caveats
|
||||
|
||||
### Coverage Limitations
|
||||
|
||||
**Geographic Gaps:**
|
||||
- Small territories not covered: Some Pacific islands, Caribbean territories
|
||||
- Conflict zones: Syria, Yemen, Somalia have data gaps 2011-present
|
||||
- Closed countries: North Korea data limited, based on external estimates
|
||||
|
||||
**Temporal Gaps:**
|
||||
- Historical data limited pre-1990 for many indicators
|
||||
- Country-specific gaps due to civil conflicts, natural disasters
|
||||
- Survey data gaps (e.g., countries may conduct household surveys every 3-5 years, leaving inter-survey gaps)
|
||||
|
||||
**Population Exclusions:**
|
||||
- Homeless populations often excluded from surveys
|
||||
- Institutionalized populations (prisons, nursing homes) variably included
|
||||
- Nomadic populations challenging to enumerate
|
||||
- Refugees/IDPs may not be fully captured in national statistics
|
||||
|
||||
**Variable Gaps:**
|
||||
- Mental health indicators limited (stigma, measurement challenges)
|
||||
- Rare diseases underrepresented
|
||||
- Traditional medicine not systematically captured
|
||||
- Social determinants of health (education, income, housing) limited in health-specific datasets
|
||||
|
||||
### Methodological Limitations
|
||||
|
||||
**Sampling Limitations:**
|
||||
- Household surveys miss mortality events (dead people can't be surveyed - survival bias)
|
||||
- Non-response bias in surveys (refusals, hard-to-reach populations)
|
||||
- Small sample sizes for sub-populations (rare diseases, small countries)
|
||||
|
||||
**Measurement Limitations:**
|
||||
- Self-reported health status subject to recall bias, social desirability bias
|
||||
- Cause of death from verbal autopsy (in countries without medical certification) less accurate than medical certification
|
||||
- Diagnostic heterogeneity across countries (differences in healthcare access, diagnostic criteria)
|
||||
|
||||
**Processing Limitations:**
|
||||
- Missing data imputed using statistical models (introduces uncertainty)
|
||||
- Age standardization uses standard population (masks age-structure differences)
|
||||
- Aggregation to national level masks within-country inequalities
|
||||
|
||||
### Comparability Limitations
|
||||
|
||||
**Cross-national Comparability:**
|
||||
- Definitional differences despite standardization efforts (e.g., "live birth" varies)
|
||||
- Data quality varies (high-quality vital registration vs. modeled estimates)
|
||||
- Healthcare access affects diagnostic rates (more healthcare → higher reported prevalence)
|
||||
- Cultural factors affect reporting (stigmatized conditions underreported variably)
|
||||
|
||||
**Temporal Comparability:**
|
||||
- ICD version changes create series breaks (ICD-9 → ICD-10 → ICD-11)
|
||||
- Survey questionnaire changes over time
|
||||
- Diagnostic technology improvements affect disease detection rates (e.g., better cancer detection increases apparent incidence)
|
||||
|
||||
**Sub-group Comparability:**
|
||||
- Small sample sizes for sub-populations result in suppression or wide confidence intervals
|
||||
- Intersectional analysis limited (e.g., sex × age × income often not available)
|
||||
|
||||
### Usage Caveats
|
||||
|
||||
**Inappropriate Uses:**
|
||||
1. **DO NOT use for real-time outbreak detection** - use disease surveillance systems instead (lag too long)
|
||||
2. **DO NOT use for within-country analysis** - national aggregates mask subnational variation; use national statistics
|
||||
3. **DO NOT compare fine ranks** - uncertainty intervals overlap; statistically significant differences only
|
||||
4. **DO NOT infer causation** - cross-sectional/ecological data; appropriate for hypothesis generation, not causal inference
|
||||
|
||||
**Ecological Fallacy Risks:**
|
||||
- National-level associations don't necessarily hold at individual level
|
||||
- Example: Countries with higher healthcare spending may have higher disease prevalence (better detection) - doesn't mean spending causes disease
|
||||
|
||||
**Correlation vs. Causation:**
|
||||
- Data appropriate for descriptive epidemiology (who, what, where, when)
|
||||
- Analytical epidemiology (why) requires individual-level data, longitudinal designs, causal inference methods not supported by these aggregated data
|
||||

||||
## Recommended Use Cases
|
||||
|
||||
### Ideal Applications
|
||||
|
||||
**Research Questions Well-Suited:**
|
||||
1. "How has global life expectancy changed over the past 30 years?"
|
||||
2. "Which countries have the highest burden of cardiovascular disease?"
|
||||
3. "Is there a relationship between health expenditure and health outcomes across countries?"
|
||||
4. "How do regions compare on progress toward SDG health targets?"
|
||||
|
||||
**Analysis Types Supported:**
|
||||
- Descriptive statistics (means, medians, percentiles by country/region/income group)
|
||||
- Trend analysis (time series over years)
|
||||
- Cross-sectional comparison (countries, regions, income groups)
|
||||
- Correlation analysis (relationships between indicators - ecological level)
|
||||
- Policy evaluation (before/after national policy implementation - country time series)
|
||||
|
||||
### Appropriate Contexts
|
||||
|
||||
**Geographic Contexts:**
|
||||
- Global comparisons (all 194 countries)
|
||||
- WHO regional comparisons (6 regions)
|
||||
- Income group comparisons (World Bank income classifications)
|
||||
- Individual country trend analysis
|
||||
|
||||
**Temporal Contexts:**
|
||||
- Long-term trends (1990-present) for most indicators
|
||||
- Medium-term trends (5-10 years) most reliable
|
||||
- Historical research (especially post-MDG era 2000+)
|
||||
|
||||
**Subject Contexts:**
|
||||
- Health outcomes (mortality, morbidity, life expectancy)
|
||||
- Health systems (coverage, capacity, financing)
|
||||
- Health risks (tobacco, alcohol, environmental)
|
||||
- Disease burden (DALYs, YLL, YLD)
|
||||
- SDG health monitoring
|
||||
|
||||
### Use Warnings
|
||||
|
||||
**Avoid Using This Source For:**
|
||||
1. **Subnational analysis** → Use national statistical office data instead
|
||||
2. **Real-time disease surveillance** → Use WHO Disease Outbreak News, national surveillance systems
|
||||
3. **Individual-level research** → Use microdata from DHS, MICS, national health surveys
|
||||
4. **Rare diseases** → Use disease-specific registries, clinical databases
|
||||
5. **Recent data (<1 year old)** → Use national sources (lower latency)
|
||||
|
||||
**Recommended Alternatives For:**
|
||||
- Subnational data → National statistical offices, DHS/MICS (subnational estimates)
|
||||
- More timely data → National health ministries, Eurostat, OECD (for member countries)
|
||||
- Individual-level analysis → DHS, MICS, NHANES, national health surveys (microdata)
|
||||
- Detailed disease burden → IHME Global Burden of Disease (more detailed)
|
||||
- Health expenditure detail → OECD Health Statistics (for OECD countries)

## Cataloger Notes
|
||||
|
||||
**Internal Notes:**
|
||||
- Excellent source; high authority; essential for Substrate health domain
|
||||
- API well-documented and stable
|
||||
- Consider adding more recent subnational sources to complement national-level GHO data
|
||||
- Monitor ICD-11 transition (expected 2025-2027) - may affect time series comparability
|
||||
|
||||
**To Do:**
|
||||
- [ ] Add related organizations (GAVI, Global Fund, UNITAID)
|
||||
- [ ] Cross-reference with relevant Problems and Solutions
|
||||
- [ ] Create update script for quarterly data refreshes
|
||||
|
||||
**Questions for Review:**
|
||||
- Should we catalog individual indicators separately or keep as single source entry?
|
||||
- How to handle ICD-11 transition in cataloging (new source entry vs. version update)?

|
||||
## Known Limitations and Caveats
|
||||
|
||||
### Coverage Limitations
|
||||
|
||||
**Geographic Gaps:**
|
||||
- Small island states often have incomplete data
|
||||
- Conflict zones (Syria, Yemen, South Sudan) - significant gaps
|
||||
- Non-UN members (Taiwan, Kosovo) not included
|
||||
|
||||
**Temporal Gaps:**
|
||||
- Tier 3 indicators have short time series (<5 years)
|
||||
- Pandemic disrupted data collection (2020-2021 gaps)
|
||||
- Historical baseline data limited (pre-2015)
|
||||
|
||||
**Population Exclusions:**
|
||||
- Refugees/IDPs variably counted
|
||||
- Homeless populations often excluded
|
||||
- Indigenous peoples sometimes undercounted
|
||||
|
||||
**Variable Gaps:**
|
||||
- Tier 3 indicators (30+ indicators) still lack established methodology
|
||||
- Disaggregation limited (sex/age available, but income/disability often not)
|
||||
- Environmental indicators have quality issues in many countries
|
||||
|
||||
### Methodological Limitations
|
||||
|
||||
**Sampling Limitations:**
|
||||
- Household surveys miss institutionalized populations
|
||||
- Small countries use census rather than sample (no sampling error estimates)
|
||||
- Non-response bias in surveys
|
||||
|
||||
**Measurement Limitations:**
|
||||
- Self-reported data subject to bias
|
||||
- Administrative data completeness varies
|
||||
- Proxy indicators used when direct measurement infeasible
|
||||
|
||||
**Processing Limitations:**
|
||||
- Gap-filling models introduce uncertainty
|
||||
- Harmonization adjustments may not fully account for definitional differences
|
||||
- Aggregation masks within-country inequality
|
||||
|
||||
### Comparability Limitations
|
||||
|
||||
**Cross-national Comparability:**
|
||||
- Definitional differences despite harmonization
|
||||
- Data quality varies dramatically (high-income vs. low-income)
|
||||
- Collection methods differ (surveys, censuses, admin records)
|
||||
|
||||
**Temporal Comparability:**
|
||||
- Methodology changes for Tier 3 indicators
|
||||
- Survey instruments updated over time
|
||||
- New data sources introduced
|
||||
|
||||
---
|
||||
|
||||
## Recommended Use Cases
|
||||
|
||||
### Ideal Applications
|
||||
|
||||
**Research Questions Well-Suited:**
|
||||
1. "How is the world progressing toward ending extreme poverty (SDG 1)?"
|
||||
2. "Which countries are on track to meet SDG targets by 2030?"
|
||||
3. "What is the relationship between education (SDG 4) and health (SDG 3) outcomes?"
|
||||
4. "How has climate action (SDG 13) progressed since 2015?"
|
||||
|
||||
**Analysis Types Supported:**
|
||||
- Descriptive statistics (global/regional progress)
|
||||
- Trend analysis (SDG indicator trajectories)
|
||||
- Cross-country comparison (leader/laggard identification)
|
||||
- Correlation analysis (inter-SDG relationships)
|
||||
- Gap analysis (target vs. actual)
|
||||
|
||||
### Use Warnings
|
||||
|
||||
**Avoid Using This Source For:**
|
||||
1. **Real-time monitoring** → Use national dashboards, specialized systems
|
||||
2. **Subnational analysis** → Use national statistical offices
|
||||
3. **Microdata analysis** → Use household survey microdata (DHS, MICS)
|
||||
4. **Causal inference** → Use experimental/quasi-experimental designs
|
||||
5. **Forecasting beyond 2030** → Indicators designed for 2030 endpoint

## Usage Instructions
|
||||
|
||||
### Setup
|
||||
1. Get free FRED API key: https://fred.stlouisfed.org/docs/api/api_key.html
|
||||
2. Set environment variable:
|
||||
```bash
|
||||
export FRED_API_KEY="your_api_key_here"
|
||||
```
|
||||
|
||||
### Run Update
|
||||
```bash
|
||||
cd "/Users/daniel/Library/Mobile Documents/com~apple~CloudDocs/Projects/Substrate/Data-Sources/DS-00004—FRED_Economic_Wellbeing/"
|
||||
./update.ts
|
||||
```
|
||||
|
||||
### Expected Output
|
||||
- `data/latest.json` - Raw API data (all series with full observation history)
|
||||
- `data/latest.txt` - Pipe-delimited format for Substrate
|
||||
- `update.log` - Execution log
|
||||
- `source.md` - Updated timestamps
|
||||
|
||||
### Update Frequency Recommendations
|
||||
- **Weekly:** Captures high-frequency indicators (Financial Stress, Mortgage Rates)
|
||||
- **Monthly:** Sufficient for most indicators (Unemployment, Consumer Sentiment)
|
||||
- **Quarterly:** Minimum for quarterly indicators (Debt Service, Home Prices)
|
||||
|
||||

|
||||
|
||||
## Test Results
|
||||
|
||||
### ✅ Syntax Validation
|
||||
```bash
|
||||
bun run --dry-run update.ts
|
||||
```
|
||||
**Result:** ✅ Script runs, properly detects missing API key with helpful error message
|
||||
|
||||
### ✅ File Permissions
|
||||
```bash
|
||||
ls -l update.ts
|
||||
```
|
||||
**Result:** ✅ `-rwxr-xr-x` (executable)

# FRED Economic Wellbeing Data Directory
|
||||
|
||||
This directory contains data files generated by the update.ts script.
|
||||
|
||||
## Files
|
||||
|
||||
- **latest.json** - Raw JSON data from FRED API (all indicators with full observation history)
|
||||
- **latest.txt** - Transformed pipe-delimited format for Substrate (all observations)
|
||||
- **update.log** - Update script execution log (if present)
|
||||
|
||||
## Update Process
|
||||
|
||||
Run the update script from the parent directory:
|
||||
|
||||
```bash
|
||||
# Set your FRED API key (get free key at https://fred.stlouisfed.org/docs/api/api_key.html)
|
||||
export FRED_API_KEY="your_api_key_here"
|
||||
|
||||
# Run update script
|
||||
./update.ts
|
||||
```
|
||||
|
||||
## Data Freshness
|
||||
|
||||
Different indicators have different update frequencies:
|
||||
- **Weekly:** Financial Stress Index (STLFSI4), 30-Year Mortgage Rate (MORTGAGE30US)
|
||||
- **Monthly:** Consumer Sentiment (UMCSENT), Unemployment indicators, Personal Saving Rate (PSAVERT)
|
||||
- **Quarterly:** Debt Service Ratio (TDSP), Credit Card Delinquency (DRCCLACBS), Median Home Price (MSPUS)
|
||||
- **Annual:** GINI Income Inequality Index (SIPOVGINIUSA)
|
||||
|
||||
Run weekly updates to capture high-frequency indicators; monthly updates sufficient for most indicators.

## Source Evaluation Narrative
|
||||
|
||||
### Methodological Assessment
|
||||
|
||||
**Data Collection Methodology:**
|
||||
|
||||
**Sampling Design:**
|
||||
- **Method:** FRED aggregates data from source agencies; methodologies vary by source
|
||||
- BLS labor data: Probability samples (Current Population Survey ~60,000 households; Current Employment Statistics ~145,000 businesses)
|
||||
- Financial data: Complete market data (mortgage rates, interest rates)
|
||||
- Federal Reserve data: Administrative records (debt service ratios from Flow of Funds)
|
||||
- **Sample Size:** Varies by source; CPS ~60,000 households; CES ~145,000 establishments
|
||||
- **Sampling Frame:** BLS uses Master Address File; employment surveys use BLS establishment database
|
||||
- **Stratification:** Multi-stage stratified sampling for household surveys
|
||||
- **Weighting:** Post-stratification weights to match population demographics
|
||||
|
||||
**Data Collection Instruments:**
|
||||
- **Instrument Type:** Varies by source - survey questionnaires (BLS), administrative records (Federal Reserve), market data feeds (financial indicators)
|
||||
- **Validation:** Source agencies conduct validation; FRED performs consistency checks
|
||||
- **Question Wording:** Standardized by source agencies (e.g., BLS labor force questions unchanged since 1994)
|
||||
- **Mode:** Computer-assisted telephone/personal interviews (CPS); online/mail (establishment surveys); automated (financial markets)
|
||||
|
||||
**Quality Control Procedures:**
|
||||
- **Field Supervision:** Conducted by source agencies (e.g., BLS field staff)
|
||||
- **Validation Rules:** FRED validates data consistency; checks for missing values, outliers, series breaks
|
||||
- **Consistency Checks:** Cross-series validation where applicable
|
||||
- **Verification:** Source agency quality control; FRED staff review data upon ingestion
|
||||
- **Outlier Treatment:** Flagged for review; extreme values investigated
|
||||
|
||||
**Error Characteristics:**
|
||||
- **Sampling Error:** Standard errors provided for survey-based estimates (BLS publishes confidence intervals)
|
||||
- **Non-sampling Error:** Measurement error in surveys (recall bias, response bias); coverage error (homeless, institutionalized populations often excluded)
|
||||
- **Known Biases:** Response bias in sentiment surveys; survivorship bias in labor surveys (excludes institutionalized)
|
||||
- **Accuracy Bounds:** Varies by series; CPS unemployment rate typically ±0.2 percentage points (95% CI); financial market data highly accurate
|
||||
|
||||
**Methodology Documentation:**
|
||||
- **Transparency Level:** 4/5 (Comprehensive) - source agencies publish detailed methodology; FRED documents sources
|
||||
- **Documentation URL:** https://fred.stlouisfed.org/docs/api/fred/ and source agency websites (e.g., BLS.gov)
|
||||
- **Peer Review Status:** Source agencies use peer-reviewed methods; BLS methodology reviewed by federal statistical standards
|
||||
- **Reproducibility:** High - published data reproducible using source agency methodology documentation
|
||||
|
||||
### Currency Assessment
|
||||
|
||||
**Update Characteristics:**
|
||||
- **Update Frequency:** Varies by series
|
||||
- STLFSI4 (Financial Stress): Weekly (every Friday)
|
||||
- UMCSENT (Consumer Sentiment): Monthly (preliminary mid-month, final end-of-month)
|
||||
- Unemployment indicators: Monthly (first Friday of month)
|
||||
- GINI Index: Annual (September release)
|
||||
- Debt Service Ratio: Quarterly (2-3 months after quarter end)
|
||||
- **Update Reliability:** Highly consistent; follows published release schedules
|
||||
- **Update Notification:** Email notifications available; RSS feeds; API can query release schedules
|
||||
- **Last Updated:** 2025-10-27 (current as of catalog entry)
|
||||
|
||||
**Timeliness:**
|
||||
- **Collection to Publication Lag:**
|
||||
- Financial indicators: 0-7 days (near real-time)
|
||||
- Monthly employment indicators: 10-14 days
|
||||
- Quarterly indicators: 60-90 days
|
||||
- Annual indicators: 9-12 months (e.g., GINI Index)
|
||||
- **Factors Affecting Timeliness:** Source agency processing schedules, data quality review, seasonal adjustment calculations
|
||||
- **Historical Timeliness:** Consistent; rare delays during government shutdowns or data collection disruptions
|
||||
|
||||
**Currency for Different Uses:**
|
||||
- **Real-time Analysis:** Suitable for weekly/monthly indicators (financial stress, unemployment, consumer sentiment)
|
||||
- **Recent Trends:** Excellent for tracking monthly/quarterly economic conditions
|
||||
- **Historical Research:** Excellent - decades of consistent time series for most indicators
|
||||
|
||||
### Objectivity Assessment
|
||||
|
||||
**Potential Biases:**
|
||||
|
||||
**Political Bias:**
|
||||
- **Government Influence:** Federal Reserve independence protects against political interference; data published regardless of political implications
|
||||
- **Editorial Stance:** Federal Reserve mandate is economic stability, not political advocacy; data presented objectively
|
||||
- **Political Pressure:** Federal Reserve Act guarantees independence; rare instances of political criticism of data, but data not altered
|
||||
|
||||
**Commercial Bias:**
|
||||
- **Funding Sources:** Federal Reserve self-funded through operations; not dependent on appropriations or commercial funding
|
||||
- **Advertising Influence:** Not applicable (non-commercial)
|
||||
- **Proprietary Interests:** None - public service mission
|
||||
|
||||
**Cultural/Social Bias:**
|
||||
- **Geographic Bias:** U.S.-centric; limited international coverage
|
||||
- **Social Perspective:** Economic perspective; traditional economic indicators may not capture all dimensions of wellbeing (e.g., unpaid work, environmental quality)
|
||||
- **Language Bias:** English primary language; limited translation
|
||||
- **Selection Bias:** Indicators reflect Federal Reserve priorities (employment, inflation, financial stability); some aspects of wellbeing underrepresented
|
||||
|
||||
**Transparency:**
|
||||
- **Bias Disclosure:** Source agencies acknowledge limitations; FRED provides source attribution and methodology links
|
||||
- **Limitations Stated:** Documented in series notes and source agency methodology documents
|
||||
- **Raw Data Available:** FRED provides access to source agency data; microdata available from some sources (e.g., Census Bureau)
|
||||
|
||||
### Reliability Assessment
|
||||
|
||||
**Consistency:**
|
||||
- **Internal Consistency:** High - automated consistency checks; series follow established patterns
|
||||
- **Temporal Consistency:** Excellent - long-running time series with consistent methodology; breaks clearly documented
|
||||
- **Cross-source Consistency:** Good agreement with other authoritative sources (e.g., OECD, World Bank for overlapping series)
|
||||
|
||||
**Stability:**
|
||||
- **Definition Changes:** Infrequent - BLS unemployment definitions stable since 1994; changes clearly marked
|
||||
- **Methodology Changes:** Source agencies announce methodology changes in advance; revisions documented
|
||||
- **Series Breaks:** Clearly marked in series notes; historical data often revised for consistency
|
||||
|
||||
**Verification:**
|
||||
- **Independent Verification:** Academic researchers, think tanks, international organizations use and validate FRED data
|
||||
- **Replication Studies:** Extensive use in published research; errors/discrepancies rare and corrected promptly
|
||||
- **Audit Results:** Federal Reserve subject to Office of Inspector General audits; data quality maintained
|
||||
|
||||
### Accuracy Assessment
|
||||
|
||||
**Validation Evidence:**
|
||||
- **Benchmark Comparisons:** BLS labor data validated against population benchmarks (decennial Census); financial data validated against market sources
|
||||
- **Coverage Assessments:** BLS publishes coverage rates (e.g., establishment survey covers ~30% of employment universe, weighted to 100%)
|
||||
- **Error Studies:** BLS publishes sampling error estimates; confidence intervals available for survey-based indicators
|
||||
|
||||
**Accuracy for Different Uses:**
|
||||
- **Point Estimates:** Highly accurate for administrative/market data (debt service, mortgage rates, financial stress); accurate within sampling error for survey data (unemployment ±0.2 pp)
|
||||
- **Trend Analysis:** Excellent for detecting medium-term trends (6+ months); month-to-month volatility within normal statistical variation
|
||||
- **Cross-sectional Comparison:** Reliable for comparing across time periods; caution needed for small changes within margin of error
|
||||
- **Sub-population Analysis:** Limited in FRED aggregated data; source agencies provide demographic breakdowns (available through direct agency access)
|
||||

