Methodology
The County Distress Index is a 0–100 composite score of household financial distress, computed for all 3,144 U.S. counties. A score of 50 represents the national county median; higher scores indicate greater distress. The index is built from 21 indicators grouped into five statistically derived factors via principal component analysis (PCA); factor weights are proportional to each factor's share of explained variance (shown in the Five-Domain Breakdown above).
Data sources include the Urban Institute Debt in America (Equifax consumer credit panel), U.S. Census Bureau (American Community Survey 5-year, Small Area Income and Poverty Estimates, Business Formation Statistics), Bureau of Labor Statistics (Local Area Unemployment Statistics, Quarterly Census of Employment and Wages), U.S. Courts Administrative Office (F-5A bankruptcy filings), and HUD Fair Market Rents.
