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.

BRITTON, S.D. — Marshall County ranks 3,065th among the nation's most financially distressed counties, according to the County Distress Index released this month by American Default Research.
The composite score of 20 out of 100 places Marshall in the "Healthy" zone. Among 3,144 U.S. counties scored, 3,064 counties rank more distressed. Within South Dakota, Marshall ranks 46th of 66 counties.
The index, which draws on 21 indicators from the U.S. Census Bureau, Bureau of Labor Statistics, Urban Institute and federal court filings, finds Marshall sitting near the national median across major distress indicators, with no single domain emerging as a clear driver.
"Marshall County is one of the steadier counties on the index — durable fundamentals across most domains. The risk pattern here is asymmetric: a single shock can change the picture quickly," said Ross Kilburn, founder of American Default Research.