## Known Limitations and Caveats
|
||||
|
||||
### Coverage Limitations
|
||||
|
||||
**Geographic Gaps:**
|
||||
- U.S. territories have limited coverage for some indicators
|
||||
- International data limited (primarily U.S. focus)
|
||||
- State/local data available for some series but not all wellbeing indicators
|
||||
|
||||
**Temporal Gaps:**
|
||||
- Historical data limited pre-1940s for most modern economic indicators
|
||||
- Some series discontinued or redefined over time (breaks in continuity)
|
||||
- Survey data may have gaps during collection disruptions (e.g., government shutdowns)
|
||||
|
||||
**Population Exclusions:**
|
||||
- Homeless populations typically excluded from household surveys
|
||||
- Institutionalized populations (prisons, nursing homes) excluded from labor force surveys
|
||||
- Undocumented immigrants underrepresented in surveys
|
||||
|
||||
**Variable Gaps:**
|
||||
- Limited demographic disaggregation in FRED aggregated data (detailed breakdowns require source agency access)
|
||||
- Wellbeing indicators focused on economic/financial dimensions; non-economic wellbeing (health, relationships, meaning) not captured
|
||||
- Underground economy not measured in official statistics
|
||||
|
||||
### Methodological Limitations
|
||||
|
||||
**Sampling Limitations:**
|
||||
- Household surveys subject to sampling error (confidence intervals provided)
|
||||
- Non-response bias in surveys (some demographics less likely to respond)
|
||||
- Survey redesigns can create discontinuities in time series
|
||||
|
||||
**Measurement Limitations:**
|
||||
- Self-reported data subject to recall bias, social desirability bias (sentiment surveys)
|
||||
- Consumer sentiment may not perfectly predict behavior
|
||||
- Credit card delinquency rates may lag actual financial distress (late fees, forbearance)
|
||||
- GINI index measures income inequality but not wealth inequality (wealth more concentrated than income)
|
||||
|
||||
**Processing Limitations:**
|
||||
- Seasonal adjustment can obscure actual values (seasonally adjusted vs. not seasonally adjusted)
|
||||
- Revisions common (preliminary→final data); early estimates subject to revision
|
||||
- Aggregation to national level masks regional/local variation
|
||||
|
||||
### Comparability Limitations
|
||||
|
||||
**Cross-national Comparability:**
|
||||
- U.S.-specific definitions may differ from international standards
|
||||
- Limited comparability with non-U.S. sources without careful definitional alignment
|
||||
- FRED primarily U.S.-focused; international comparisons require supplementary sources
|
||||
|
||||
**Temporal Comparability:**
|
||||
- Methodological changes over decades create series breaks (e.g., CPS redesign 1994)
|
||||
- Revisions to historical data (benchmark revisions can change entire series)
|
||||
- Inflation adjustment requires careful attention to base year
|
||||
|
||||
**Sub-group Comparability:**
|
||||
- Aggregated data in FRED limits demographic comparisons
|
||||
- Intersectional analysis not available (e.g., unemployment by race × age × education requires source agency data)
|
||||
|
||||
### Usage Caveats
|
||||
|
||||
**Inappropriate Uses:**
|
||||
1. **DO NOT use for individual/household-level analysis** - aggregated data only; use source agency microdata (e.g., Census Bureau, BLS) for individual-level research
|
||||
2. **DO NOT assume causation from correlations** - time series correlations do not imply causality; appropriate for hypothesis generation, not causal inference
|
||||
3. **DO NOT ignore revisions** - preliminary data subject to revision; use final/revised data for research
|
||||
4. **DO NOT compare across countries without adjusting for definitional differences** - U.S. definitions may differ from international standards
|
||||
5. **DO NOT use solely for comprehensive wellbeing assessment** - economic indicators only; supplement with health, education, social indicators
|
||||
|
||||
**Ecological Fallacy Risks:**
|
||||
- National-level trends don't necessarily apply to all individuals/regions
|
||||
- Example: National unemployment rate declining doesn't mean all regions/demographics experiencing improvement
|
||||
|
||||
**Correlation vs. Causation:**
|
||||
- FRED data appropriate for tracking economic conditions over time
|
||||
- Causal inference requires careful research design (natural experiments, instrumental variables, etc.), not simple time series analysis
|
||||
- Correlations between series may be spurious (common trends, third variable causation)
|
||||

||||
## Recommended Use Cases
|
||||
|
||||
### Ideal Applications
|
||||
|
||||
**Research Questions Well-Suited:**
|
||||
1. "How has household debt burden changed over the past 20 years?"
|
||||
2. "Is there a relationship between financial stress and unemployment?"
|
||||
3. "How do mortgage rate changes affect housing affordability?"
|
||||
4. "How has consumer sentiment tracked with major economic events (recessions, recoveries)?"
|
||||
5. "What is the trend in long-term unemployment during economic downturns?"
|
||||
|
||||
**Analysis Types Supported:**
|
||||
- Descriptive statistics (trends, levels, volatility)
|
||||
- Time series analysis (trends, seasonality, cycles)
|
||||
- Correlation analysis (relationships between economic indicators)
|
||||
- Event studies (impact of policy changes, economic shocks)
|
||||
- Forecasting (using historical patterns to predict short-term trends)
|
||||
|
||||
### Appropriate Contexts
|
||||
|
||||
**Geographic Contexts:**
|
||||
- United States national-level analysis
|
||||
- State-level analysis for select indicators (when state series available)
|
||||
- International comparisons (limited; requires supplementary sources)
|
||||
|
||||
**Temporal Contexts:**
|
||||
- Post-WWII economic analysis (1947-present for most indicators)
|
||||
- Recent trends (monthly/quarterly data available within weeks)
|
||||
- Historical research (decades of consistent data for most series)
|
||||
|
||||
**Subject Contexts:**
|
||||
- Household economic wellbeing and financial security
|
||||
- Labor market conditions and employment
|
||||
- Consumer confidence and sentiment
|
||||
- Housing affordability and mortgage markets
|
||||
- Income inequality and economic disparities
|
||||
- Financial system stress and stability
|
||||
|
||||
### Use Warnings
|
||||
|
||||
**Avoid Using This Source For:**
|
||||
1. **Individual/household microdata analysis** → Use Census Bureau, BLS microdata instead
|
||||
2. **International comparisons without careful alignment** → Use World Bank, OECD for cross-country analysis
|
||||
3. **Subnational granularity beyond state-level** → Use state/local statistical agencies
|
||||
4. **Non-economic wellbeing dimensions** → Use health, education, social indicator sources
|
||||
5. **Real-time intraday economic data** → Use commercial financial data providers (Bloomberg, Reuters)
|
||||
|
||||
**Recommended Alternatives For:**
|
||||
- Individual-level analysis → Census Bureau microdata (IPUMS), BLS microdata (CPS, NLSY)
|
||||
- International comparisons → World Bank Open Data, OECD Data
|
||||
- Subnational detail → State labor departments, metropolitan statistical area data from source agencies
|
||||
- Non-economic wellbeing → WHO GHO (health), UN SDG (comprehensive development), Gallup World Poll (subjective wellbeing)
|
||||
- Comprehensive inequality → World Inequality Database (wealth inequality, income inequality with more detail)

## Cataloger Notes
|
||||
|
||||
**Internal Notes:**
|
||||
- Excellent source; high authority; essential for Substrate economic wellbeing domain
|
||||
- API well-documented, stable, and easy to use
|
||||
- Selected 10 core wellbeing indicators from 1.3M+ series for focused tracking
|
||||
- Weekly financial stress indicator provides high-frequency wellbeing monitoring
|
||||
- Consider adding state-level economic indicators as separate entries or expanded coverage
|
||||
|
||||
**To Do:**
|
||||
- [ ] Add related organizations (Federal Reserve System, BLS, Census Bureau, BEA)
|
||||
- [ ] Cross-reference with relevant Problems and Solutions
|
||||
- [ ] Create update script for regular data refreshes
|
||||
- [ ] Test update script with sample API calls
|
||||
- [ ] Monitor API changes and rate limit compliance
|
||||
|
||||
**Questions for Review:**
|
||||
- Should we expand to more indicators beyond core 10 wellbeing series?
|
||||
- How to handle state-level data (separate source entry vs. expanded coverage)?
|
||||
- Should we create separate entries for different economic domains (labor, housing, finance)?

# CDC WONDER Mortality Database - Data Directory
|
||||
|
||||
**Source ID:** DS-00005
|
||||
|
||||
This directory contains data files fetched from the CDC WONDER Mortality Database API.
|
||||
|
||||
## File Structure
|
||||
|
||||
### Raw JSON Files
|
||||
- `drugOverdose_latest.json` - Drug overdose deaths (ICD-10: X40-X44, X60-X64, X85, Y10-Y14)
|
||||
- `opioid_latest.json` - Opioid-specific deaths (ICD-10: T40.0-T40.4, T40.6)
|
||||
- `suicide_latest.json` - Suicide deaths (ICD-10: X60-X84, Y87.0, U03)
|
||||
- `allCause_latest.json` - All-cause mortality
|
||||
- `all_queries_latest.json` - Combined dataset from all queries
|
||||
|
||||
### Transformed Pipe-Delimited Files
|
||||
- `drugOverdose_latest.txt` - Drug overdose deaths in Substrate format
|
||||
- `opioid_latest.txt` - Opioid deaths in Substrate format
|
||||
- `suicide_latest.txt` - Suicide deaths in Substrate format
|
||||
- `allCause_latest.txt` - All-cause mortality in Substrate format
|
||||
|
||||
## Data Format
|
||||
|
||||
### Raw JSON
|
||||
Array of mortality records with fields:
|
||||
- `state` - US state name
|
||||
- `year` - Year of death
|
||||
- `deaths` - Number of deaths
|
||||
- `population` - Population (if available)
|
||||
- `crudeRate` - Crude death rate per 100,000
|
||||
- `ageAdjustedRate` - Age-adjusted death rate per 100,000 (if available)
|
||||
|
||||
### Pipe-Delimited Format
|
||||
Substrate standard format:
|
||||
```
|
||||
RECORD ID | QUERY TYPE | STATE | YEAR | DEATHS | POPULATION | CRUDE RATE | AGE ADJUSTED RATE
|
||||
DS-00005-drugOverdose-California-2020 | Drug Overdose Deaths | California | 2020 | 5000 | 39538223 | 12.6 | N/A
|
||||
```
|
||||
|
||||
## Update Process
|
||||
|
||||
Run the update script to fetch latest data:
|
||||
|
||||
```bash
|
||||
bun run update.ts
|
||||
```
|
||||
|
||||
## Data Coverage
|
||||
|
||||
- **Geographic:** All US states + DC + territories
|
||||
- **Temporal:** 1999-present (ICD-10 era); most recent data typically 1-2 years lag
|
||||
- **Frequency:** Annual updates (final data); quarterly (provisional data)
|
||||
- **Completeness:** Census (100% of deaths, not sample)
|
||||
|
||||
## Important Notes
|
||||
|
||||
### Cell Suppression
|
||||
CDC WONDER suppresses cells with counts <10 to protect privacy. Suppressed cells appear as "Suppressed" in results.
|
||||
|
||||
### Data Quality
|
||||
- Drug overdose deaths: May be undercounted by 10-20% due to incomplete toxicology testing
|
||||
- Suicide deaths: Estimated 20-35% undercount due to classification challenges
|
||||
- Provisional data: Subject to revision when finalized (can change by 5-10%)
|
||||
|
||||
### Rate Calculations
|
||||
- Crude Rate: Deaths per 100,000 population
|
||||
- Age-Adjusted Rate: Standardized to 2000 US standard population (enables comparability across populations with different age structures)

- Authoritative source for US mortality statistics (legal authority)
|
||||
- Best source for "deaths of despair" - drug overdoses, suicides, alcohol-related deaths
|
||||
- Census data (complete enumeration, not sample)
|
||||
- Leading indicator of population wellbeing breakdown (behavioral revealed preference)
|
||||
- County-level granularity shows geographic variation in health crises
|
||||
|
||||
**What This Source IS NOT:**
|
||||
- NOT real-time surveillance (1-2 year lag for final data; months for provisional)
|
||||
- NOT individual-level microdata (aggregated to protect privacy; individual records require restricted use agreement)
|
||||
- NOT international data (US only)
|
||||

||||
|
||||
**Comparison with Similar Sources:**
|
||||
|
||||
| Source | Advantages Over CDC WONDER | Disadvantages vs. CDC WONDER |
|
||||
|--------|---------------------------|------------------------------|
|
||||
| State Vital Statistics | More timely (6-12 month lag vs. 1-2 years); may have additional state-specific variables | Single state only; interstate comparisons require standardization; state definitions may vary |
|
||||
| WHO Mortality Database | International coverage; standardized for cross-country comparison | US data less timely than CDC WONDER; less detailed cause-of-death coding; no county-level data |
|
||||

## Source Evaluation Narrative
|
||||
|
||||
### Methodological Assessment
|
||||
|
||||
**Data Collection Methodology:**
|
||||
|
||||
**Sampling Design:**
|
||||
- **Method:** Census (complete enumeration, not sample)
|
||||
- **Sample Size:** N/A (all deaths in US)
|
||||
- **Sampling Frame:** N/A (universal death registration)
|
||||
- **Stratification:** N/A (census)
|
||||
- **Weighting:** Not applicable (census data)
|
||||
|
||||
**Data Collection Instruments:**
|
||||
- **Instrument Type:** US Standard Certificate of Death (standardized form used by all states)
|
||||
- **Validation:** Form developed by NCHS in collaboration with states; legally mandated
|
||||
- **Question Wording:** Standardized across all states
|
||||
- **Mode:** Medical certifier completes cause of death; funeral director completes demographic information; filed with state vital records office
|
||||
|
||||
**Quality Control Procedures:**
|
||||
- **Field Supervision:** State vital registrars oversee completeness and timeliness
|
||||
- **Validation Rules:** NCHS automated coding and quality checks (ACME - Automated Classification of Medical Entities)
|
||||
- **Consistency Checks:** Age/cause consistency, geographic code validation, demographic completeness checks
|
||||
- **Verification:** Query resolution process for problematic records; state vital registrars verify and correct
|
||||
- **Outlier Treatment:** Statistical outliers flagged; investigated if data quality issue suspected
|
||||
|
||||
**Error Characteristics:**
|
||||
- **Sampling Error:** None (census, not sample)
|
||||
- **Non-sampling Error:**
|
||||
- Misclassification of cause of death (especially for drug-involved deaths - toxicology delays)
|
||||
- Underreporting of suicides (coroner determination variability; stigma leading to misclassification)
|
||||
- Geographic misattribution (death location vs. residence; some states report location of death)
|
||||
- Timeliness issues (toxicology delays can cause 6-12 month lag in drug-involved death counts)
|
||||
- **Known Biases:**
|
||||
- Suicide undercounting (stigma; medicolegal determination inconsistency across jurisdictions)
|
||||
- Drug overdose specificity varies (some states better at toxicology testing/reporting)
|
||||
- Racial/ethnic misclassification (especially for American Indian/Alaska Native populations)
|
||||
- **Accuracy Bounds:**
|
||||
- Overall mortality: 99%+ complete (near-universal death registration)
|
||||
- Cause of death: 90-95% accuracy for broad categories; 70-85% for specific subcategories
|
||||
- Drug-involved deaths: ~10-20% undercount estimated due to lack of toxicology testing or pending investigations
|
||||
|
||||
**Methodology Documentation:**
|
||||
- **Transparency Level:** 5/5 (Comprehensive)
|
||||
- **Documentation URL:** https://www.cdc.gov/nchs/nvss/mortality_methods.htm
|
||||
- **Peer Review Status:** Methods published in peer-reviewed journals (Vital Statistics Reports series); reviewed by NCVHS
|
||||
- **Reproducibility:** High - ICD-10 coding rules publicly available; ACME software documented
|
||||
|
||||
### Currency Assessment
|
||||
|
||||
**Update Characteristics:**
|
||||
- **Update Frequency:** Annual (final data); quarterly (provisional data)
|
||||
- **Update Reliability:** Consistent annual release schedule (December for prior year's final data)
|
||||
- **Update Notification:** Email notifications available; NCHS website announcements; RSS feed
|
||||
- **Last Updated:** 2024-12-15 (2022 final data released); 2025-06-01 (2023 provisional data)
|
||||
|
||||
**Timeliness:**
|
||||
- **Collection to Publication Lag:**
|
||||
- Provisional data: 3-6 months (quarterly releases)
|
||||
- Final data: 12-24 months (annual release, typically 11-14 months after year-end)
|
||||
- Factors: State reporting timelines, toxicology testing delays, quality assurance, ICD-10 coding
|
||||
- **Factors Affecting Timeliness:**
|
||||
- State vital registrars' submission schedules (vary by state)
|
||||
- Toxicology testing delays (drug-involved deaths)
|
||||
- Medicolegal investigations (homicides, suicides, overdoses)
|
||||
- Quality review and coding processes
|
||||
- **Historical Timeliness:** Generally consistent; COVID-19 pandemic accelerated provisional data releases (2020-2021)
|
||||
|
||||
**Currency for Different Uses:**
|
||||
- **Real-time Analysis:** Unsuitable - 3-24 month lag
|
||||
- **Recent Trends:** Suitable for annual trends (provisional data); unsuitable for sub-annual trends
|
||||
- **Historical Research:** Excellent - consistent time series 1999-present (ICD-10 era)
|
||||
|
||||
### Objectivity Assessment
|
||||
|
||||
**Potential Biases:**
|
||||
|
||||
**Political Bias:**
|
||||
- **Government Influence:** Data collection mandated by law; NCHS has scientific independence protections; political pressure rare but possible (e.g., pressure to downplay opioid crisis)
|
||||
- **Editorial Stance:** NCHS maintains scientific neutrality; publishes data regardless of political implications
|
||||
- **Political Pressure:** Occasional controversies (e.g., CDC gun violence research restrictions 1996-2018); generally data publication protected
|
||||
|
||||
**Commercial Bias:**
|
||||
- **Funding Sources:** Federal appropriations only; no industry funding
|
||||
- **Advertising Influence:** Not applicable (government agency)
|
||||
- **Proprietary Interests:** None
|
||||
|
||||
**Cultural/Social Bias:**
|
||||
- **Geographic Bias:** Better data quality in states with well-resourced vital registration systems and comprehensive toxicology testing; rural areas may have less complete death investigation
|
||||
- **Social Perspective:** Biomedical model of cause of death; limited capture of social determinants (poverty, discrimination, etc. not coded)
|
||||
- **Language Bias:** English; Spanish translations limited
|
||||
- **Selection Bias:** Suicide and overdose definitions subject to medicolegal determination - social stigma and local practices affect classification consistency
|
||||
|
||||
**Transparency:**
|
||||
- **Bias Disclosure:** NCHS acknowledges data quality limitations by state; documentation notes known issues (e.g., suicide undercount, toxicology testing variation)
|
||||
- **Limitations Stated:** Comprehensive - technical documentation details limitations
|
||||
- **Raw Data Available:** Aggregated data public; individual death records available under restricted-use agreement with strict confidentiality protections
|
||||
|
||||
### Reliability Assessment
|
||||
|
||||
**Consistency:**
|
||||
- **Internal Consistency:** High - validation rules ensure logical consistency (age/cause, location codes)
|
||||
- **Temporal Consistency:** Excellent within ICD-10 era (1999+); series break at ICD-9/ICD-10 transition (1998-1999)
|
||||
- **Cross-source Consistency:** Matches state vital statistics (NCHS aggregates state data); minor discrepancies due to timing differences
|
||||
|
||||
**Stability:**
|
||||
- **Definition Changes:** Rare within ICD-10 era; ICD-11 transition planned (multi-year advance notice)
|
||||
- **Methodology Changes:** ACME coding updates documented; typically minor; comparability maintained
|
||||
- **Series Breaks:** Major break at ICD-9/ICD-10 transition (1998-1999); ICD-11 transition will create future break (planned for late 2020s with bridge-coding period)
|
||||
|
||||
**Verification:**
|
||||
- **Independent Verification:** State vital statistics are primary source; academic researchers validate using hospital records, medical examiner reports (generally corroborate NCHS)
|
||||
- **Replication Studies:** Extensive academic use; errors reported and corrected in subsequent releases
|
||||
- **Audit Results:** GAO audits of federal statistical programs; NCHS passes audits; data quality assessments published periodically
|
||||
|
||||
### Accuracy Assessment
|
||||
|
||||
**Validation Evidence:**
|
||||
- **Benchmark Comparisons:** Comparison with state vital statistics: 99%+ agreement for counts; <1% differences attributable to timing and geography coding
|
||||
- **Coverage Assessments:** Death registration completeness estimated >99%; periodic studies confirm near-universal coverage
|
||||
- **Error Studies:**
|
||||
- Cause-of-death accuracy studies: 70-95% agreement depending on cause specificity (higher for broad categories, lower for specific subcategories)
|
||||
- Drug-involved death studies: Estimated 10-20% undercount due to lack of toxicology testing or pending investigations
|
||||
|
||||
**Accuracy for Different Uses:**
|
||||
- **Point Estimates:** Highly reliable for all-cause mortality (99%+ complete); reliable for major causes (90-95%); moderate reliability for drug/suicide subcategories (70-90% due to classification challenges)
|
||||
- **Trend Analysis:** Highly reliable for multi-year trends (5+ years); be cautious with year-to-year changes (can reflect changes in investigation/testing practices, not just true mortality changes)
|
||||
- **Cross-sectional Comparison:** Reliable for state comparisons; caution for county comparisons (small counties have cell suppression; rate instability)
|
||||
- **Sub-population Analysis:** Reliable for sex, broad age groups, major racial/ethnic categories; limited for detailed age, race/ethnicity intersections (small cell suppression)
|
||||

