The Affordable Care Act has helped reduce racial and ethnic disparities in health insurance coverage among nonelderly adults, according to recent research published in the American Journal of Public Health. In their analysis of data from the American Community Survey, researchers found that after the ACA's provisions went into effect in 2014, the percentage of uninsured adults dropped by 7.1 percentage points for Hispanics, 5.1 percentage points for blacks and 3 percentage points for whites. Coverage gains also were greater in states that expanded their Medicaid programs, the study notes. Study (subscription required)
