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.

ALEDO, Ill. — Mercer County ranks 2,325th among the nation's most financially distressed counties, according to the County Distress Index released this month by American Default Research.

The index, which draws on 16 source indicators from the U.S. Census Bureau, Bureau of Labor Statistics, Urban Institute and federal court filings, finds Mercer sitting near the national median across major distress indicators, with no single domain emerging as a clear driver.
"Mercer County ranks in the second-least distressed fifth of U.S. counties. The state rank and domain mix give the county-level context," said Ross Kilburn, founder of American Default Research.