## Known Limitations and Caveats
|
||||
|
||||
### Coverage Limitations
|
||||
|
||||
**Geographic Gaps:**
|
||||
- US citizens dying abroad generally not included (consular reports incomplete)
|
||||
- Some territories have incomplete coverage (American Samoa, Guam variable completeness)
|
||||
- Tribal lands: Data completeness varies; some tribes opt out of state reporting
|
||||
|
||||
**Temporal Gaps:**
|
||||
- ICD-9 to ICD-10 transition (1998-1999) creates comparability break
|
||||
- Provisional data subject to revision (can change by 5-10% when finalized)
|
||||
- Toxicology-delayed deaths appear in later data releases (can shift apparent temporal patterns)
|
||||
|
||||
**Population Exclusions:**
|
||||
- Fetal deaths excluded (separate database)
|
||||
- Non-residents dying in US included in total counts but can be excluded in analyses
|
||||
- Missing race/ethnicity data (5-10% of records have race/ethnicity categorized as "unknown")
|
||||
|
||||
**Variable Gaps:**
|
||||
- Social determinants (income, education, occupation) captured incompletely on death certificate
|
||||
- Mental health history not systematically captured (unless contributory cause of death)
|
||||
- Substance use history limited (only if documented as cause of death)
|
||||
- Intent determination (suicide vs. unintentional vs. undetermined) varies by jurisdiction
|
||||
|
||||
### Methodological Limitations
|
||||
|
||||
**Sampling Limitations:**
|
||||
- Not applicable (census data)
|
||||
|
||||
**Measurement Limitations:**
|
||||
- **Cause of death accuracy:**
|
||||
- Depends on certifier knowledge and diagnostic information available
|
||||
- Toxicology testing not universal (drug-involved deaths undercounted)
|
||||
- Autopsy rates declining (less diagnostic certainty)
|
||||
- Multiple cause coding: ICD allows only one underlying cause; contributing causes captured but less commonly analyzed
|
||||
- **Suicide undercounting:**
|
||||
- Requires medicolegal determination of intent
|
||||
- Stigma may discourage suicide classification
|
||||
- Coroner/medical examiner practices vary by jurisdiction
|
||||
- Estimated 20-35% undercount (academic studies)
|
||||
- **Drug overdose specificity:**
|
||||
- Requires toxicology testing (not always performed)
|
||||
- Some states better at specific drug identification (opioid type, fentanyl vs. heroin)
|
||||
- "Unspecified" drug codes used when testing incomplete
|
||||
|
||||
**Processing Limitations:**
|
||||
- ACME automated coding: Can misclassify complex cases (human review limited to flagged records)
|
||||
- ICD-10 coding rules: May not align with clinical understanding (e.g., diabetes contributory but not underlying cause)
|
||||
- Geographic coding: Death occurrence location vs. residence - API default is residence but some analyses use occurrence
|
||||
- Cell suppression: Counts <10 suppressed (limits small-area analysis)
|
||||
|
||||
### Comparability Limitations
|
||||
|
||||
**Cross-national Comparability:**
|
||||
- ICD-10 coding rules vary slightly by country (WHO provides guidelines but countries adapt)
|
||||
- Medicolegal systems differ (coroner vs. medical examiner; death investigation resources)
|
||||
- Toxicology testing practices vary internationally
|
||||
- Use WHO Mortality Database for international comparisons (standardized for comparability)
|
||||
|
||||
**Temporal Comparability:**
|
||||
- ICD-9 to ICD-10 transition (1998-1999): Major break; NCHS provides comparability ratios for selected causes
|
||||
- Within ICD-10 era: Generally comparable but be aware of:
|
||||
- Changes in autopsy rates (declining over time)
|
||||
- Changes in toxicology testing practices (fentanyl testing increased post-2015)
|
||||
- Changes in suicide investigation practices (some jurisdictions more consistent over time)
|
||||
- Opioid prescribing changes affect overdose patterns (prescription monitoring programs, prescribing guidelines)
|
||||
|
||||
**Sub-group Comparability:**
|
||||
- Small counties: Cell suppression and rate instability
|
||||
- Racial/ethnic groups: Misclassification issues (especially American Indian/Alaska Native - estimated 30-40% misclassified)
|
||||
- Age groups: Comparability high; infant mortality in separate specialized reports
|
||||
- Intersectional analysis: Limited by small cell suppression (e.g., sex × race × county × cause)
|
||||
|
||||
### Usage Caveats
|
||||
|
||||
**Inappropriate Uses:**
|
||||
1. **DO NOT use for real-time surveillance** - 3-24 month lag; use syndromic surveillance for real-time
|
||||
2. **DO NOT assume suicide counts are complete** - 20-35% estimated undercount; use as lower bound
|
||||
3. **DO NOT compare small counties without considering rate instability** - use multi-year aggregates or suppress unstable rates
|
||||
4. **DO NOT infer causation from geographic correlations** - ecological fallacy; state-level associations don't imply individual-level
|
||||
5. **DO NOT attempt to re-identify individuals** - violation of CIPSEA; cell suppression protects privacy
|
||||
|
||||
**Ecological Fallacy Risks:**
|
||||
- County-level associations (e.g., unemployment rate and overdose deaths) don't necessarily hold at individual level
|
||||
- State-level policies correlated with outcomes may reflect confounding (states adopting policies differ in other ways)
|
||||
- Example: States with higher opioid prescribing have higher overdose deaths - doesn't mean all overdose decedents had prescriptions (ecological correlation)
|
||||
|
||||
**Correlation vs. Causation:**
|
||||
- Data appropriate for descriptive epidemiology (who, what, where, when)
|
||||
- Analytical epidemiology (why) requires individual-level data, confounding control, causal inference methods
|
||||
- Geographic/temporal correlations can generate hypotheses but not test causal mechanisms
|
||||

## Recommended Use Cases
|
||||
|
||||
### Ideal Applications
|
||||
|
||||
**Research Questions Well-Suited:**
|
||||
1. "How have drug overdose deaths changed over time in the United States?"
|
||||
2. "Which states and counties have the highest suicide rates?"
|
||||
3. "What is the geographic pattern of opioid-involved deaths?"
|
||||
4. "How do premature death rates (YPLL) vary by state?"
|
||||
5. "What are the leading causes of death in the United States by age group?"
|
||||
6. "How did state opioid prescribing policies correlate with overdose trends?"
|
||||
|
||||
**Analysis Types Supported:**
|
||||
- Descriptive statistics (counts, rates by geography/demographics)
|
||||
- Trend analysis (time series 1999-present)
|
||||
- Geographic analysis (state, county-level mapping)
|
||||
- Age-standardization for comparability across populations
|
||||
- Premature death burden (YPLL before age 75)
|
||||
- Multiple cause-of-death analysis (contributing causes)
|
||||
- Policy evaluation (ecological studies of state interventions)
|
||||
|
||||
### Appropriate Contexts
|
||||
|
||||
**Geographic Contexts:**
|
||||
- US national trends
|
||||
- State-level comparisons (all 50 states + DC)
|
||||
- County-level analysis (caution: small counties have suppression and rate instability; use multi-year aggregates)
|
||||
- Regional aggregations (Census regions, HHS regions)
|
||||
|
||||
**Temporal Contexts:**
|
||||
- Long-term trends (1999-present for ICD-10 era)
|
||||
- Medium-term trends (5-10 years most reliable)
|
||||
- Annual trends (final data preferred; provisional data for recent years)
|
||||
- Historical research (especially post-1999 ICD-10 transition)
|
||||
|
||||
**Subject Contexts:**
|
||||
- Opioid epidemic research (overdose deaths by drug type)
|
||||
- Suicide prevention (suicide trends by demographics, geography, method)
|
||||
- "Deaths of despair" (combined drug/alcohol/suicide mortality)
|
||||
- Premature death burden (YPLL)
|
||||
- All-cause mortality trends
|
||||
- Cause-specific mortality (heart disease, cancer, accidents, etc.)
|
||||
|
||||
### Use Warnings
|
||||
|
||||
**Avoid Using This Source For:**
|
||||
1. **Real-time outbreak detection** → Use syndromic surveillance, poison control data
|
||||
2. **Individual-level research** → Use restricted-use microdata (requires RUA)
|
||||
3. **Small-area analysis (<100,000 population)** → Use multi-year aggregates; accept suppression limits
|
||||
4. **Complete suicide counts** → Treat as lower bound (20-35% undercount)
|
||||
5. **International comparisons** → Use WHO Mortality Database (standardized for comparability)
|
||||
6. **Nonfatal outcomes** → Use NEISS, HCUP, emergency department data
|
||||
|
||||
**Recommended Alternatives For:**
|
||||
- Real-time surveillance → NSSP (syndromic surveillance), NNDSS (notifiable diseases)
|
||||
- Individual-level analysis → Restricted-use NCHS microdata (requires RUA)
|
||||
- Nonfatal injuries → NEISS (National Electronic Injury Surveillance System)
|
||||
- Detailed violent death circumstances → NVDRS (National Violent Death Reporting System)
|
||||
- More timely state data → State vital statistics departments (6-12 month lag)
|
||||
- International data → WHO Mortality Database (standardized for cross-country comparisons)

## Cataloger Notes
|
||||
|
||||
**Internal Notes:**
|
||||
- **CRITICAL SOURCE** for Substrate: Reveals behavioral truth (revealed preference) that surveys miss
|
||||
- Drug overdoses and suicides are **leading indicators** of wellbeing breakdown - precede economic decline
|
||||
- County-level granularity enables geographic analysis (shows "left behind" places)
|
||||
- Census data (not sample) - captures all deaths
|
||||
- Main limitation: 1-2 year lag (but still best available US mortality data)
|
||||
- Suicide undercounting known issue (~20-35% undercount) - use as lower bound
|
||||
- API is XML-based (not REST/JSON) - more complex than WHO API but well-documented
|
||||
|
||||
**To Do:**
|
||||
- [x] Create update.ts script for XML API
|
||||
- [ ] Test API with sample drug overdose query (ICD-10: X40-X44)
|
||||
- [ ] Cross-reference with relevant Problems (opioid epidemic, suicide, deaths of despair)
|
||||
- [ ] Cross-reference with relevant Solutions (harm reduction, MAT, PDMPs)
|
||||
- [ ] Add NVDRS as complementary source when cataloged
|
||||
- [ ] Monitor ICD-11 transition timeline (check NCHS announcements)
|
||||
|
||||
**Questions for Review:**
|
||||
- Should we catalog multiple WONDER databases separately (mortality vs. natality vs. cancer) or keep as related sources?
|
||||
- How to handle provisional vs. final data in updates (separate files or versioning)?
|
||||
- County suppression rules - how to represent suppressed cells in Substrate format?

# ACS Social Wellbeing Data Directory
|
||||
|
||||
This directory contains data fetched from the US Census Bureau American Community Survey (ACS) API.
|
||||
|
||||
## Data Files
|
||||
|
||||
### Latest Data
|
||||
- `latest.json` - Most recent ACS 1-year estimates (all variable groups combined)
|
||||
|
||||
### Annual Data Files
|
||||
Files are named using the pattern: `{year}-{estimate_type}-{variable_group}-{geography_level}.{format}`
|
||||
|
||||
Example filenames:
|
||||
- `2022-acs1-household-states.json` - 2022 1-year household composition data for all states
|
||||
- `2022-acs1-commute-states.txt` - 2022 1-year commute data in pipe-delimited format
|
||||
- `2018_2022-acs5-digital-states.json` - 2018-2022 5-year digital access data
|
||||
|
||||
### Variable Groups
|
||||
|
||||
**household** - Household composition and social isolation indicators
|
||||
- B11001_001E/M: Total households
|
||||
- B11001_008E/M: 1-person households (living alone)
|
||||
- B11002_003E/M: Family households
|
||||
- B11002_010E/M: Nonfamily households
|
||||
|
||||
**commute** - Commuting and time poverty indicators
|
||||
- B08303_001E/M: Mean travel time to work
|
||||
- B08303_013E/M: Workers with 60+ minute commute
|
||||
- B08134_011E/M: Long commute, low income workers
|
||||
|
||||
**digital** - Digital divide and internet access
|
||||
- B28002_013E/M: No internet access at home
|
||||
- B28002_004E/M: Broadband internet subscription
|
||||
- B28003_005E/M: No computer in household
|
||||
|
||||
**economic** - Economic security indicators
|
||||
- B19013_001E/M: Median household income
|
||||
- B25064_001E/M: Median gross rent
|
||||
- B23025_005E/M: Unemployed population
|
||||
- B17001_002E/M: Population below poverty line
|
||||
|
||||
### Variable Naming Convention
|
||||
|
||||
All ACS variables follow this pattern: `{table}_{sequence}{type}`
|
||||
|
||||
- **table**: Table ID (e.g., B11001)
|
||||
- **sequence**: Line number within table (e.g., 001, 008)
|
||||
- **type**:
|
||||
- `E` = Estimate (point estimate)
|
||||
- `M` = Margin of Error (90% confidence interval)
|
||||
|
||||
Example: `B11001_008E` = Estimate of 1-person households from Table B11001, line 008
|
||||
|
||||
## Data Formats
|
||||
|
||||
### JSON Format
|
||||
Raw data from Census API in JSON array format.
|
||||
|
||||
### Pipe-Delimited Format (.txt)
|
||||
Substrate-standard format with structure:
|
||||
```
|
||||
RECORD ID | GEOGRAPHY | NAME | VARIABLE | ESTIMATE | MARGIN_OF_ERROR | YEAR | ESTIMATE_TYPE
|
||||
```
|
||||
|
||||
## Update Process
|
||||
|
||||
Data is updated by running the `update.ts` script:
|
||||
|
||||
```bash
|
||||
# Set API key (required)
|
||||
export CENSUS_API_KEY=your_api_key_here
|
||||
|
||||
# Run update
|
||||
./update.ts
|
||||
```
|
||||
|
||||
### Rate Limits
|
||||
- 500 requests per day per API key
|
||||
- Script includes automatic rate limiting (2 second delays between requests)
|
||||
- Progress logged to `update.log`
|
||||
|
||||
## Data Quality Notes
|
||||
|
||||
### Margins of Error (MOE)
|
||||
All estimates include margins of error (90% confidence intervals).
|
||||
|
||||
**Statistical testing:**
|
||||
- If MOEs overlap, difference may not be statistically significant
|
||||
- Use Census Bureau's statistical testing tool: https://www.census.gov/programs-surveys/acs/guidance/statistical-testing-tool.html
|
||||
|
||||
### Estimate Types
|
||||
|
||||
**1-Year Estimates:**
|
||||
- Most current data
|
||||
- Available for geographies with 65,000+ population
|
||||
- Higher sampling error (larger MOEs)
|
||||
- Use for large areas and recent snapshots
|
||||
|
||||
**5-Year Estimates:**
|
||||
- More reliable (smaller MOEs)
|
||||
- Available for all geographic levels (including census tracts)
|
||||
- Represents average over 5-year period
|
||||
- Use for small areas and stable characteristics
|
||||
|
||||
**Caution:** Do not compare overlapping multi-year estimates (e.g., 2017-2021 vs 2018-2022 share 4 years of data)
|
||||

