Reporter's Notes
Two data points in the indicator table worth a follow-up call.
According to U.S. Census Bureau, ACS 5-year (2023), Corson County's disability rate indicator is at the 44th percentile. American Default Research's CDI places every other indicator in the Safety Net & Buffer domain at or above the 95th percentile. The gap stands out against child poverty rate and median household income. Worth a call to the source agency or a local subject-matter contact in McIntosh.
According to U.S. Census Bureau, SAIPE (2023), 40% of children under 18 in Corson County live below the federal poverty line, versus 18% nationally. When a county's adult poverty rate is accompanied by a materially higher child poverty rate, the gap typically reflects single-parent household concentration or limited access to workforce-participation supports (childcare, transportation). Worth a call to the local school district's free-and-reduced-lunch coordinator or a regional United Way affiliate.

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), FRED/Equifax (subprime credit share), U.S. Census Bureau (American Community Survey 5-year, Small Area Income and Poverty Estimates), Bureau of Labor Statistics (Local Area Unemployment Statistics), U.S. Courts Administrative Office (F-5A bankruptcy filings), and HUD Fair Market Rents. Data vintages range from 2022 to 2026 depending on source; full indicator-level vintage detail is in the methodology document.
