The Affordable Care Act (ACA) has led to historic reductions in racial disparities in coverage and access to health care since 2013. The insurance coverage gap between Black and White adults dropped by 4.7 percentage points during that time, while the difference between Hispanic and White uninsured rates fell 9 points. These coverage gains made it easier to access care, and both Black and Hispanic adults have also reported large decreases in cost-related access problems.

Black and Hispanic adults generally have reported lower uninsured rates and greater disparity reductions in states that expanded Medicaid under the ACA. For example, after Louisiana expanded Medicaid in mid-2016, the coverage disparity between Black and White adults narrowed considerably in comparison to Georgia, which has not yet expanded. Still, progress has largely stalled since 2016 as uninsured rates have risen for nearly all races and ethnicities.