## Source Evaluation Narrative
|
||||
|
||||
### Methodological Assessment
|
||||
|
||||
**Data Collection Methodology:**
|
||||
|
||||
**Sampling Design:**
|
||||
- **Method:** Stratified systematic sample (address-based sampling frame)
|
||||
- **Sample Size:** 3.5 million addresses annually (~2.5% of US housing units)
|
||||
- **Sampling Frame:** Master Address File (MAF) - comprehensive list of all US addresses
|
||||
- **Stratification:** Geographic (states required to have adequate sample), housing unit characteristics
|
||||
- **Weighting:** Complex weighting to match population controls from population estimates program
|
||||
|
||||
**Data Collection Instruments:**
|
||||
- **Instrument Type:** Standardized questionnaire (paper, web, telephone, in-person)
|
||||
- **Validation:** Cognitive testing; field testing; OMB approval under Paperwork Reduction Act
|
||||
- **Question Wording:** Standardized across modes; questions tested for comprehension and bias
|
||||
- **Mode:** Mixed-mode (mail/internet primary, telephone/in-person follow-up for nonresponse)
|
||||
|
||||
**Quality Control Procedures:**
|
||||
- **Field Supervision:** Regional census centers supervise field operations; real-time quality monitoring
|
||||
- **Validation Rules:** Automated edit and imputation procedures for missing/inconsistent responses
|
||||
- **Consistency Checks:** Cross-variable edits (e.g., age vs. school enrollment)
|
||||
- **Verification:** Reinterview program (10% sample) to verify data collection quality
|
||||
- **Outlier Treatment:** Statistical edit procedures identify and resolve outliers; extreme values flagged for review
|
||||
|
||||
**Error Characteristics:**
|
||||
- **Sampling Error:** Margins of error (MOE) published for all estimates; 90% confidence intervals
|
||||
- **Non-sampling Error:** Known issues: nonresponse bias (mitigated by weighting); measurement error in self-reported income, housing values; coverage error (undercounting of hard-to-count populations)
|
||||
- **Known Biases:** Nonresponse bias in high-poverty, high-minority areas (mitigated through weighting); social desirability bias for sensitive questions
|
||||
- **Accuracy Bounds:** MOEs published; typical MOE ±3-5% for large geographies, ±10-20% for small areas/rare characteristics
|
||||
|
||||
**Methodology Documentation:**
|
||||
- **Transparency Level:** 5/5 (Exemplary)
|
||||
- **Documentation URL:** https://www.census.gov/programs-surveys/acs/methodology.html
|
||||

|
||||
- **Reproducibility:** Full methodology documentation; PUMS microdata enable replication; R/Python packages provide reproducible workflows
|
||||
|
||||
### Currency Assessment
|
||||
|
||||
**Update Characteristics:**
|
||||
- **Update Frequency:** Annual (1-year estimates published ~September of following year; 5-year estimates published ~December)
|
||||
- **Update Reliability:** Consistent annual schedule; rare delays
|
||||
- **Update Notification:** Email subscription; data release schedule published annually
|
||||
- **Last Updated:** 2023-09-14 (2022 1-year estimates); 2023-12-07 (2018-2022 5-year estimates)
|
||||
|
||||
**Timeliness:**
|
||||
- **Collection to Publication Lag:**
|
||||
- 1-Year Estimates: ~9 months (data collected Jan-Dec 2022 → published Sept 2023)
|
||||
- 5-Year Estimates: ~1 year after period end (2018-2022 data → published Dec 2023)
|
||||
- **Factors Affecting Timeliness:** Data processing, quality review, disclosure avoidance procedures
|
||||
- **Historical Timeliness:** Generally consistent; COVID-19 pandemic caused operational changes in 2020 (noted in documentation)
|
||||
|
||||
**Currency for Different Uses:**
|
||||
- **Real-time Analysis:** Unsuitable - 9-12 month lag
|
||||
- **Recent Trends:** Suitable for annual trend analysis; 5-year estimates smooth year-to-year fluctuations
|
||||
- **Historical Research:** Excellent - consistent time series 2005-present
|
||||
|
||||
### Objectivity Assessment
|
||||
|
||||
**Potential Biases:**
|
||||
|
||||
**Political Bias:**
|
||||
- **Government Influence:** Census Bureau operates under Title 13 USC protections ensuring statistical independence from political influence
|
||||
- **Editorial Stance:** Neutral; data published regardless of political implications
|
||||
- **Political Pressure:** Rare instances of political pressure on citizenship question (2020 census controversy); ACS questions unchanged
|
||||
|
||||
**Commercial Bias:**
|
||||
- **Funding Sources:** Congressional appropriations only; no commercial funding
|
||||
- **Advertising Influence:** Not applicable
|
||||
- **Proprietary Interests:** None - all data public domain
|
||||
|
||||
**Cultural/Social Bias:**
|
||||
- **Geographic Bias:** Sample design ensures representation of all geographies; small-area estimates have higher uncertainty
|
||||
- **Social Perspective:** Questions developed through public input process; tested across diverse populations; some constructs (household, family) reflect legal/administrative definitions that may not capture all lived experiences
|
||||
- **Language Bias:** Questionnaire available in English and Spanish; telephone assistance in multiple languages; written translations limited
|
||||
- **Selection Bias:** Question coverage prioritizes federal data needs (OMB standards); some state/local priority topics not included
|
||||
|
||||
**Transparency:**
|
||||
- **Bias Disclosure:** Census Bureau acknowledges data quality issues by geography; MOEs published
|
||||
- **Limitations Stated:** Comprehensive - methodology documentation notes limitations
|
||||
- **Raw Data Available:** Public Use Microdata Samples (PUMS) available; restricted-access microdata available through Federal Statistical Research Data Centers
|
||||
|
||||
### Reliability Assessment
|
||||
|
||||
**Consistency:**
|
||||
- **Internal Consistency:** Strong - automated edit procedures ensure logical consistency
|
||||
- **Temporal Consistency:** Excellent - consistent methodology 2005-present; major changes documented
|
||||
- **Cross-source Consistency:** Good agreement with CPS, NHIS for overlapping measures; differences explained by sample design
|
||||
|
||||
**Stability:**
|
||||
- **Definition Changes:** Rare - major changes (e.g., relationship categories) phased in with documentation
|
||||
- **Methodology Changes:** Occasional improvements (e.g., 2013 CAPI instrument redesign); documented in methodology papers
|
||||
- **Series Breaks:** Clearly marked when definitions change materially (e.g., 2008 industry/occupation coding)
|
||||
|
||||
**Verification:**
|
||||
- **Independent Verification:** Academic researchers extensively validate ACS data quality; errors reported and corrected
|
||||
- **Replication Studies:** PUMS enable independent replication; Census Bureau publishes design factors for complex variance estimation
|
||||
- **Audit Results:** Office of Inspector General audits data quality programs; findings public
|
||||
|
||||
### Accuracy Assessment
|
||||
|
||||
**Validation Evidence:**
|
||||
- **Benchmark Comparisons:** ACS estimates compared to decennial census, IRS records, Social Security records; generally excellent agreement (within sampling error)
|
||||
- **Coverage Assessments:** Coverage studies show 98%+ of housing units in sampling frame; known undercount of homeless, non-response in high-poverty areas
|
||||
- **Error Studies:** Census Bureau publishes data quality reports; content reinterview studies; coverage studies
|
||||
|
||||
**Accuracy for Different Uses:**
|
||||
- **Point Estimates:** Highly reliable for large geographies (states, large counties); MOE ±3-5%; moderate reliability for small areas (census tracts) MOE ±10-20%
|
||||
- **Trend Analysis:** Reliable for medium-term trends (3-5 years); year-to-year changes should use statistical testing (overlapping MOEs may indicate no significant change)
|
||||
- **Cross-sectional Comparison:** Reliable for geographic comparisons; use MOEs to determine statistical significance
|
||||
- **Sub-population Analysis:** Good for large subpopulations (age, sex, race); limited for intersectional analysis in small areas due to sample size
|
||||
|
||||

|
||||
|
||||
## Known Limitations and Caveats
|
||||
|
||||
### Coverage Limitations
|
||||
|
||||
**Geographic Gaps:**
|
||||
- Remote Alaska areas (some villages excluded or sampled at lower rates)
|
||||
- Homeless individuals not in shelters/group quarters (missed)
|
||||
- Institutional populations included but sample sizes small for detailed analysis
|
||||
|
||||
**Temporal Gaps:**
|
||||
- No sub-annual data (annual only)
|
||||
- 2020 data collection impacted by COVID-19 pandemic (operational changes documented)
|
||||
|
||||
**Population Exclusions:**
|
||||
- Homeless not in shelters systematically undercounted
|
||||
- Undocumented immigrants may be undercounted due to survey nonresponse
|
||||
- High-nonresponse areas (distressed urban/rural areas) have higher uncertainty
|
||||
|
||||
**Variable Gaps:**
|
||||
- Social capital measures limited (no direct questions on social networks, loneliness, community engagement)
|
||||
- Mental health not covered (use NHIS or BRFSS)
|
||||
- Detailed time use beyond commuting not available (use ATUS)
|
||||
|
||||
### Methodological Limitations
|
||||
|
||||
**Sampling Limitations:**
|
||||
- Small-area estimates (census tracts, block groups) have high sampling error (MOE ±15-30% for rare characteristics)
|
||||
- Multi-year aggregation (5-year estimates) necessary for small areas but obscures recent changes
|
||||
- Rare populations (small race/ethnic groups, disabilities in small areas) have suppressed data or wide MOEs
|
||||
|
||||
**Measurement Limitations:**
|
||||
- Self-reported income and housing values subject to measurement error (non-response, rounding, underreporting)
|
||||
- Living arrangements measured at survey date (single cross-section doesn't capture fluidity)
|
||||
- Commute times self-reported (may differ from actual travel times)
|
||||
- Internet access self-reported (may not reflect quality/speed of connection)
|
||||
|
||||
**Processing Limitations:**
|
||||
- Missing data imputed (introduces uncertainty beyond sampling error)
|
||||
- Weighting to population controls (assumes nonrespondents similar to respondents in weighting class)
|
||||
- Disclosure avoidance procedures may introduce small amounts of noise in published estimates
|
||||
|
||||
### Comparability Limitations
|
||||
|
||||
**Cross-national Comparability:**
|
||||
- Not applicable (US-only data source)
|
||||
|
||||
**Temporal Comparability:**
|
||||
- Methodology generally consistent 2005-present
|
||||
- Question wording changes rare but documented (e.g., 2008 industry/occupation recode, 2019 relationship categories expanded)
|
||||
- 2020 operational changes due to COVID-19 (documented; comparison to prior years should note this)
|
||||
|
||||
**Geographic Comparability:**
|
||||
- Census tract boundaries change every 10 years (use tract equivalency files for time series)
|
||||
- Some geographies not comparable across years (places incorporate/annex/disincorporate)
|
||||
|
||||
**Sub-group Comparability:**
|
||||
- Small sample sizes for detailed subgroups in small areas result in data suppression or unreliable estimates
|
||||
- Intersectional analysis limited (e.g., living alone by age by race in census tracts often unavailable)
|
||||
|
||||
### Usage Caveats
|
||||
|
||||
**Inappropriate Uses:**
|
||||
1. **DO NOT use 1-year estimates for small areas** - use 5-year estimates for census tracts/block groups (1-year not available)
|
||||
2. **DO NOT compare overlapping multi-year estimates** - 2017-2021 and 2018-2022 share 4 years of data; not independent comparisons
|
||||
3. **DO NOT ignore margins of error** - overlapping MOEs = no statistically significant difference
|
||||
4. **DO NOT use for individual-level inference** - aggregated data; ecological fallacy risk
|
||||
|
||||
**Ecological Fallacy Risks:**
|
||||
- Census tract-level associations don't necessarily hold at individual level
|
||||
- Example: Tracts with high % living alone may not have higher individual loneliness if those living alone are well-connected
|
||||
|
||||
**Correlation vs. Causation:**
|
||||
- Cross-sectional data; cannot infer causation
|
||||
- Appropriate for descriptive analysis, hypothesis generation
|
||||
- Causal inference requires longitudinal designs, individual-level data
|
||||
|
||||
**Statistical Significance:**
|
||||
- Always use MOEs to test for significance before claiming differences
|
||||

## Recommended Use Cases
|
||||
|
||||
### Ideal Applications
|
||||
|
||||
**Research Questions Well-Suited:**
|
||||
1. "Which US communities have the highest rates of living alone (structural isolation)?"
|
||||
2. "Where are the time poverty hotspots (long commute + low income areas)?"
|
||||
3. "How has the digital divide changed across US communities 2010-2022?"
|
||||
4. "What is the relationship between living alone and housing costs at the community level?"
|
||||
5. "Which neighborhoods have experienced increases in single-person households over the past decade?"
|
||||
|
||||
**Analysis Types Supported:**
|
||||
- Descriptive statistics (rates, medians, percentiles by geography)
|
||||
- Trend analysis (time series by community)
|
||||
- Geographic comparison (cross-sectional comparison of communities)
|
||||
- Correlation analysis (relationships between indicators - ecological level)
|
||||
- Spatial analysis (mapping, clustering, hot spot detection)
|
||||
|
||||
### Appropriate Contexts
|
||||
|
||||
**Geographic Contexts:**
|
||||
- National analysis (US-wide patterns)
|
||||
- State comparisons
|
||||
- Metropolitan area analysis
|
||||
- County-level analysis
|
||||
- Census tract/block group analysis (use 5-year estimates)
|
||||
- Custom geographies (aggregated from tracts)
|
||||
|
||||
**Temporal Contexts:**
|
||||
- Long-term trends (2005-present)
|
||||
- Medium-term trends (5-10 years most reliable)
|
||||
- Recent snapshot (use 1-year for large areas, 5-year for small areas)
|
||||
|
||||
**Subject Contexts:**
|
||||
- Social isolation and connection (living arrangements)
|
||||
- Time poverty and commuting burden
|
||||
- Digital divide and internet access
|
||||
- Housing affordability and security
|
||||
- Economic wellbeing and employment
|
||||
- Community demographic change
|
||||
|
||||
### Use Warnings
|
||||
|
||||
**Avoid Using This Source For:**
|
||||
1. **Individual-level analysis** → Use PUMS microdata if available, or individual-level surveys (NHIS, BRFSS, ATUS)
|
||||
2. **Real-time monitoring** → Use administrative data, real-time surveys
|
||||
3. **Causal inference** → Use longitudinal panel data, quasi-experimental designs
|
||||
4. **Small populations in small areas** → Data suppressed or unreliable; use larger geographic aggregation
|
||||
5. **Sub-annual trends** → Annual data only; use monthly surveys (CPS) for sub-annual trends
|
||||
|
||||
**Recommended Alternatives For:**
|
||||
- Individual-level analysis → PUMS microdata (larger sampling error but individual records)
|
||||
- More timely data → Current Population Survey (state-level, monthly)
|
||||
- Social capital measures → General Social Survey, Behavioral Risk Factor Surveillance System
|
||||
- Detailed time use → American Time Use Survey
|
||||
- Longitudinal analysis → Panel Study of Income Dynamics (PSID), Survey of Income and Program Participation (SIPP)

## Cataloger Notes
|
||||
|
||||
**Internal Notes:**
|
||||
- CRITICAL source for US social wellbeing measurement; authoritative and most granular public data
|
||||
- API well-documented; rate limits low (500/day) but manageable with proper throttling
|
||||
- Margins of error essential for statistical testing - must include in analysis
|
||||
- 5-year estimates necessary for census tract-level analysis (1-year not available)
|
||||
- Living alone (B11001_008E) and commute times (B08303) are key structural social isolation/time poverty indicators
|
||||
- Digital divide measures (B28002, B28003) critical for opportunity access analysis
|
||||
|
||||
**To Do:**
|
||||
- [x] Create comprehensive source.md
|
||||
- [ ] Create update.ts script with API key handling and rate limiting
|
||||
- [ ] Test API access with sample queries
|
||||
- [ ] Document key variable combinations for social wellbeing analysis
|
||||
- [ ] Cross-reference with Substrate Problems and Solutions once defined
|
||||
|
||||
**Questions for Review:**
|
||||
- Should we pre-fetch specific indicator tables or fetch on-demand?
|
||||
- How to handle 1-year vs 5-year estimates (separate source entries or version parameter)?
|
||||
- What geographic granularity to prioritize (tracts, counties, states)?

# DS-00007 Setup Notes
|
||||
|
||||
## Current Status: API Testing Required
|
||||
|
||||
The data source has been created with comprehensive documentation and update script, but **API testing revealed the series IDs need verification**.
|
||||
|
||||
## Issue Discovered
|
||||
|
||||
When testing the BLS API v2 with series ID `JTS00000000QUR` (quit rate), the API returns:
|
||||
```
|
||||
"Series does not exist for Series JTS00000000QUR"
|
||||
```
|
||||
|
||||
## Possible Causes
|
||||
|
||||
1. **Series ID Format Change (October 2020)**: BLS changed JOLTS series code structure on October 6, 2020 to support establishment size class data and future state/MSA data. The old format `JTS00000000QUR` may no longer be valid.
|
||||
|
||||
2. **FRED vs. BLS Series IDs**: FRED uses different series IDs (e.g., `JTSJOR`) that don't match BLS API series IDs directly.
|
||||
|
||||
3. **API Endpoint Issue**: The BLS API v2 may not support JOLTS series, or requires different authentication/parameters.
|
||||
|
||||
## Investigation Needed
|
||||
|
||||
### Option 1: Find Correct BLS Series IDs
|
||||
|
||||
Check the official BLS JOLTS series changes page:
|
||||
- https://www.bls.gov/jlt/jlt_series_changes.htm
|
||||
- Look for the new series ID format post-2020
|
||||
- Test with curl to verify series exists
|
||||
|
||||
Example test command:
|
||||
```bash
|
||||
curl -X POST 'https://api.bls.gov/publicAPI/v2/timeseries/data/' \
|
||||
-H 'Content-Type: application/json' \
|
||||
-d '{"seriesid":["NEW_SERIES_ID"],"startyear":"2023","endyear":"2024"}'
|
||||
```
|
||||
|
||||
### Option 2: Use FRED API Instead
|
||||
|
||||
FRED provides JOLTS data with simpler API and well-documented series IDs:
|
||||
- FRED API: https://api.stlouisfed.org/fred/series/observations
|
||||
- Series IDs confirmed working:
|
||||
- `JTSJOR` - Job Openings Rate
|
||||
- `JTSQUR` - Quit Rate
|
||||
- `JTSHIR` - Hire Rate
|
||||
- `JTSLD` - Layoff/Discharge Rate
|
||||
- `JTSTSR` - Total Separations Rate
|
||||
|
||||
FRED advantage: Already have working update script in DS-00004 (FRED Economic Wellbeing) that can be adapted.
|
||||
|
||||
### Option 3: Bulk Download from BLS
|
||||
|
||||
BLS provides bulk data downloads:
|
||||
- https://download.bls.gov/pub/time.series/jt/
|
||||
- Parse tab-delimited files directly
|
||||
- No API rate limits
|
||||
- Requires parsing file format
|
||||
|
||||
## Recommended Next Steps
|
||||
|
||||
1. **Quick Win**: Modify update.ts to use FRED API instead of BLS API
|
||||
- Copy pattern from DS-00004 FRED updater
|
||||
- Use FRED series IDs (JTSQUR, JTSJOR, JTSHIR, JTSLD, JTSTSR)
|
||||
- FRED_API_KEY already available in environment
|
||||
|
||||
2. **Long-term**: Research correct BLS JOLTS series IDs and document
|
||||
- Contact BLS support if needed
|
||||
- Update documentation with correct series IDs
|
||||
- Keep BLS as primary source, FRED as backup
|
||||
|
||||
3. **Alternative**: Use BLS bulk download parser
|
||||
- More complex implementation
|
||||
- No rate limits
|
||||
- Always most recent data
|
||||
|
||||
## Files Created
|
||||
|
||||
- ✅ `source.md` - Comprehensive 800+ line documentation (COMPLETE)
|
||||
- ✅ `update.ts` - TypeScript/bun update script (NEEDS SERIES ID FIX)
|
||||
- ✅ `data/README.md` - Data directory documentation (COMPLETE)
|
||||
- ⚠️ API testing incomplete - series IDs need correction
|
||||
|
||||
## Series IDs to Verify
|
||||
|
||||
| Indicator | Old Format (Pre-2020?) | Status | Notes |
|
||||
|-----------|------------------------|--------|-------|
|
||||
| Quit Rate | JTS00000000QUR | ❌ Not found | Need new format |
|
||||
| Job Openings Rate | JTS00000000JOR | ❌ Not found | Need new format |
|
||||
| Hire Rate | JTS00000000HIR | ❌ Not found | Need new format |
|
||||
| Layoff/Discharge Rate | JTS00000000LDR | ❌ Not found | Need new format |
|
||||
| Total Separations Rate | JTS00000000TSR | ❌ Not found | Need new format |
|
||||
|
||||
## FRED Alternative (Known Working)
|
||||
|
||||
| Indicator | FRED Series ID | Status |
|
||||
|-----------|----------------|--------|
|
||||
| Quit Rate | JTSQUR | ✅ Available via FRED API |
|
||||
| Job Openings Rate | JTSJOR | ✅ Available via FRED API |
|
||||
| Hire Rate | JTSHIR | ✅ Available via FRED API |
|
||||
| Layoff/Discharge Rate | JTSLD | ✅ Available via FRED API |
|
||||
| Total Separations Rate | JTSTSR | ✅ Available via FRED API |
|
||||
|
||||
## Decision Required
|
||||
|
||||
**Should we:**
|
||||
A) Fix BLS series IDs (maintain primary source authority)
|
||||
B) Switch to FRED API (faster implementation, already working in DS-00004)
|
||||
C) Use both (BLS primary, FRED fallback)
|
||||
|
||||
## Time Estimate
|
||||
|
||||
- Option A (Fix BLS): 30-60 minutes research + testing
|
||||
- Option B (Switch to FRED): 15-20 minutes (copy existing pattern)
|
||||
- Option C (Both): 45-75 minutes

# JOLTS Data Directory
|
||||
|
||||
This directory contains JOLTS (Job Openings and Labor Turnover Survey) data from the Bureau of Labor Statistics.
|
||||
|
||||
## Files
|
||||
|
||||
- **latest.json** - Raw API response data (JSON format)
|
||||
- **latest.txt** - Transformed data in Substrate pipe-delimited format
|
||||
- **permission-to-quit-index.txt** - Analysis summary of quit rate trends and interpretation
|
||||
|
||||
## Permission to Quit Index
|
||||
|
||||
The quit rate is the **most important indicator** in this data source. It measures worker agency and economic confidence:
|
||||
|
||||
- **High quit rate (≥2.5%)** = Workers feel empowered, have options, can leave bad jobs
|
||||
- **Moderate quit rate (2.0-2.5%)** = Some worker confidence, but many may feel trapped
|
||||
- **Low quit rate (<2.0%)** = Workers feel trapped, lack confidence to quit even unsatisfying jobs
|
||||
|
||||
## Update Schedule
|
||||
|
||||
Data is updated monthly, approximately 6 weeks after the reference month (around the 10th of month+2).
|
||||
|
||||
Example: September data is typically published around November 10.
|
||||
|
||||
## Data Format
|
||||
|
||||
Pipe-delimited format:
|
||||
```
|
||||
RECORD ID | SERIES ID | SERIES NAME | DATE | PERIOD NAME | VALUE | FREQUENCY | PRIORITY | INTERPRETATION | DESCRIPTION
|
||||
```
|
||||
|
||||
## Series IDs
|
||||
|
||||
1. **JTS00000000QUR** - Quit Rate (Priority 1 - MOST CRITICAL)
|
||||
2. **JTS00000000JOR** - Job Openings Rate (Priority 2)
|
||||
3. **JTS00000000HIR** - Hire Rate (Priority 3)
|
||||
4. **JTS00000000LDR** - Layoff/Discharge Rate (Priority 4)
|
||||
5. **JTS00000000TSR** - Total Separations Rate (Priority 5)
|
||||
|
||||
All series are seasonally adjusted, total nonfarm.

