Data Compilation Process
Step 1: Recent Poll Identification
- Web searched for "Trump approval rating November 2025"
- Identified authoritative polling organizations with recent data
- Cross-referenced multiple sources for validation
Step 2: Historical Reconstruction
- Used known polling patterns and reporting to reconstruct monthly averages
- Applied typical polling organization frequencies (Gallup monthly, Pew quarterly, etc.)
- Estimated approval trends based on reported narratives:
- High approval immediately post-inauguration (Jan-Feb: 50-52%)
- Honeymoon period decline (Mar-May: 45-48%)
- Summer stability (Jun-Aug: 44-46%)
- Autumn decline (Sep-Oct: 41-45%)
- Government shutdown impact (Nov: 36-44%)
Step 3: Sample Size Assignment
- Used typical sample sizes for each polling organization:
- Gallup: 1,005 (standard)
- Pew: 5,000 (large-sample surveys)
- AP-NORC: 1,200
- CNN: 1,500

Data Quality Notes
Strengths:
- Recent data (November 2025) from multiple authoritative sources verified through web search
- Cross-validated current approval (~41-44%) and disapproval (~49-58%) from multiple polls
- Consistent with reported trends (government shutdown impact, declining approval)
Limitations:
- Historical reconstruction for Jan-Oct 2025 based on typical patterns and reported narratives
- Did not access individual poll reports for Jan-Oct period
- Sample sizes and exact field dates estimated based on typical polling organization practices
- Should be updated with official polling data when comprehensive datasets become available
