Five-Domain Breakdown
The CDI is an equal-weight composite of five family-v1 distress domains. Each domain contributes 20% of the county score.
Methodology
The County Distress Index is a 0–100 composite score of household financial distress, computed for all 3,144 U.S. counties. Higher scores indicate greater distress. The index is built from five equal-weighted domains: Delinquency, Default & Legal, Debt Burden, Labor, and Safety Net & Buffer. Each domain is the mean of distress-oriented indicator percentiles; the CDI score is the equal-weight mean of those domain scores.
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. Data vintages range from 2023 to 2025 depending on source; full indicator-level vintage detail is in the methodology document.