### Content Boundaries
|
||||
|
||||
**What This Source IS:**
|
||||
- **Premier source for worker agency measurement** via quit rate ("Permission to Quit Index")
|
||||
- Gold-standard data for labor market dynamics (quits, hires, openings, layoffs)
|
||||
- Best indicator of worker confidence and economic empowerment
|
||||
- Reveals hidden economic distress traditional metrics miss (low quits during expansion = trapped workers)
|
||||
- Leading indicator of wage growth (quits force employers to raise wages)
|
||||
|
||||
**What This Source IS NOT:**
|
||||
- NOT individual-level data (aggregated establishment data; no worker microdata)
|
||||
- NOT real-time (6-week publication lag; not suitable for daily/weekly tracking)
|
||||
- NOT international (U.S. only; limited comparability with other countries)
|
||||
- NOT reasons for quits (doesn't distinguish better opportunity vs. dissatisfaction vs. retirement)
|
||||
- NOT comprehensive wellbeing (measures labor market behavior, not happiness, health, meaning)
|
||||
|
||||
**Comparison with Similar Sources:**
|
||||
|
||||
| Source | Advantages Over JOLTS | Disadvantages vs. JOLTS |
|
||||
|--------|----------------------|-------------------------|
|
||||
| Current Population Survey (CPS) | Individual-level microdata; demographic breakdowns; reasons for job changes | No job openings data; less timely; retrospective (recall bias) |
|
||||
| Current Employment Statistics (CES) | Weekly updates; payroll-based (no survey non-response); longer history (1939+) | No quits/layoffs/openings; only net employment change |
|
||||
| ADP National Employment Report | More timely (weekly); private sector payroll data | No quits/layoffs/openings; proprietary; no government/nonprofit |
|
||||
| OECD Job Retention Data | International comparability | Limited U.S. granularity; longer lag; no quit rate |
|
||||
|
||||
**JOLTS Unique Contribution:**
|
||||
- **ONLY source measuring quit rate nationally** - no other federal survey tracks worker-initiated separations
|
||||
- Simultaneous tracking of demand (openings), supply (quits), and flow (hires)
|
||||
- Distinguishes quits (worker agency) from layoffs (employer agency) - critical for wellbeing

## Collection Development Policy Fit
|
||||
|
||||
### Relevance Assessment
|
||||
|
||||
**Substrate Mission Alignment:**
|
||||
- **Human Progress Focus:** Worker agency and economic empowerment central to human flourishing; quit rate reveals hidden dimensions of economic wellbeing (confidence, options, power)
|
||||
- **Problem-Solution Connection:**
|
||||
- Links to Problems: Worker precarity, economic insecurity, lack of economic mobility, wage stagnation, involuntary job lock-in
|
||||
- Links to Solutions: Worker empowerment policies, labor market interventions, unemployment insurance, job training programs, minimum wage policy
|
||||
- **Evidence Quality:** Gold-standard federal statistics; peer-reviewed methodology; 25+ years consistent data; unique measurement of worker agency
|
||||
|
||||
**Collection Priorities Match:**
|
||||
- **Priority Level:** CRITICAL - essential source for labor market wellbeing and worker agency measurement
|
||||
- **Uniqueness:** ONLY federal survey measuring quit rate; no alternative source for worker-initiated separation data
|
||||
- **Comprehensiveness:** Fills critical gap for economic wellbeing - reveals worker confidence and agency traditional employment metrics miss
|
||||
|
||||
### Comparison with Holdings
|
||||
|
||||
**Overlapping Sources:**
|
||||
- DS-00004 (FRED Economic Wellbeing) - some overlapping employment indicators (unemployment rates)
|
||||
- DS-00006 (Census ACS Social Wellbeing) - employment status, occupation data
|
||||
|
||||
**Unique Contribution:**
|
||||
- **Quit Rate ("Permission to Quit Index")** - not available in any other Substrate source
|
||||
- Labor market dynamics (hires, openings, separations) with establishment-based measurement
|
||||
- Distinguishes voluntary (quits) from involuntary (layoffs) separations - critical for wellbeing
|
||||
- Monthly frequency with ~6 week lag (more timely than annual Census data, more detailed than weekly employment reports)
|
||||
|
||||
**Preferred Use Cases:**
|
||||
- Measuring worker agency and economic confidence over time
|
||||
- Tracking "Permission to Quit" as wellbeing indicator
|
||||
- Analyzing labor market dynamism (hiring, turnover, churn)
|
||||
- Understanding employer vs. worker-initiated separations
|
||||
- Detecting hidden economic distress (low quits during expansion = trapped workers)
|
||||
- Leading indicator of wage growth (quits force wage increases)

## Source Evaluation Narrative
|
||||
|
||||
### Methodological Assessment
|
||||
|
||||
**Data Collection Methodology:**
|
||||
|
||||
**Sampling Design:**
|
||||
- **Method:** Stratified random sample of establishments; probability-based sampling
|
||||
- **Sample Size:** 21,000 establishments surveyed monthly (representing ~9.4 million establishments)
|
||||
- **Sampling Frame:** Quarterly Census of Employment and Wages (QCEW) universe of establishments
|
||||
- **Stratification:** Three-dimensional stratification - Industry (NAICS), Geographic region (state, MSA), Establishment size (employment)
|
||||
- **Weighting:** Sample weights adjust for non-response, benchmark to QCEW employment totals, calibrated to match Current Employment Statistics (CES) employment levels
|
||||
|
||||
**Data Collection Instruments:**
|
||||
- **Instrument Type:** Establishment survey form (electronic and paper)
|
||||
- **Validation:** Computer-assisted validation during data entry; BLS staff review anomalies
|
||||
- **Question Wording:** Standardized since 2000; clear definitions (quit = employee-initiated separation, layoff = employer-initiated for business reasons)
|
||||
- **Mode:** Online survey (preferred), fax, phone, mail; multi-mode to maximize response
|
||||
|
||||
**Quality Control Procedures:**
|
||||
- **Field Supervision:** BLS National Office oversight; regional BLS offices provide support
|
||||
- **Validation Rules:** Automated edits check for consistency (e.g., hires + beginning employment = ending employment + separations); extreme values flagged
|
||||
- **Consistency Checks:** Cross-series validation (quits + layoffs + other separations = total separations); benchmark to CES employment
|
||||
- **Verification:** Non-response follow-up; large establishment data verified by phone
|
||||
- **Outlier Treatment:** Extreme values reviewed by analysts; establishment contacted if necessary; statistical outlier detection algorithms
|
||||
|
||||
**Error Characteristics:**
|
||||
- **Sampling Error:** Standard errors published quarterly for national estimates; quit rate typically ±0.1-0.2 percentage points (95% CI)
|
||||
- **Non-sampling Error:** Unit non-response (~30% monthly; addressed by weighting adjustments), item non-response (imputation used), measurement error (definitional ambiguity - retirements classified as quits or other separations depending on establishment reporting)
|
||||
- **Known Biases:** Small establishments slightly underrepresented (harder to contact, higher non-response); seasonal patterns in some industries may not fully adjust
|
||||
- **Accuracy Bounds:** National estimates highly accurate (large sample, careful weighting); state/industry/size breakdowns have larger margins of error
|
||||
|
||||
**Methodology Documentation:**
|
||||
- **Transparency Level:** 5/5 (Comprehensive) - detailed methodology handbook, technical notes, sampling documentation
|
||||
- **Documentation URL:** https://www.bls.gov/jlt/jlt_handbook.htm (JOLTS Handbook of Methods)
|
||||
- **Peer Review Status:** Federal statistical standards review; academic peer review; methodology published in Monthly Labor Review
|
||||
- **Reproducibility:** High - published methodology allows replication; microdata available through Federal Statistical Research Data Centers (FSRDC) for approved researchers
|
||||
|
||||

||||
|
||||
**Update Characteristics:**
|
||||
- **Update Frequency:** Monthly (data for month M published approximately 6 weeks after month-end, around the 10th of month M+2)
|
||||
- **Update Reliability:** Highly consistent; follows published schedule (Economic News Release calendar)
|
||||
- **Update Notification:** Email subscription available; RSS feed; release calendar published in advance
|
||||
- **Last Updated:** 2025-10-27 (catalog entry date)
|
||||
|
||||
**Timeliness:**
|
||||
- **Collection to Publication Lag:**
|
||||
- Survey reference period: Last business day of month
|
||||
- Collection period: First 3 weeks of following month
|
||||
- Processing and review: ~3 weeks
|
||||
- Publication: ~6 weeks after reference month (e.g., September data published ~November 10)
|
||||
- **Factors Affecting Timeliness:** Non-response follow-up, data quality review, seasonal adjustment calculations, holiday schedules
|
||||
- **Historical Timeliness:** Consistent; rare delays (government shutdowns occasionally delayed releases by 1-2 weeks)
|
||||
|
||||
**Currency for Different Uses:**
|
||||
- **Real-time Analysis:** Not suitable (6-week lag); use for monthly/quarterly trend analysis
|
||||
- **Recent Trends:** Excellent for tracking 3-6 month trends in labor market dynamics
|
||||
- **Historical Research:** Excellent - 25 years (December 2000-present) of consistent monthly data
|
||||
|
||||
### Objectivity Assessment
|
||||
|
||||
**Potential Biases:**
|
||||
|
||||
**Political Bias:**
|
||||
- **Government Influence:** BLS independence protected by statute; data published regardless of political implications; Commissioner serves fixed term
|
||||
- **Editorial Stance:** BLS mission is objective statistical reporting, not policy advocacy; data presented without political interpretation
|
||||
- **Political Pressure:** Federal statistical standards (OMB Statistical Policy Directives) protect against interference; rare instances of political criticism of data, but methodology and results not altered
|
||||
|
||||
**Commercial Bias:**
|
||||
- **Funding Sources:** Federal appropriations; independent statistical mission (no commercial funding or influence)
|
||||
- **Advertising Influence:** Not applicable (non-commercial government agency)
|
||||
- **Proprietary Interests:** None - public service mission; data free and public domain
|
||||
|
||||
**Cultural/Social Bias:**
|
||||
- **Geographic Bias:** U.S.-centric; no international coverage
|
||||
- **Social Perspective:** Establishment-based (employer perspective) rather than worker perspective; may miss informal economy, self-employment transitions
|
||||
- **Language Bias:** English primary language; establishments with non-English speaking staff may have response challenges
|
||||
- **Selection Bias:** Nonfarm establishments only; excludes agricultural workers, self-employed, gig economy workers without employees, private household workers
|
||||
|
||||
**Transparency:**
|
||||
- **Bias Disclosure:** BLS acknowledges survey limitations in methodology documentation (non-response, small establishment underrepresentation)
|
||||
- **Limitations Stated:** Technical notes specify coverage exclusions, sampling error ranges, revision policy
|
||||
- **Raw Data Available:** Microdata available through Federal Statistical Research Data Centers (FSRDC) for approved researchers (anonymized to protect establishment confidentiality)
|
||||
|
||||
### Reliability Assessment
|
||||
|
||||
**Consistency:**
|
||||
- **Internal Consistency:** High - automated consistency checks; quits + layoffs + other = total separations; identities verified
|
||||
- **Temporal Consistency:** Excellent - methodology unchanged since 2000; seasonal adjustment revised annually using consistent procedures
|
||||
- **Cross-source Consistency:** Good agreement with CPS job-to-job transitions (different perspective but correlated trends); CES employment benchmarked to JOLTS
|
||||
|
||||
**Stability:**
|
||||
- **Definition Changes:** None - definitions stable since inception (December 2000); quit, layoff, hire definitions unchanged
|
||||
- **Methodology Changes:** Minimal - sample refreshed periodically; weighting updated to reflect QCEW benchmarks; seasonal adjustment procedures updated annually (standard practice)
|
||||
- **Series Breaks:** None - continuous time series December 2000-present with consistent methodology
|
||||
|
||||
**Verification:**
|
||||
- **Independent Verification:** Federal Reserve uses JOLTS data for policy analysis; academic researchers validate trends; media scrutinizes high-profile releases
|
||||
- **Replication Studies:** Academic papers replicate JOLTS findings using microdata from FSRDC; consistency with CPS job transitions validated in research
|
||||
- **Audit Results:** BLS Office of Inspector General audits; GAO reviews; no significant issues identified
|
||||
|
||||
### Accuracy Assessment
|
||||
|
||||
**Validation Evidence:**
|
||||
- **Benchmark Comparisons:** JOLTS employment levels benchmarked to Quarterly Census of Employment and Wages (QCEW); hires and separations validated against CPS job transitions (worker-reported)
|
||||
- **Coverage Assessments:** Sample represents 99%+ of nonfarm payroll employment (by weighting to QCEW); coverage documented in methodology handbook
|
||||
- **Error Studies:** BLS publishes standard errors quarterly for national estimates; state estimates have larger margins of error (published in technical notes)
|
||||
|
||||
**Accuracy for Different Uses:**
|
||||
- **Point Estimates:** Highly accurate for national rates (quit rate ±0.1-0.2 pp at 95% CI); industry/state estimates have larger margins of error (documented in releases)
|
||||
- **Trend Analysis:** Excellent for detecting trends (6+ month trends generally outside margin of error); month-to-month volatility within statistical noise
|
||||
- **Cross-sectional Comparison:** Reliable for comparing industries, regions, size classes (if margins of error considered); national comparisons most reliable
|
||||
- **Sub-population Analysis:** Industry breakdowns (2-digit NAICS) reliable; size class breakdowns (establishment size) reliable; state/MSA estimates less reliable (larger standard errors)
|
||||
|

|
||||
## Known Limitations and Caveats
|
||||
|
||||
### Coverage Limitations
|
||||
|
||||
**Geographic Gaps:**
|
||||
- National and regional data highly reliable; state-level data available but larger margins of error
|
||||
- Metropolitan Statistical Area (MSA) data limited to job openings only (~50 MSAs); no MSA data for quits, layoffs, hires
|
||||
- County-level data not available
|
||||
- U.S. territories (Puerto Rico, Guam, etc.) not covered
|
||||
|
||||
**Temporal Gaps:**
|
||||
- Historical data begins December 2000 (no earlier data available via JOLTS)
|
||||
- For pre-2000 analysis, alternative sources needed (CPS job turnover supplements - irregular; CES net employment change only)
|
||||
- 6-week publication lag limits real-time analysis
|
||||
|
||||
**Population Exclusions:**
|
||||
- **Farm workers:** Agricultural establishments excluded (outside JOLTS scope)
|
||||
- **Self-employed:** Individuals with no employees excluded (JOLTS surveys establishments, not self-employed)
|
||||
- **Private household workers:** Domestic workers employed by households excluded
|
||||
- **Gig economy workers:** Independent contractors, platform workers (Uber, DoorDash) not covered unless establishment employees
|
||||
- **Informal economy:** Under-the-table work, informal arrangements not measured
|
||||
|
||||
**Variable Gaps:**
|
||||
- **No reasons for quits:** JOLTS doesn't ask why employees quit (better opportunity vs. dissatisfaction vs. retirement vs. family reasons)
|
||||
- **No demographic breakdowns:** No data by age, race, gender, education (establishment survey, not individual survey)
|
||||
- **No wage data:** Doesn't track wages of quitters vs. stayers; no wage growth for job changers
|
||||
- **No duration data:** Doesn't track tenure of quitters (recent hires vs. long-tenured employees)
|
||||
- **No destination data:** Doesn't track where quitters go (new job vs. unemployment vs. out of labor force)
|
||||
|
||||
### Methodological Limitations
|
||||
|
||||
**Sampling Limitations:**
|
||||
- Establishment survey (employer-reported) may differ from worker-reported separations (CPS)
|
||||
- Small establishments underrepresented in sample (harder to contact, higher non-response)
|
||||
- New establishments enter sample with lag (QCEW sampling frame updates quarterly)
|
||||
- ~30% unit non-response rate (addressed by weighting, but potential for non-response bias if non-responders differ systematically)
|
||||
|
||||
**Measurement Limitations:**
|
||||
- **Definitional ambiguity:** Retirement classified inconsistently (some establishments report as quit, others as "other separation")
|
||||
- **Layoff vs. quit gray area:** Encouraged resignations, forced retirements may be misclassified
|
||||
- **Timing:** Separations reported for last business day of month; within-month turnover not captured
|
||||
- **Establishment-level reporting:** Large establishments may have imprecise records for job openings, separations (HR data systems vary)
|
||||
|
||||
**Processing Limitations:**
|
||||
- Seasonal adjustment can obscure actual values (seasonally adjusted vs. not seasonally adjusted)
|
||||
- Revisions occur (preliminary → revised data); typically small revisions but occasionally significant
|
||||
- Imputation for item non-response (if establishment skips question, value imputed from similar establishments)
|
||||
- Weighting adjustments may not fully correct for non-response bias if non-responders systematically different
|
||||
|
||||
### Comparability Limitations
|
||||
|
||||
**Cross-national Comparability:**
|
||||
- U.S.-specific survey; limited international comparability
|
||||
- OECD tracks job retention/separation rates for some countries, but methodology differs (not directly comparable)
|
||||
- EU Labour Force Survey measures job changes, but definitions differ from JOLTS
|
||||
- International comparisons require careful definitional alignment (OECD harmonized data preferred for cross-country analysis)
|
||||
|
||||
**Temporal Comparability:**
|
||||
- JOLTS data only available December 2000-present (25 years)
|
||||
- No historical data pre-2000 for quit rate, job openings, hires (CPS job turnover supplements 1970s-1990s irregular and not comparable)
|
||||
- Methodology stable since 2000, so time series highly comparable within JOLTS era
|
||||
|
||||
**Sub-group Comparability:**
|
||||
- Industry comparisons reliable (2-digit NAICS level)
|
||||
- Size class comparisons reliable (1-49 employees, 50-249, 250+, etc.)
|
||||
- State comparisons less reliable (larger standard errors)
|
||||
- No demographic comparisons available (no age, race, gender, education data)
|
||||
|
||||
### Usage Caveats
|
||||
|
||||
**Inappropriate Uses:**
|
||||
1. **DO NOT use for individual-level analysis** - establishment survey; no worker microdata; use CPS microdata for individual job transitions
|
||||
2. **DO NOT assume reasons for quits** - JOLTS measures quit rate, not reasons; use CPS job change supplements or qualitative surveys for reasons
|
||||
3. **DO NOT use for real-time tracking** - 6-week lag; use weekly unemployment claims for more timely labor market distress signals
|
||||
4. **DO NOT compare across countries without harmonization** - U.S.-specific methodology; use OECD harmonized data for international comparisons
|
||||
5. **DO NOT use for demographic analysis** - no age/race/gender/education breakdowns; use CPS for demographic labor market analysis
|
||||
6. **DO NOT ignore sampling error** - state/industry estimates have margins of error; small month-to-month changes may be statistical noise
|
||||
|
||||
**Ecological Fallacy Risks:**
|
||||
- National quit rate doesn't apply uniformly across all industries, regions, demographics
|
||||
- Example: National quit rate 2.3% doesn't mean all workers have 2.3% probability of quitting (varies by industry - leisure/hospitality higher, government lower)
|
||||
- Aggregate trends may mask important sub-group variations (low-wage workers may have different quit patterns than high-wage)
|
||||
|
||||
**Correlation vs. Causation:**
|
||||
- JOLTS data appropriate for tracking labor market dynamics over time
|
||||
- Correlations (e.g., high quit rate and wage growth) suggestive but not causal
|
||||
- Causal inference requires careful research design (natural experiments, econometric techniques)
|
||||
- Example: Quit rate rising during economic expansion - does confidence cause quits, or do job opportunities cause quits? (Likely both, but disentangling requires more sophisticated analysis)
|
||||

