Gera Coverage Index35 / 100US average — a coverage gap close to the US averageHow this index is calculated

The Gera Coverage Index weights each state's three real ACS uninsured rates (50% all-ages, 30% working-age 19–64, 20% children under 19) and scales the result to 0–100; higher means a wider coverage gap. Texas has the widest gap (GCI 70); Massachusetts the narrowest (12). The national index is 35.

Methodology

Uninsured rates are the published US Census Bureau American Community Survey (ACS) 1-year point estimates for 2024 (with 2023 for comparison), transcribed verbatim from the Census report “Health Insurance Coverage by State: 2023 and 2024” (ACSBR-024), Appendix Tables 2 (all ages), 3 (working-age adults 19–64) and 4 (children under 19). The Gera Coverage Index is a transparent weighted average of those three real rates per state (0.50 all-ages + 0.30 working-age + 0.20 children) scaled ×4 to a 0–100 range — no estimates or invented numbers are mixed in. State averages are not statements about any individual's coverage, and nothing here is medical advice. Reference period: 2024 ACS 1-year estimates.
