## 2026-04 — Germany Evidence & Argumentation

### New Datasets — PR-00001 Proxy Data

**DE-Church-Exits** (get-de-kirchenaustritte)
- Annual EKD + DBK church exit counts 2010–2023
- All-time high 2022: ~903k exits. Hardcoded series (no public API).

**DE-Wellbeing** (get-de-wellbeing)
- Eurostat ilc_pw01 (life satisfaction mean 0-10): dropped from 7.5 (2013) → 6.5 (2022)
- Eurostat ilc_pw05 (high meaning in life %): dropped from 28.3% (2018) → 17.5% (2022) — **strongest signal**

**DE-Mental-Health** (get-de-mental-health)
- Gallup Engagement Index DE 2001–2023: 85% not/actively disengaged (consistent)
- Destatis suicide statistics 2010–2022 (hardcoded, ICD X60-X84)
- Eurostat EHIS depression rates: 8.5% (2014) → 9.1% (2019)

### PR-00001 Meaning Crisis — Evidence Expansion

**German Empirical Proxy Clusters Added**
- **Date:** 2026-04-22
- **Five proxy clusters:** Institutional trust loss (Kirchenaustritte, unions, Allensbach), mental health & work absence (DAK/TK Gesundheitsreport, BPtK, Burnout ICD F43.0), work meaning (Gallup Engagement Index DE since 2001, SOEP), social isolation (Destatis 42% single-person households, TU München loneliness study), value shift & youth (Shell Jugendstudie since 1953, World Values Survey, Eurobarometer)
- **Substrate-ready datasets identified:** Genesis-API (Destatis), DAK/TK reports, Gallup annual reports, SOEP via DIW
- **New connection added:** Oliver Nachtwey (*Abstiegsgesellschaft*), Milanovic (elephant curve) as structural drivers

**DE-Social-Isolation** (get-de-social-isolation)
- Eurostat lfst_hhnhtych: 21 years of single-person household data 2006–2025
- Latest (2025): 42.6% of all German households are single-person (17,742k of 41,663k)
- BMFSFJ/TU München Einsamkeitsstudie 2021: 27% lonely, 3.9M chronically lonely (hardcoded)

**DE-World-Values** (get-de-world-values)
- WVS Waves 5/6/7 for Germany (2006, 2013, 2018): postmaterialism, institutional trust, life satisfaction
- Postmaterialism: 19.4% (2006) → 25.8% (2018) (+6.4pp)
- Trust in political parties: 10.2% → 20.7% (still critically low)
- Life satisfaction: 7.5 → 7.1/10

### AR-00004 — Meaning Crisis Is Empirically Measurable

**New Argument Added**
- **Date:** 2026-04-22
- **Claim:** The meaning crisis is not merely philosophical — it is measurable through converging proxy data
- **Style:** Inductive — five independent data streams converging on the same conclusion
- **Key evidence:** Gallup Engagement Index (15/70/15% since 2001), DAK mental illness sick days (rank 4→1), Kirchenaustritte (~900k/yr), DGB -48% since 1991, Shell Jugendstudie
- **Related:** PR-00001, PR-00003