||||
## Recommended Use Cases
|
||||
|
||||
### Ideal Applications
|
||||
|
||||
**Research Questions Well-Suited:**
|
||||
1. **"How has worker agency evolved over the past 25 years?"** (quit rate as Permission to Quit Index)
|
||||
2. **"Are workers more confident in the current economy compared to previous recoveries?"** (quit rate trends across business cycles)
|
||||
3. **"Is there a relationship between job openings and quit rates?"** (opportunity and worker behavior)
|
||||
4. **"How do layoffs and quits respond to recessions differently?"** (employer vs. worker-initiated separations during downturns)
|
||||
5. **"Which industries have the highest labor turnover and what does that reveal about job quality?"** (industry-level quit and layoff rates)
|
||||
6. **"Is low quit rate during economic expansion a sign of hidden worker desperation?"** (Permission to Quit Index as wellbeing signal)
|
||||
|
||||
**Analysis Types Supported:**
|
||||
- Descriptive statistics (trends, levels, distributions across industries/regions)
|
||||
- Time series analysis (business cycle patterns, seasonal patterns, trends)
|
||||
- Correlation analysis (quit rate vs. wage growth, job openings vs. unemployment)
|
||||
- Event studies (impact of policy changes, economic shocks on labor market dynamics)
|
||||
- Comparative analysis (industry differences, size class differences, regional differences)
|
||||
|
||||
### Appropriate Contexts
|
||||
|
||||
**Geographic Contexts:**
|
||||
- United States national-level analysis (highest reliability)
|
||||
- Regional analysis (4 Census regions - Northeast, Midwest, South, West)
|
||||
- State-level analysis (larger margins of error; use with caution for small states)
|
||||
- Metropolitan Statistical Area analysis for job openings only (~50 MSAs)
|
||||
|
||||
**Temporal Contexts:**
|
||||
- December 2000-present (25 years of consistent data)
|
||||
- Business cycle analysis (2001 recession, Great Recession, COVID-19 recession, recoveries)
|
||||
- Monthly/quarterly trends (lag means not suitable for real-time, but good for recent trends)
|
||||
- Historical research within JOLTS era (no pre-2000 comparable data)
|
||||
|
||||
**Subject Contexts:**
|
||||
- **Worker agency and economic confidence** (quit rate as Permission to Quit Index)
|
||||
- Labor market dynamics and churn (hires, separations, turnover)
|
||||
- Job opportunity and labor demand (job openings rate)
|
||||
- Economic security (layoff rates, involuntary separations)
|
||||
- Wage growth leading indicators (quit rate precedes wage increases)
|
||||
- Labor market tightness (ratio of job openings to unemployment)
|
||||
|
||||
### Use Warnings
|
||||
|
||||
**Avoid Using This Source For:**
|
||||
1. **Individual-level job transitions** → Use CPS microdata (reasons for job changes, demographics)
|
||||
2. **Real-time labor market monitoring** → Use weekly unemployment claims, monthly CES employment
|
||||
3. **International comparisons** → Use OECD Job Retention data, EU Labour Force Survey
|
||||
4. **Demographic labor market analysis** → Use CPS (age, race, gender, education breakdowns)
|
||||
5. **Wage analysis** → Use CPS, CES Average Hourly Earnings, Occupational Employment Statistics
|
||||
6. **Reasons for quits** → Use CPS job change supplements, qualitative surveys (Pew Research, Gallup)
|
||||
7. **Gig economy, self-employment** → Use CPS Alternative Work Arrangements supplement, Freelancers Union surveys
|
||||
|
||||
**Recommended Alternatives For:**
|
||||
- Individual-level analysis → Current Population Survey (CPS) microdata
|
||||
- Real-time monitoring → Weekly unemployment claims (DOL), Monthly employment report (CES)
|
||||
- International comparisons → OECD Job Retention data, EU Labour Force Survey
|
||||
- Demographic analysis → CPS labor force statistics by demographics
|
||||
- Wage analysis → CPS Annual Social and Economic Supplement, CES Average Hourly Earnings
|
||||
- Reasons for job changes → CPS displaced worker supplements, Pew Research surveys
|
||||
- Pre-2000 turnover analysis → CPS job turnover supplements (1970s-1990s, irregular), academic historical studies

## Cataloger Notes
|
||||
|
||||
**Internal Notes:**
|
||||
- **CRITICAL SOURCE:** JOLTS quit rate is ONLY federal measurement of worker-initiated separations - irreplaceable for worker agency measurement
|
||||
- **"Permission to Quit Index" framework:** Quit rate reveals worker confidence and agency traditional metrics miss (low quits during expansion = trapped workers)
|
||||
- **Wellbeing significance:** People only quit when they have options - high quit rate = empowerment, low quit rate = desperation
|
||||
- **Leading indicator:** Quit rate precedes wage growth (quits force employers to raise wages to retain and attract)
|
||||
- API well-documented; v2 stable since 2014; free registration increases rate limits significantly (25→500 requests/day)
|
||||
- 5 core series selected for wellbeing focus (quit rate priority #1, followed by job openings, hires, layoffs, total separations)
|
||||
- Update script should fetch data monthly (scheduled around 10th of each month for previous month's data)
|
||||
|
||||
**To Do:**
|
||||
- [ ] Create update.ts script for monthly data refreshes (API v2, POST requests, rate limiting)
|
||||
- [ ] Test API with registered key (verify 500 requests/day, 50 series per request, 20 years of data)
|
||||
- [ ] Add related organizations (BLS, DOL, Federal Reserve)
|
||||
- [ ] Cross-reference with relevant Problems and Solutions
|
||||
- [ ] Monitor API for changes (subscribe to BLS developer updates)
|
||||
- [ ] Create visualization dashboard for "Permission to Quit Index" over time
|
||||
- [ ] Write blog post explaining quit rate as wellbeing indicator (link to DS-00007)
|
||||
|
||||
**Questions for Review:**
|
||||
- Should we expand beyond 5 core series to include industry-level quit rates? (Leisure/hospitality vs. government)
|
||||
- How to present "Permission to Quit Index" conceptual framework to users? (Dashboard label, blog post, explainer video?)
|
||||
- Should we calculate derived metrics? (Quit rate / unemployment rate ratio as "worker confidence index")
|
||||
- How to handle revisions? (BLS revises previous month when publishing new data; save revised data or only latest?)

* BLS JOLTS Labor Market Data Source Updater
|
||||
* Source ID: DS-00007
|
||||
* API: https://api.bls.gov/publicAPI/v2/timeseries/data/
|
||||
* Update Frequency: Monthly (~6 week lag, published around 10th of month+2)
|

*
|
||||
* PERMISSION TO QUIT INDEX - Critical Worker Wellbeing Indicator
|
||||
*
|
||||
* JOLTS Quit Rate reveals worker agency and economic confidence traditional metrics miss:
|
||||
* - People only quit when they have options and confidence
|
||||
* - High quit rate = worker empowerment, job dissatisfaction resolution, economic confidence
|
||||
* - Low quit rate during expansion = trapped workers, hidden desperation
|
||||
* - Leading indicator of wage growth (quits force employers to raise wages)
|
||||
*
|
||||
* CRITICAL JOLTS INDICATORS (Wellbeing Focus):
|
||||
* 1. JTS00000000QUR - Quit Rate (MOST IMPORTANT - "Permission to Quit Index")
|
||||
* 2. JTS00000000JOR - Job Openings Rate (opportunity availability)
|
||||
* 3. JTS00000000HIR - Hire Rate (labor market dynamism)
|
||||
* 4. JTS00000000LDR - Layoff/Discharge Rate (economic insecurity)
|
||||
* 5. JTS00000000TSR - Total Separations Rate (overall churn)

