In the first half of 2021, one fifth of U.S. adults in non-Medicaid expansion states did not have health insurance. In comparison, just one in ten of U.S. adults in Medicaid expansion states were uninsured. There was a difference in the uninsured rate between these states even before Medicaid expansion, but the expansion due to ACA has made the gap much larger.
This statistic shows the percentage of adults aged 18-64 years without health insurance in the United States from 2010 to June 2021, by state Medicaid expansion status.
