Medicaid Coverage Gap: Black Americans Left Behind
2.4M
Black Americans fell into the Medicaid coverage gap in states that have not expanded — losing access to subsidized coverage
The Affordable Care Act's Medicaid expansion was designed to cover adults earning up to 138% of the federal poverty line. In states that accepted expansion, uninsured rates for low-income adults dropped dramatically. But 10 states — all in the South or Midwest — have not expanded Medicaid as of 2024. In those states, adults earning between 0–100% of FPL often have no coverage option: they earn too much for traditional Medicaid, but too little to qualify for ACA marketplace subsidies (which start at 100% FPL). This 'coverage gap' has fallen disproportionately on Black Americans.
Of the approximately 2.4 million Black Americans in the coverage gap, the majority live in Texas, Georgia, and Florida. These are also states where the Black population is concentrated and where racial health disparities in maternal mortality, cardiovascular disease, and cancer outcomes are among the worst in the nation. Coverage gap status is directly correlated with delayed care, higher rates of preventable hospitalizations, and worse outcomes for chronic conditions.
Recent federal incentives — including enhanced matching funds for newly expanding states — have stalled politically. Proposed federal Medicaid spending caps and per-capita limits, if enacted, would accelerate coverage losses even in expansion states. The 2024 election cycle has made federal Medicaid cuts a live political risk for the first time since the ACA's passage.

Methodology
American Community Survey 1-year and 5-year estimates used for population and income-stratified demographic profiles. Medicaid expansion status from CMS.gov state-by-state expansion tracker, current as of January 2024. Coverage gap estimates follow KFF methodology: non-elderly adults (19–64) with family income below 100% FPL in non-expansion states, excluding those with other coverage (employer, Medicare, other Medicaid). Black population share of gap estimated using ACS race-by-income microdata. Uninsured time series from NHIS and ACS.