# DS-00008 — EPA Air Quality System (AQS)
|
||||
|
||||
**Environmental Health & Quality of Life Indicators**
|
||||
|
||||
## Overview
|
||||
|
||||
The EPA Air Quality System (AQS) is the **authoritative source** for ambient air quality measurements in the United States. This data source provides regulatory-grade air quality data from 4,000+ monitoring stations nationwide, with a focus on parameters most critical to human health and wellbeing.
|
||||
|
||||
**Key Insight:** Air quality is a **structural determinant of wellbeing**. You cannot "self-care" your way out of breathing toxic air. PM2.5 exposure reduces life expectancy by months to years in polluted areas. Environmental injustice: low-income communities and communities of color are disproportionately exposed.
|
||||
|
||||
## Why This Matters for Substrate
|
||||
|
||||
### Human Progress & Wellbeing Focus
|
||||
|
||||
Air quality is a fundamental structural constraint on human flourishing:
|
||||
|
||||
- **Life Expectancy:** PM2.5 reduces longevity by 1.8 years globally (Air Quality Life Index)
|
||||
- **Involuntary Exposure:** You breathe ~20,000 times per day — exposure is unavoidable
|
||||
- **Environmental Injustice:** ZIP code determines exposure — structural inequality
|
||||
- **Health Impacts:** Cardiovascular disease, respiratory disease, cognitive decline, pregnancy outcomes
|
||||
- **Quality of Life:** Restricted outdoor activity on high pollution days, healthcare costs, lost productivity
|
||||
|
||||
**Unlike individual health behaviors (diet, exercise), air quality is a collective problem requiring structural solutions.**
|
||||
|
||||
## Data Source Details
|
||||
|
||||
### Authority
|
||||
- **Organization:** U.S. Environmental Protection Agency (EPA)
|
||||
- **Office:** Office of Air Quality Planning and Standards (OAQPS)
|
||||
- **Legal Mandate:** Clean Air Act (1970, amended 1990)
|
||||
- **Data Quality:** Federal Reference/Equivalent Methods (FRM/FEM) — regulatory-grade
|
||||
- **Established:** 1971 (50+ years of air quality monitoring)
|
||||
|
||||
### Coverage
|
||||
- **Geographic:** United States (50 states, DC, territories)
|
||||
- **Temporal:** 1980-present (45+ years of validated data)
|
||||
- **Granularity:** Monitoring site level (latitude/longitude)
|
||||
- **Network Size:** 4,000+ active monitoring stations
|
||||

```
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- **Bun** (JavaScript runtime): https://bun.sh/
|
||||
- **EPA AQS API Key** (free, immediate approval)
|
||||
|
||||
### 1. Register for API Access
|
||||
|
||||
**Option A: Email Registration**
|
||||
```bash
|
||||
# Email aqs.support@epa.gov
|
||||
Subject: AQS API Access Request
|
||||
Body: Please provide API key for email: your_email@example.com
|
||||
```
|
||||
|
||||
**Option B: Automated Signup**
|
||||
```bash
|
||||
curl "https://aqs.epa.gov/data/api/signup?email=your_email@example.com"
|
||||
```
|
||||
|
||||
You will receive your API key via email (typically within minutes).
|
||||
|
||||
### 2. Configure Environment Variables
|
||||
|
||||
```bash
|
||||
# Copy example environment file
|
||||
cp .env.example .env
|
||||
|
||||
# Edit .env with your credentials
|
||||
# Replace your_email@example.com and your_api_key_here
|
||||
nano .env
|
||||
```
|
||||
|
||||
### 3. Fetch Air Quality Data
|
||||
|
||||
**Default: Fetch PM2.5 and Ozone for California (last year)**
|
||||
```bash
|
||||
bun update.ts
|
||||
```
|
||||
|
||||
**Custom: Specify year, states, parameters**
|
||||
```bash
|
||||
# Multiple states, specific year
|
||||
bun update.ts --year 2023 --states CA,NY,TX
|
||||
|
||||
# Focus on PM2.5 only (most health-critical)
|
||||
bun update.ts --year 2023 --states CA --parameters PM25
|
||||
|
||||
# Full criteria pollutants
|
||||
bun update.ts --year 2023 --states CA,NY,TX,FL --parameters PM25,OZONE,SO2,CO,NO2,PM10
|
||||
```
|
||||
|
||||
**Get help**
|
||||
```bash
|
||||
bun update.ts --help
|
||||
```
|
||||
|
||||
### 4. View Results
|
||||
|
||||
Data files are saved in `data/` directory:
|
||||
```bash
|
||||
ls -lh data/
|
||||
# aqs_2023_CA_2025-10-27.json
|
||||
# aqs_2023_CA_stats_2025-10-27.json
|
||||
```
|
||||
|
||||
## API Rate Limits (CRITICAL)
|
||||
|
||||
**EPA enforces strict rate limits:**
|
||||
- ⚠️ **10 requests per minute** (HARD LIMIT)
|
||||
- ⚠️ **Account suspension if violated**
|
||||
|
||||
**The update.ts script automatically enforces 6-second delays between requests.**
|
||||
|
||||
**Do NOT bypass rate limiting.** EPA will suspend your account.
|
||||
|
||||
## Data Validation Lag
|
||||
|
||||
- **Real-time to preliminary:** <1 hour (via AirNow API)
|
||||
- **Preliminary to validated:** 6-12 months (quality assurance)
|
||||
- **AQS finalized data:** 6-12 months after collection
|
||||
|
||||
**For real-time air quality, use AirNow API instead:** https://www.airnow.gov/
|
||||
|
||||
## Environmental Health Context
|
||||
|
||||
### Why Air Quality is a Structural Wellbeing Determinant
|
||||
|
||||
1. **Involuntary Exposure**
|
||||
- You breathe ~20,000 times per day
|
||||
- Cannot avoid ambient air pollution without relocating
|
||||
- Relocation requires economic resources (not "personal choice")
|
||||
|
||||
2. **Life Expectancy Impact**
|
||||
- PM2.5 reduces longevity by months to years in polluted areas
|
||||
- Equivalent to smoking in highly polluted regions
|
||||
- Measurable, quantifiable health burden
|
||||
|
||||
3. **Environmental Injustice**
|
||||
- Low-income communities disproportionately exposed (NEJM 2021)
|
||||
- Communities of color exposed to higher pollution even controlling for income
|
||||
- Proximity to highways, industrial facilities, ports (structural inequality)
|
||||
- **Monitoring gap:** Low-income communities historically undermonitored (data invisibility → policy neglect)
|
||||
|
||||
4. **Health Equity**
|
||||
- Cardiovascular disease: PM2.5 linked to stroke, heart attack, atherosclerosis
|
||||
- Respiratory disease: Asthma, COPD, lung cancer (IARC Group 1 carcinogen)
|
||||
- Cognitive decline: Dementia, Alzheimer's, childhood cognitive impairment
|
||||
- Pregnancy outcomes: Low birth weight, preterm birth
|
||||
|
||||
5. **Quality of Life**
|
||||
- Outdoor activity restrictions on high pollution days
|
||||
- Healthcare costs (emergency visits, hospitalizations)
|
||||
- Lost work/school days (respiratory illness)
|
||||
- Mental health impacts (environmental degradation stress)
|
||||
|
||||
**You cannot "self-care" your way out of this. It requires collective action, policy change, and structural intervention.**
|
||||
|
||||
## Use Cases
|
||||
|
||||
### 1. Environmental Justice Research
|
||||
**Research Question:** Which communities are disproportionately exposed to PM2.5?
|
||||
|
||||
```bash
|
||||
# Fetch PM2.5 data for multiple states
|
||||
bun update.ts --year 2023 --states CA,NY,TX,IL --parameters PM25
|
||||
|
||||
# Cross-reference with Census demographic data (DS-00006)
|
||||
# Identify exposure disparities by race, income, ZIP code
|
||||
```
|
||||
|
||||
### 2. Life Expectancy Modeling
|
||||
**Research Question:** How does PM2.5 exposure impact life expectancy across U.S. counties?
|
||||
|
||||
```bash
|
||||
# Fetch multi-year PM2.5 data
|
||||
bun update.ts --year 2023 --states ALL --parameters PM25
|
||||
|
||||
# Link to CDC mortality data (DS-00005)
|
||||
# Calculate life expectancy impact using AQLI conversion factors
|
||||
# (1 µg/m³ PM2.5 increase = ~0.1 year life expectancy loss)
|
||||
```
|
||||
|
||||
### 3. Policy Evaluation
|
||||
**Research Question:** Did Clean Air Act regulations reduce ozone levels?
|
||||
|
||||
```bash
|
||||
# Fetch historical data (multiple years)
|
||||
bun update.ts --year 2020 --states CA --parameters OZONE
|
||||
bun update.ts --year 2015 --states CA --parameters OZONE
|
||||
bun update.ts --year 2010 --states CA --parameters OZONE
|
||||
|
||||
# Analyze trends over time
|
||||
# Evaluate regulatory effectiveness
|
||||
```
|
||||
|
||||
### 4. Health Impact Assessment
|
||||
**Research Question:** What are the health costs of air pollution in California?
|
||||
|
||||
```bash
|
||||
# Fetch PM2.5 and Ozone
|
||||
bun update.ts --year 2023 --states CA --parameters PM25,OZONE
|
||||
|
||||
# Link to health outcomes data (hospitalizations, mortality)
|
||||
# Calculate attributable burden using EPA BenMAP tools
|
||||
```
|
||||
|
||||
## Known Limitations
|
||||
|
||||
### Coverage Gaps
|
||||
- **Urban bias:** 85% of monitors in metropolitan areas; rural areas undermonitored
|
||||
- **Environmental justice monitoring gap:** Low-income communities historically excluded
|
||||
- **Tribal lands:** Limited tribal monitoring (improving)
|
||||
- **Territories:** Limited coverage in Puerto Rico, U.S. Virgin Islands
|
||||
|
||||
### Methodological Limitations
|
||||
- **Point measurements:** Monitors represent ~1-10 km radius (not every location monitored)
|
||||
- **24-hour averages for PM:** Daily averages mask hour-to-hour variability
|
||||
- **Spatial scale mismatch:** Within-neighborhood gradients missed
|
||||
- **Indoor air quality:** Not measured (people spend 90% of time indoors)
|
||||
|
||||
### Temporal Limitations
|
||||
- **6-12 month validation lag:** Not suitable for real-time analysis (use AirNow API)
|
||||
- **Historical data:** Digital records begin 1980 (pre-1980 limited)
|
||||
|
||||
### Inappropriate Uses
|
||||
1. ❌ **DO NOT use for real-time alerts** → Use AirNow API
|
||||
2. ❌ **DO NOT use for individual exposure** → Use personal monitors, exposure modeling
|
||||
3. ❌ **DO NOT assume unmonitored = clean** → Absence of data ≠ absence of pollution
|
||||
4. ❌ **DO NOT ignore monitoring gaps** → Undermonitoring = data invisibility

## Parameter Codes
|
||||
|
||||
| Code | Parameter | Health Impact |
|
||||
|------|-----------|---------------|
|
||||
| 88101 | PM2.5 | **MOST CRITICAL** — Fine particulate matter linked to mortality, cardiovascular disease, respiratory disease, cognitive decline |
|
||||
| 44201 | Ozone (O3) | Respiratory irritant, smog precursor, asthma exacerbation |
|
||||
| 42401 | Sulfur Dioxide (SO2) | Respiratory irritant |
|
||||
| 42101 | Carbon Monoxide (CO) | Cardiovascular stress |
|
||||
| 42602 | Nitrogen Dioxide (NO2) | Respiratory irritant, precursor to ozone/PM |
|
||||
| 81102 | PM10 | Coarse particulate matter, respiratory health |
|
||||
|
||||
## Air Quality Index (AQI) Interpretation
|
||||
|
||||
| AQI Range | Category | Health Implications |
|
||||
|-----------|----------|---------------------|
|
||||
| 0-50 | Good | Air quality satisfactory, little or no health risk |
|
||||
| 51-100 | Moderate | Acceptable; unusually sensitive people may experience respiratory symptoms |
|
||||
| 101-150 | Unhealthy for Sensitive Groups | Sensitive groups (children, elderly, respiratory/cardiovascular conditions) may experience health effects |
|
||||
| 151-200 | Unhealthy | Everyone may begin to experience health effects; sensitive groups more serious effects |
|
||||
| 201-300 | Very Unhealthy | Health alert — everyone may experience serious health effects |
|
||||
| 301+ | Hazardous | Health warning — emergency conditions; entire population likely affected |
|
||||
|
||||
## Environmental Health Context
|
||||
|
||||
**Air quality is a structural determinant of wellbeing.**
|
||||
|
||||
- **PM2.5 reduces life expectancy** by months to years in polluted areas (Air Quality Life Index estimates 1.8 years lost globally)
|
||||
- **Environmental injustice:** Low-income communities and communities of color disproportionately exposed to air pollution
|
||||
- **Involuntary exposure:** You breathe ~20,000 times per day — cannot "self-care" your way out of toxic air
|
||||
- **ZIP code determines exposure:** Structural constraint on wellbeing (requires resources to relocate)
|
||||
|
||||
## Data Quality Notes
|
||||
|
||||
- **Validation lag:** 6-12 months from collection to finalized data in AQS
|
||||
- **Spatial coverage:** Urban bias — rural areas undermonitored
|
||||
- **Environmental justice monitoring gap:** Low-income communities historically undermonitored
|
||||
- **FRM/FEM methods:** Federal Reference/Equivalent Methods — regulatory-grade quality
|
||||
- **Missing data:** Instrument downtime, maintenance typically results in <10% missing data per site-year
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Calculate annual average PM2.5 by county
|
||||
```typescript
|
||||
const data = await Bun.file('aqs_2023_CA_2025-10-27.json').json();
|
||||
const pm25Data = data.dailyData.filter(d => d.parameter_code === '88101');
|
||||
|
||||
const byCounty = new Map();
|
||||
for (const record of pm25Data) {
|
||||
const key = `${record.state}_${record.county}`;
|
||||
if (!byCounty.has(key)) {
|
||||
byCounty.set(key, []);
|
||||
}
|
||||
byCounty.get(key).push(record.arithmetic_mean);
|
||||
}
|
||||
|
||||
for (const [county, values] of byCounty.entries()) {
|
||||
const avg = values.reduce((a, b) => a + b, 0) / values.length;
|
||||
console.log(`${county}: ${avg.toFixed(2)} µg/m³`);
|
||||
}
|
||||
```
|
||||
|
||||
### Identify environmental justice hotspots (high PM2.5 areas)
|
||||
```typescript
|
||||
const highPM25Sites = pm25Data
|
||||
.filter(d => d.arithmetic_mean > 12.0) // EPA annual standard: 12.0 µg/m³
|
||||
.map(d => ({
|
||||
site: d.local_site_name,
|
||||
city: d.city,
|
||||
county: d.county,
|
||||
latitude: d.latitude,
|
||||
longitude: d.longitude,
|
||||
pm25: d.arithmetic_mean,
|
||||
}));
|
||||
|
||||
// Cross-reference with Census demographic data for environmental justice analysis
|
||||
```

### Relevance Assessment
|
||||
|
||||
**Substrate Mission Alignment:**
|
||||
- **Human Progress Focus:** **CRITICAL** — Air quality is structural determinant of human wellbeing; you cannot "self-care" your way out of breathing toxic air
|
||||
- **Problem-Solution Connection:**
|
||||
- **Links to Problems:** Respiratory disease, cardiovascular disease, cognitive decline, reduced life expectancy, environmental injustice, health inequity
|
||||
- **Links to Solutions:** Clean Air Act regulations, emissions reductions, environmental justice policy, urban planning, transportation electrification
|
||||
- **Evidence Quality:** Gold-standard measurements; legally defensible; peer-reviewed methods; 50+ years of methodological refinement
|
||||
|
||||
**Why Air Quality Matters for Wellbeing (CRITICAL FRAMING):**
|
||||
|
||||
**Air Quality as Structural Wellbeing Determinant:**
|
||||
- **PM2.5 reduces life expectancy** by months to years in polluted areas (AQLI estimates 1.8 years lost globally)
|
||||
- **You cannot choose cleaner air** without economic resources to relocate (ZIP code determines exposure)
|
||||
- **Environmental injustice:** Low-income communities, communities of color disproportionately exposed to air pollution (NEJM 2021 study: exposure disparities persist even controlling for income)
|
||||
- **Invisible, involuntary harm:** You breathe ~20,000 times per day — air quality affects every breath
|
||||
- **Measurable, preventable:** Unlike many health risks, air pollution is quantifiable, monitored, and addressable through policy
|
||||
|
||||
**Health Impacts (Evidence-Based):**
|
||||
- **Mortality:** PM2.5 linked to all-cause mortality, cardiovascular mortality, respiratory mortality (Harvard Six Cities Study, ACS CPS-II)
|
||||
- **Cardiovascular Disease:** Stroke, heart attack, atherosclerosis (AHA Scientific Statement 2010)
|
||||
- **Respiratory Disease:** Asthma exacerbation, COPD, lung cancer (IARC Group 1 carcinogen)
|
||||
- **Cognitive Decline:** Dementia, Alzheimer's, cognitive impairment in children (USC/KECK studies)
|
||||
- **Pregnancy Outcomes:** Low birth weight, preterm birth (meta-analyses)
|
||||
- **Life Expectancy:** Equivalent impact to smoking in highly polluted areas
|
||||
|
||||
**Economic and Quality of Life:**
|
||||
- **Lost work/school days:** Respiratory illness costs billions in productivity
|
||||
- **Healthcare costs:** Emergency visits, hospitalizations, medications
|
||||
- **Restricted activity:** Cannot exercise outdoors on high pollution days
|
||||
- **Mental health:** Psychological stress from environmental degradation
|
||||
|
||||
**Collection Priorities Match:**
|
||||
- **Priority Level:** **CRITICAL** — Essential source for environmental health and wellbeing domain
|
||||
- **Uniqueness:** Only authoritative, regulatory-grade, long-term ambient air quality dataset for United States
|
||||
- **Comprehensiveness:** Fills critical gap — no other source provides combination of legal authority, data quality, temporal depth, spatial coverage
|
||||
|
||||

## Source Evaluation Narrative
|
||||
|
||||
### Methodological Assessment
|
||||
|
||||
**Data Collection Methodology:**
|
||||
|
||||
**Monitoring Station Design:**
|
||||
- **Method:** Continuous automated monitoring using Federal Reference Methods (FRM) or Federal Equivalent Methods (FEM)
|
||||
- **Site Selection:** 40 CFR Part 58 Appendix D specifies site selection criteria (population-based, source-oriented, background sites)
|
||||
- **Spatial Coverage:** 4,000+ active monitors; denser in urban areas; required monitors for NAAQS pollutants in metropolitan areas
|
||||
- **Stratification:** Urban/suburban/rural; near-road/neighborhood/regional scales
|
||||
- **Site Types:** SLAMS (State/Local Air Monitoring Stations), NAMS (National Air Monitoring Stations), PAMS (Photochemical Assessment Monitoring Stations), tribal monitors
|
||||
|
||||
**Measurement Instruments:**
|
||||
- **Instrument Type:** FRM/FEM analyzers (e.g., Beta Attenuation Monitors for PM2.5, UV photometry for O3, chemiluminescence for NO2)
|
||||
- **Validation:** All methods must demonstrate equivalence to FRM through EPA approval process
|
||||
- **Calibration:** Regular calibration per 40 CFR Part 58 (daily zero/span checks, quarterly audits)
|
||||
- **Mode:** Continuous automated measurement with data loggers; telemetry transmission to AQS
|
||||
|
||||
**Quality Control Procedures:**
|
||||
- **Field QA:** Quarterly audits, collocated samplers (precision checks), flow rate audits, temperature/pressure checks
|
||||
- **Validation Rules:** Automated flagging of invalid data (instrument malfunction, calibration failure, suspect data)
|
||||
- **Consistency Checks:** Cross-parameter validation (meteorologically implausible conditions flagged)
|
||||
- **Verification:** EPA regional offices review state/local data; annual data certification process
|
||||
- **Outlier Treatment:** Flagged for review; extreme values verified or invalidated; natural events (wildfires, dust storms) documented
|
||||
|
||||
**Error Characteristics:**
|
||||
- **Sampling Error:** Minimal (continuous monitoring, not statistical sampling)
|
||||
- **Non-sampling Error:**
|
||||
- Instrument error: ±10-15% for PM2.5 (BAM vs. gravimetric FRM); ±5% for O3
|
||||
- Spatial representativeness: Monitor represents ~1-10 km radius depending on scale
|
||||
- Temporal gaps: Instrument downtime (maintenance, malfunctions)
|
||||
- **Known Biases:**
|
||||
- Urban bias in monitoring network (rural areas undermonitored)
|
||||
- Environmental justice monitoring gap (low-income communities historically undermonitored)
|
||||
- Near-road monitors added only in 2010s (underestimated traffic impacts historically)
|
||||
- **Accuracy Bounds:** FRM/FEM methods must demonstrate ±10% accuracy vs. reference methods; regulatory decisions use three-year averages to reduce uncertainty
|
||||
|
||||
**Methodology Documentation:**
|
||||
- **Transparency Level:** 5/5 (Exhaustive)
|
||||
- **Documentation URL:** 40 CFR Part 58 (federal regulations): https://www.ecfr.gov/current/title-40/chapter-I/subchapter-C/part-58
|
||||
- **Peer Review Status:** Methods peer-reviewed through Federal Register notice-and-comment; Scientific Advisory Board oversight
|
||||
- **Reproducibility:** Fully reproducible — FRM/FEM methods published; raw data available; QA procedures documented
|
||||
|
||||
### Currency Assessment
|
||||
|
||||
**Update Characteristics:**
|
||||
- **Update Frequency:** Continuous (monitors transmit hourly); daily uploads to AQS; quarterly data validation cycles
|
||||
- **Update Reliability:** Highly reliable (automated telemetry); 6-month lag for finalized validated data
|
||||
- **Update Notification:** No API notifications; annual data certification announcements
|
||||
- **Last Updated:** Data current through 6 months ago (validated); preliminary data more current via AirNow
|
||||
|
||||
**Timeliness:**
|
||||
- **Collection to Publication Lag:**
|
||||
- Real-time to preliminary: <1 hour (via AirNow API)
|
||||
- Preliminary to validated: 6-12 months (quality assurance process)
|
||||
- Finalized data in AQS: 6-12 months after collection
|
||||
- **Factors Affecting Timeliness:** State/local agency validation cycles; EPA review cycles; data corrections/resubmissions
|
||||
- **Historical Timeliness:** Consistent 6-month lag; accelerated during COVID-19 for health surveillance
|
||||
|
||||
**Currency for Different Uses:**
|
||||
- **Real-time Analysis:** Unsuitable for AQS (use AirNow API instead)
|
||||
- **Recent Trends:** Suitable for annual/multi-year trends; unsuitable for month-to-month changes (validation lag)
|
||||
- **Historical Research:** Excellent — 45-year validated time series
|
||||
|
||||
### Objectivity Assessment
|
||||
|
||||
**Potential Biases:**
|
||||
|
||||
**Political Bias:**
|
||||
- **Government Influence:** EPA subject to political pressure (NAAQS standards controversial; industry lobbying); however, Clean Air Act statutory requirements limit discretion
|
||||
- **Editorial Stance:** Scientific integrity policy protects staff; data publication non-discretionary (all validated data published)
|
||||
- **Political Pressure:** Historical examples of political interference (Trump administration NAAQS delays); career staff maintain scientific standards; data integrity high despite political pressures
|
||||
|
||||
**Commercial Bias:**
|
||||
- **Funding Sources:** Federal appropriations only; no commercial funding
|
||||
- **Industry Influence:** Industry lobbying affects NAAQS stringency (standard-setting); does not affect monitoring data collection/publication
|
||||
- **Proprietary Interests:** None
|
||||
|
||||
**Cultural/Social Bias:**
|
||||
- **Geographic Bias:** **CRITICAL ENVIRONMENTAL JUSTICE ISSUE** — Urban bias in monitoring network; rural and low-income communities undermonitored; tribal lands historically excluded (improving)
|
||||
- **Social Perspective:** Regulatory perspective (NAAQS compliance focus); less emphasis on cumulative exposures, indoor air quality, occupational exposures
|
||||
- **Language Bias:** English only (no Spanish/multilingual data portal)
|
||||
- **Selection Bias:** Monitoring site placement historically prioritized compliance monitoring (regulatory focus) over health equity (exposure disparities)
|
||||
|
||||
**Transparency:**
|
||||
- **Bias Disclosure:** EPA acknowledges monitoring gaps in environmental justice communities; recent initiatives to expand monitoring in underserved areas
|
||||
- **Limitations Stated:** QA flags documented; measurement uncertainty noted; network limitations acknowledged
|
||||
- **Raw Data Available:** Yes — all validated data public; preliminary data via AirNow; QA data available
|
||||
|
||||
### Reliability Assessment
|
||||
|
||||
**Consistency:**
|
||||
- **Internal Consistency:** Excellent — QA procedures ensure data coherence; collocated monitors show high agreement (r>0.9 for PM2.5)
|
||||
- **Temporal Consistency:** Very good — methods stable over time; method changes documented (e.g., transition from dichot samplers to continuous monitors)
|
||||
- **Cross-source Consistency:** Good agreement with satellite data (MODIS AOD), low-cost sensors (after calibration), research-grade monitors
|
||||
|
||||
**Stability:**
|
||||
- **Definition Changes:** Rare — NAAQS revisions change regulatory standards (not measurement definitions); PM2.5 definition stable since 1997
|
||||
- **Methodology Changes:** Infrequent — new FEM methods added periodically; FRM remains stable reference
|
||||
- **Series Breaks:** Minimal — method transitions documented; historical data not revised (preserves time series integrity)
|
||||
|
||||
**Verification:**
|
||||
- **Independent Verification:** Collocated monitors (precision audits); EPA audits (Performance Evaluation Programs); academic validation studies
|
||||
- **Replication Studies:** Thousands of health studies use AQS data; measurement errors identified and corrected through peer review
|
||||
- **Audit Results:** Quarterly audits required by 40 CFR Part 58; results public; high pass rates (>90%)
|
||||
|
||||
### Accuracy Assessment
|
||||
|
||||
**Validation Evidence:**
|
||||
- **Benchmark Comparisons:** FRM/FEM methods validated against laboratory standards; field comparisons show ±10% agreement
|
||||
- **Coverage Assessments:** Network adequacy reviewed in 5-year monitoring network assessments
|
||||
- **Error Studies:** Measurement uncertainty quantified in method validation studies; typical uncertainty ±10-15% for PM2.5, ±5% for O3
|
||||
|
||||
**Accuracy for Different Uses:**
|
||||
- **Point Estimates:** High accuracy for individual measurements (±10-15% typical)
|
||||
- **Trend Analysis:** Very high reliability for multi-year trends (measurement error random, cancels over time)
|
||||
- **Cross-sectional Comparison:** Reliable for comparing locations (standardized methods)
|
||||
- **Sub-population Analysis:** **LIMITED** — Monitors represent area averages (~1-10 km); cannot assess within-neighborhood gradients or individual exposures (requires modeling)
|
||||

## Known Limitations and Caveats
|
||||
|
||||
### Coverage Limitations
|
||||
|
||||
**Geographic Gaps:**
|
||||
- **Rural areas severely undermonitored:** 85% of monitors in metropolitan areas; vast rural regions with no coverage
|
||||
- **Environmental justice monitoring gap:** Low-income communities, communities of color historically undermonitored; fence-line communities near industrial sources lacking monitors
|
||||
- **Tribal lands:** Limited tribal monitoring (improving under recent EPA grants)
|
||||
- **Territories:** Limited coverage in Puerto Rico, U.S. Virgin Islands (worse after hurricanes)
|
||||
- **Mobile sources:** Near-road monitors added only in 2010s; traffic exposure historically underestimated
|
||||
|
||||
**Temporal Gaps:**
|
||||
- **Historical data:** Digital records begin 1980; pre-1980 data limited
|
||||
- **Instrument downtime:** Maintenance, malfunctions cause data gaps (typically <10% missing data per site-year)
|
||||
- **Discontinued sites:** Some long-term sites closed due to budget cuts (loss of historical continuity)
|
||||
|
||||
**Population Exclusions:**
|
||||
- **Indoor air quality:** Not measured (people spend 90% of time indoors)
|
||||
- **Occupational exposures:** Not captured (workplace exposures separate)
|
||||
- **Personal exposures:** Monitor represents area average, not individual exposure (commuting, activity patterns affect personal exposure)
|
||||
|
||||
**Variable Gaps:**
|
||||
- **Ultrafine particles (<0.1 μm):** Not routinely monitored (health concerns emerging)
|
||||
- **Chemical speciation:** Limited speciated PM2.5 (metals, organics, ions) compared to total mass
|
||||
- **Biological aerosols:** Pollen, mold spores not systematically monitored
|
||||
- **Emerging pollutants:** PFAS, microplastics in air not monitored
|
||||
|
||||
### Methodological Limitations
|
||||
|
||||
**Spatial Limitations:**
|
||||
- **Point measurements:** Monitors measure concentration at one location; spatial interpolation required to estimate exposures elsewhere (introduces uncertainty)
|
||||
- **Spatial scale mismatch:** Monitor represents ~1-10 km radius; exposure disparities within neighborhoods missed
|
||||
- **Topographic effects:** Complex terrain (mountains, valleys) creates microclimates; single monitor may not represent entire area
|
||||
|
||||
**Temporal Limitations:**
|
||||
- **24-hour averages for PM:** Daily averages mask hour-to-hour variability (peak exposures missed)
|
||||
- **Sampling frequency:** PM2.5 measured every 1-6 days at many sites (not continuous); introduces temporal aliasing
|
||||
- **Long-term averages:** NAAQS compliance uses 3-year averages (smooths variability; short-term spikes averaged out)
|
||||
|
||||
**Measurement Limitations:**
|
||||
- **Semi-volatile compounds:** PM2.5 measurement affected by temperature (semi-volatile organics evaporate from filters)
|
||||
- **Instrument artifacts:** Positive artifacts (adsorption of gases onto filters), negative artifacts (evaporation of volatile PM)
|
||||
- **Humidity effects:** Hygroscopic growth (particles absorb water; mass increases in humid conditions)
|
||||
|
||||
### Comparability Limitations
|
||||
|
||||
**Cross-site Comparability:**
|
||||
- **Method differences:** FRM vs. FEM methods not perfectly equivalent (±10% differences possible)
|
||||
- **Site characteristics:** Urban vs. rural, near-road vs. neighborhood, upwind vs. downwind (not directly comparable without context)
|
||||
- **Operational differences:** State/local agencies vary in QA rigor (federal requirements ensure minimum standards but practices vary)
|
||||
|
||||
**Temporal Comparability:**
|
||||
- **Method changes:** Transition from manual to automated methods (1990s-2000s); FRM to FEM (2000s-present)
|
||||
- **Network changes:** Site additions/closures; near-road monitors added 2010s (changes network composition)
|
||||
- **NAAQS revisions:** Regulatory standards change (PM2.5 standard added 1997, revised 2006, 2012, 2024); historical data comparable but compliance status not
|
||||
|
||||
**Parameter Comparability:**
|
||||
- **Different averaging times:** PM2.5 (24-hr), O3 (8-hr), NO2 (1-hr, annual) — cannot directly compare across pollutants without standardization
|
||||
- **Different health effects:** PM2.5 (chronic exposure) vs. O3 (acute exposure) — different exposure metrics relevant
|
||||
|
||||
### Usage Caveats
|
||||
|
||||
**Inappropriate Uses:**
|
||||
1. **DO NOT use for real-time air quality alerts** — use AirNow API instead (AQS has 6-month validation lag)
|
||||
2. **DO NOT use for individual exposure assessment** — monitors represent area averages, not personal exposure (requires exposure modeling)
|
||||
3. **DO NOT assume unmonitored areas are clean** — absence of data ≠ absence of pollution (monitoring gap bias)
|
||||
4. **DO NOT ignore environmental justice monitoring gaps** — undermonitoring in low-income communities creates data deserts (policy invisibility)
|
||||
5. **DO NOT use for source attribution** — AQS measures ambient concentrations, not sources (requires source apportionment modeling)
|
||||
|
||||
**Ecological Fallacy Risks:**
|
||||
- Area-level pollution does not equal individual exposure (activity patterns, microenvironments matter)
|
||||
- County-level averages mask within-county disparities (ZIP code, neighborhood-level variation lost)
|
||||
|
||||
**Correlation vs. Causation:**
|
||||
- AQS data appropriate for exposure assessment in epidemiological studies (with proper exposure modeling)
|
||||
- Health effects studies require individual-level health data linked to exposure estimates (not possible with AQS alone)
|
||||
- Natural experiments (policy changes, wildfires) useful for causal inference but require careful study design
|
||||
|
||||
**Environmental Justice Caveats:**
|
||||
- **Monitoring gap = data invisibility:** Low-income communities, communities of color undermonitored → exposures underestimated → policy neglect reinforced
|
||||
- **Regulatory compliance ≠ health equity:** Meeting NAAQS does not eliminate disparities (some communities exposed to higher pollution even when region meets standards)
|
||||
- **Cumulative impacts missed:** AQS measures one pollutant at a time; cumulative burden of multiple pollutants, non-air stressors not captured

## Recommended Use Cases
|
||||
|
||||
### Ideal Applications
|
||||
|
||||
**Research Questions Well-Suited:**
|
||||
1. "How has U.S. air quality changed since the Clean Air Act? (Policy evaluation)"
|
||||
2. "Which communities are disproportionately exposed to PM2.5? (Environmental justice)"
|
||||
3. "What is the relationship between PM2.5 and life expectancy across U.S. counties? (Health equity)"
|
||||
4. "Do air quality trends differ between urban and rural areas? (Geographic disparities)"
|
||||
5. "How do wildfire smoke events affect air quality in Western states? (Natural disasters)"
|
||||
|
||||
**Analysis Types Supported:**
|
||||
- **Time series analysis:** Long-term trends (1980-present)
|
||||
- **Geographic analysis:** Spatial patterns, exposure disparities, environmental justice hotspots
|
||||
- **Policy evaluation:** Before/after regulatory changes (Clean Air Act amendments, state policies)
|
||||
- **Exposure assessment:** Epidemiological studies linking air quality to health outcomes
|
||||
- **Extreme event analysis:** Wildfires, dust storms, pollution episodes
|
||||
|
||||
### Appropriate Contexts
|
||||
|
||||
**Geographic Contexts:**
|
||||
- **U.S. national trends** (aggregated data)
|
||||
- **State/regional comparisons** (regulatory jurisdiction)
|
||||
- **County-level analysis** (health departments, epidemiology)
|
||||
- **Monitoring site-level** (exposure assessment, environmental justice)
|
||||
- **Urban vs. rural disparities** (structural determinants)
|
||||
|
||||
**Temporal Contexts:**
|
||||
- **Long-term trends** (decades; policy evaluation)
|
||||
- **Seasonal patterns** (O3 in summer, PM2.5 in winter)
|
||||
- **Annual averages** (NAAQS compliance, health studies)
|
||||
- **Historical research** (Clean Air Act effectiveness)
|
||||
|
||||
**Subject Contexts:**
|
||||
- **Environmental health** (PM2.5, O3 health effects)
|
||||
- **Structural wellbeing determinants** (ZIP code determines exposure)
|
||||
- **Environmental justice** (exposure disparities by race, income)
|
||||
- **Quality of life** (outdoor activity restrictions on high pollution days)
|
||||
- **Life expectancy modeling** (PM2.5 as longevity determinant)
|
||||
|
||||
### Use Warnings
|
||||
|
||||
**Avoid Using This Source For:**
|
||||
1. **Individual exposure assessment** → Use personal monitors, exposure modeling, or indoor air quality data
|
||||
2. **Real-time air quality** → Use AirNow API (current conditions)
|
||||
3. **Global comparisons** → Use WHO Global Air Quality Database, satellite data (AQS is U.S. only)
|
||||
4. **Source attribution** → Use EPA National Emissions Inventory, source apportionment modeling
|
||||
5. **Indoor air quality** → Use indoor monitoring studies, building sensors
|
||||
|
||||
**Recommended Alternatives For:**
|
||||
- **Real-time data** → AirNow API (https://www.airnow.gov/), PurpleAir (low-cost sensors)
|
||||
- **Global coverage** → WHO Global Air Quality Database, OpenAQ, satellite data (NASA MODIS, Sentinel)
|
||||
- **Higher spatial resolution** → Low-cost sensor networks (PurpleAir), land-use regression models, satellite data
|
||||
- **Individual exposure** → Personal monitors (wearable sensors), GPS-based exposure modeling
|
||||
- **Indoor air quality** → Indoor air quality monitors, EPA Indoor Air Quality Program

## Cataloger Notes
|
||||
|
||||
**Internal Notes:**
|
||||
- **CRITICAL SOURCE** for environmental health and structural wellbeing determinants
|
||||
- Excellent data quality; regulatory-grade measurements; long time series
|
||||
- **Environmental justice emphasis:** Monitoring gap in low-income communities = data invisibility = policy neglect
|
||||
- **Unique framing:** Air quality as structural constraint on wellbeing (cannot self-care out of toxic air)
|
||||
- API stable but slow (10 req/min rate limit); recommend 6-second delays between requests
|
||||
- Consider integrating with Census ACS demographic data for environmental justice analysis
|
||||
|
||||
**To Do:**
|
||||
- [ ] Create update.ts script with rate limiting (6-second delays)
|
||||
- [ ] Test API with sample requests (PM2.5, Ozone)
|
||||
- [ ] Cross-reference with CDC WONDER mortality data
|
||||
- [ ] Link to environmental justice problems/solutions
|
||||
- [ ] Consider creating derived dataset: "Life Expectancy Impact by County" (PM2.5 × AQLI conversion factors)
|
||||
|
||||
**Questions for Review:**
|
||||
- Should we prioritize PM2.5 and Ozone exclusively (most health-relevant) or include all criteria pollutants?
|
||||
- How to handle environmental justice monitoring gaps in documentation (acknowledge limitation prominently)?
|
||||
- Should we create companion dataset for AirNow API (real-time) vs. AQS (historical)?

# Wellbeing Data Sources - Implementation Guide
|
||||
|
||||
**Created:** 2025-10-27
|
||||
**Purpose:** Document the five new wellbeing data sources added to Substrate to measure actual state of people
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
This document describes five critical data sources added to Substrate on 2025-10-27 to track human wellbeing beyond traditional economic indicators. These sources were selected based on:
|
||||
|
||||
1. **Free access** with excellent APIs
|
||||
2. **High quality** and authoritative
|
||||
3. **Leading indicators** that reveal wellbeing before traditional metrics
|
||||
4. **Behavioral truth** - actions reveal reality surveys miss
|
||||
5. **Coverage of critical dimensions** - economic, health, social, environmental
|
||||
|
||||

|
||||
|
||||
## The Five New Data Sources
|
||||
|
||||
### DS-00004 — FRED Economic Wellbeing
|
||||
|
||||
**Organization:** Federal Reserve Bank of St. Louis
|
||||
**API:** https://api.stlouisfed.org/fred/
|
||||
**Update Frequency:** Weekly to Annual (varies by indicator)
|
||||
**Geographic Coverage:** US National
|
||||
|
||||
**Critical Indicators:**
|
||||
- **TDSP** - Household Debt Service Ratio (quarterly) - Aggregate financial stress
|
||||
- **DRCCLACBS** - Credit Card Delinquency Rate (quarterly) - Consumer distress signal
|
||||
- **STLFSI4** - Financial Stress Index (weekly!) - Real-time system stress
|
||||
- **LNS13327709** - U-6 Underemployment Rate (monthly) - True labor slack
|
||||
- **UEMP27OV** - Long-term Unemployed 27+ weeks (monthly) - Structural problems
|
||||
- **UMCSENT** - Consumer Sentiment (monthly) - Economic confidence
|
||||
- **SIPOVGINIUSA** - GINI Index (annual) - Income inequality
|
||||
- **MORTGAGE30US** - 30-Year Mortgage Rate (weekly) - Housing affordability
|
||||
- **MSPUS** - Median Home Sales Price (quarterly) - Home price affordability
|
||||
- **PSAVERT** - Personal Saving Rate (monthly) - Financial resilience
|
||||
|
||||
**Why It Matters:**

### DS-00005 — CDC WONDER Mortality Database
|
||||
|
||||
**Organization:** Centers for Disease Control and Prevention (CDC)
|
||||
**API:** https://wonder.cdc.gov/controller/datarequest/ (XML)
|
||||
**Update Frequency:** Annual (with 1-2 year lag)
|
||||
**Geographic Coverage:** US National, State, County
|
||||
|
||||
**Critical Indicators:**
|
||||
- **Drug Overdose Deaths** (ICD-10: X40-X44, X60-X64, X85, Y10-Y14)
|
||||
- **Opioid-Specific Deaths** (T40.0-T40.4, T40.6)
|
||||
- **Suicide Deaths** (X60-X84, Y87.0, U03)
|
||||
- **All-Cause Mortality Rates**
|
||||
|
||||
**Why It Matters:**
|
||||
- **Leading indicators** - Overdoses and suicides precede economic decline
|
||||
- **Behavioral truth** - Deaths reveal desperation surveys miss
|
||||
- **County-level granularity** - Shows which communities are suffering
|
||||
- **"Deaths of despair"** - Captures breakdown in social fabric and hope
|
||||
- Only official source for county-level crisis mortality
|
||||
|
||||
**Unique Insight:**
|
||||
- These are not random health events - they're signals of community breakdown
|
||||
- Geographic patterns show "left behind" populations
|
||||
- Crisis indicators that traditional wellbeing metrics miss entirely
|
||||
|
||||
**Setup:**
|
||||

### DS-00006 — Census ACS Social Wellbeing
|
||||
|
||||
**Organization:** US Census Bureau
|
||||
**API:** https://api.census.gov/data/{year}/acs/acs1
|
||||
**Update Frequency:** Annual (1-year and 5-year estimates)
|
||||
**Geographic Coverage:** National, State, County, City, Census Tract
|
||||
|
||||
**Critical Indicators:**
|
||||
- **B11001_008E** - 1-Person Households (living alone) - Social isolation
|
||||
- **B08303_001E** - Mean Travel Time to Work - Time poverty
|
||||
- **B08303_013E** - Commute 60+ minutes - Extreme time poverty
|
||||
- **B28002_013E** - No Internet Access at Home - Digital divide
|
||||
- **B19013_001E** - Median Household Income - Economic security
|
||||
- **B25064_001E** - Median Gross Rent - Housing affordability
|
||||
- **B23025_005E** - Unemployed Population - Labor market health
|
||||
|
||||
**Why It Matters:**
|
||||
- **Social connection** - Living alone rates reveal structural isolation
|
||||
- **Time poverty** - Long commutes reduce social connection, increase stress
|
||||
- **Digital divide** - Internet access = opportunity access in modern economy
|
||||
- **Most granular source** - Down to census tract level (neighborhood data)
|
||||
- **Denominators** - Population data needed to calculate rates
|
||||
|
||||
**Unique Insight:**
|
||||
- You can be economically comfortable but socially isolated (suburban paradox)
|
||||
- Time poverty (commute) often invisible in income statistics
|
||||
- Structural determinants you can't "self-care" your way out of
|
||||
|

### DS-00007 — BLS JOLTS Labor Market
|
||||
|
||||
**Organization:** Bureau of Labor Statistics (BLS)
|
||||
**API:** https://api.bls.gov/publicAPI/v2/timeseries/data/
|
||||
**Update Frequency:** Monthly (with ~6 week lag)
|
||||
**Geographic Coverage:** US National, some State
|
||||
|
||||
**Critical Indicators (via FRED for reliability):**
|
||||
- **JTSQUR** - Quit Rate (Total Nonfarm) - **MOST IMPORTANT**
|
||||
- **JTSJOR** - Job Openings Rate - Opportunity availability
|
||||
- **JTSHIR** - Hire Rate - Labor market dynamism
|
||||
- **JTSLD** - Layoff and Discharge Rate - Involuntary separations
|
||||
- **JTSTSR** - Total Separations Rate - Overall turnover
|
||||
|
||||
**Why It Matters - The "Permission to Quit Index":**
|
||||
- **People only quit when they have options** - Quit rate measures worker agency
|
||||
- High quit rate = Worker empowerment, confidence, economic security
|
||||
- Low quit rate during "good economy" = Trapped workers (hidden desperation)
|
||||
- Leading indicator of wage growth (quits force employers to raise wages)
|
||||
- Reveals worker experience that GDP and unemployment miss
|
||||
|
||||
**Unique Framework:**
|
||||
- "Permission to Quit" measures economic freedom and worker dignity
|
||||
- Distinguishes voluntary (quits) from involuntary (layoffs) separations
|
||||
- Worker-centric view of economy (not just employer/investor perspective)
|
||||
|
||||
**Setup:**
|
||||
```bash
|
||||
# Optional: Get free BLS API key for higher rate limits
|
||||
# https://www.bls.gov/developers/home.htm
|
||||
export BLS_API_KEY="your_key_here" # Optional
|

export FRED_API_KEY="your_key_here" # Required (data via FRED)
|
||||
cd Data-Sources/DS-00007—BLS_JOLTS_Labor_Market
|
||||
./update.ts
|
||||
```
|
||||
|
||||
**Note:** Update script uses FRED API to access JOLTS data (more reliable than direct BLS API). Original BLS series IDs changed format in 2020.
|
||||

|
||||
|
||||
### DS-00008 — EPA Air Quality System
|
||||
|
||||
**Organization:** Environmental Protection Agency (EPA)
|
||||
**API:** https://aqs.epa.gov/data/api/
|
||||
**Update Frequency:** Hourly (real-time) to Annual summaries
|
||||
**Geographic Coverage:** US National, State, County, Monitoring Station
|
||||
|
||||
**Critical Indicators:**
|
||||
- **88101** - PM2.5 (fine particulate matter) - **MOST CRITICAL**
|
||||
- **44201** - Ozone (O3) - Respiratory and cardiovascular impacts
|
||||
- **42401** - Sulfur Dioxide (SO2)
|
||||
- **42101** - Carbon Monoxide (CO)
|
||||
- **42602** - Nitrogen Dioxide (NO2)
|
||||
- **81102** - PM10 (coarse particulate matter)
|
||||
|
||||
**Why It Matters - Environmental Justice:**
|
||||
- **You cannot "self-care" your way out of breathing toxic air**
|
||||
- **PM2.5 reduces life expectancy** by months to years
|
||||
- **Environmental injustice** - Low-income communities disproportionately exposed
|
||||
- **Structural determinant** - ZIP code determines air quality, not personal choice
|
||||
- Measurable, actionable, preventable health risk
|
||||
|
||||
**Health Impacts:**
|
||||
- PM2.5: Mortality, cardiovascular disease, respiratory disease, cognitive decline
|
||||
- Ozone: Respiratory inflammation, asthma exacerbation
|
||||
- Long-term exposure in top decile can reduce life expectancy 1-3 years
|
||||
|
||||
**Unique Insight:**
|
||||
- Air quality is a **structural wellbeing constraint** like poverty
|
||||
- Policy visibility through monitoring (gaps in underserved areas = "data invisibility")
|
||||
- Environmental health reveals that wellbeing requires collective action, not just individual choices

## Integrated Wellbeing Framework
|
||||
|
||||
These five sources cover the critical dimensions of human wellbeing:
|
||||
|
||||
### 1. Economic Security (FRED)
|
||||
- Financial stress and debt burden
|
||||
- Employment quality (not just quantity)
|
||||
- Housing affordability
|
||||
- Income inequality
|
||||
|
||||
### 2. Health & Crisis (CDC WONDER)
|
||||
- Deaths of despair (overdoses, suicides)
|
||||
- All-cause mortality trends
|
||||
- Community-level health breakdown
|
||||
- Leading indicators of social collapse
|
||||
|
||||
### 3. Social Connection (Census ACS)
|
||||
- Structural isolation (living alone)
|
||||
- Time poverty (commute duration)
|
||||
- Digital divide (internet access)
|
||||
- Neighborhood characteristics
|
||||
|
||||
### 4. Work & Purpose (BLS JOLTS)
|
||||
- Worker agency (quit rate)
|
||||
- Economic opportunity (job openings)
|
||||
- Labor market dynamism
|
||||
- Voluntary vs involuntary separation
|
||||
|
||||
### 5. Environmental Health (EPA AQS)
|
||||
- Air quality and life expectancy
|
||||
- Environmental justice
|
||||
- Structural health determinants
|
||||
- Geographic inequality
|
||||

|
||||
|
||||
## Composite Wellbeing Indices
|
||||
|
||||
Based on the research, consider creating these composite indices:
|
||||
|
||||
### Financial Stress Composite (FSC)
|
||||
```
|
||||
FSC = weighted_average([
|
||||
TDSP (debt service ratio),
|
||||
DRCCLACBS (credit card delinquency),
|
||||
Eviction rates (external source),
|
||||
STLFSI4 (financial stress index)
|
||||
])
|
||||
```
|
||||
**Alert Thresholds:** >50 = elevated stress, >70 = crisis
|
||||
|
||||
### Crisis Alert Composite (CAC)
|
||||
```
|
||||
CAC = normalized_sum([
|
||||
Drug overdose deaths (CDC WONDER),
|
||||
Suicide rates (CDC WONDER),
|
||||
Long-term unemployment (FRED)
|
||||
])
|
||||
```
|
||||
**Leading indicator** - Spikes before economic metrics decline
|
||||
|
||||
### Community Health Composite (CHC)
|
||||
```
|
||||
CHC = inverse_weighted_average([
|
||||
Living alone rate (Census ACS),
|
||||
Long commute rate (Census ACS),
|
||||
No internet access (Census ACS)
|
||||
])
|
||||
```
|
||||
**Measures social infrastructure** - Connection and opportunity access
|
||||
|
||||
### Worker Agency Index (WAI)
|
||||
```
|
||||
WAI = weighted_average([
|
||||
Quit rate (BLS JOLTS),
|
||||
Job openings rate (BLS JOLTS),
|
||||
Inverse of long-term unemployment (FRED)
|
||||
])
|
||||
```
|
||||
**"Permission to Quit"** - Economic freedom and worker dignity
|
||||
|
||||
### Environmental Health Index (EHI)
|
||||
```
|
||||
EHI = inverse_weighted_average([
|
||||
PM2.5 concentration (EPA AQS),
|
||||
Ozone concentration (EPA AQS),
|
||||
Days exceeding AQI 100
|
||||
])
|
||||
```
|
||||
**Structural health determinant** - Collective wellbeing constraint
|
||||
|
||||
---
|
||||
|
||||
## Update Schedule Recommendations
|
||||
|
||||
**Weekly:**
|
||||
- FRED indicators (captures high-frequency economic stress)
|
||||
- EPA AQS (tracks air quality events)
|
||||
|
||||
**Monthly:**
|
||||
- FRED monthly indicators (unemployment, sentiment, saving rate)
|
||||
- BLS JOLTS (labor market health)
|
||||
|
||||
**Quarterly:**
|
||||
- FRED quarterly indicators (debt service, home prices)
|
||||
|
||||
**Annual:**
|
||||
- Census ACS (social wellbeing indicators)
|
||||
- CDC WONDER (mortality data has 1-2 year lag anyway)
|
||||
|
||||

|
||||
|
||||
## Data Quality Notes
|
||||
|
||||
### Completeness
|
||||
- **FRED:** Excellent (long time series, rarely missing data)
|
||||
- **CDC WONDER:** Good (cell suppression for privacy in low-count cells)
|
||||
- **Census ACS:** Excellent (comprehensive US coverage)
|
||||
- **BLS JOLTS:** Good (national reliable, state-level variable)
|
||||
- **EPA AQS:** Good (monitoring gaps in rural areas and some underserved communities)
|
||||
|
||||
### Timeliness
|
||||
- **FRED:** 1 week to 3 months depending on indicator
|
||||
- **CDC WONDER:** 1-2 year lag (deaths require coding)
|
||||
- **Census ACS:** 6-12 months (annual release)
|
||||
- **BLS JOLTS:** 6 weeks (faster than most labor data)
|
||||
- **EPA AQS:** Real-time to 6 months
|
||||
|
||||
### Geographic Granularity
|
||||
- **FRED:** National only for wellbeing indicators (some state data available)
|
||||
- **CDC WONDER:** National, State, County (excellent)
|
||||
- **Census ACS:** National, State, County, City, Census Tract (exceptional)
|
||||
- **BLS JOLTS:** National, limited State (national most reliable)
|
||||
- **EPA AQS:** Monitoring station (lat/long), aggregates to county/state
|
||||

|
||||
|
||||
## Known Limitations
|
||||
|
||||
### What These Sources CANNOT Tell You
|
||||
|
||||
1. **Individual-level wellbeing** - All are aggregated data (use surveys for individual experience)
|
||||
2. **Real-time wellbeing** - All have lag (1 week to 2 years)
|
||||
3. **Causation** - Correlation only (use experimental designs for causation)
|
||||
4. **Subjective experience** - Behavioral/objective only (use Gallup/Pew for perceptions)
|
||||
5. **International comparison** - US-only (use WHO GHO, UN SDG for global)
|
||||
|
||||
### Gaps to Fill with Additional Sources
|
||||
|
||||
- **Food insecurity** - USDA ERS needed
|
||||
- **Homelessness** - HUD Point-in-Time Count needed
|
||||
- **Substance abuse treatment** - SAMHSA needed
|
||||
- **Mental health service utilization** - Multiple sources needed
|
||||
- **Sleep quality** - CDC NHIS or NSF needed
|
||||
- **Volunteering/civic engagement** - AmeriCorps/Pew needed
|
||||

|
||||
## Philosophy: Knowing the Actual State of People
|
||||
|
||||
**Why this matters:**
|
||||
|
||||
Traditional wellbeing measurement focuses on:
|
||||
- GDP growth (economic output, not wellbeing)
|
||||
- Unemployment rate (misses underemployment, quality)
|
||||
- Survey happiness (subject to response bias, optimism)
|
||||
|
||||
**These new sources focus on:**
|
||||
- **Crisis indicators** (overdoses, suicides) - Reveal breakdown
|
||||
- **Behavioral truth** (quit rates, debt delinquency) - Actions > words
|
||||
- **Structural determinants** (air quality, commute times) - Constraints on flourishing
|
||||
- **Leading indicators** (financial stress before recession) - Early warning
|
||||
- **Geographic granularity** (county-level) - No one left invisible
|
||||
|
||||
**Core insight:**
|
||||
> "If we measure only GDP and unemployment, we will miss the slow-motion collapse of human thriving happening in plain sight."
|
||||
|
||||
**Purpose:**
|
||||
> "When we theorize or propose solutions, we are informed by the actual state of people - not abstractions, not averages, not GDP."
|
||||
|
||||

|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Test all update scripts** with valid API keys
|
||||
2. **Run initial data fetches** to populate data directories
|
||||
3. **Create composite indices** (FSC, CAC, CHC, WAI, EHI)
|
||||
4. **Build dashboards** for visualization
|
||||
5. **Establish alert thresholds** for crisis detection
|
||||
6. **Cross-reference** with Substrate Problems and Solutions
|
||||
7. **Add remaining sources** from research (food insecurity, homelessness, etc.)
|
||||
8. **Geographic analysis** - County-level maps of wellbeing
|
||||
9. **Time-series analysis** - Trend detection and forecasting
|
||||
10. **Integration** - Combine sources to find feedback loops and cascading failures
