A new brief from the Urban Institute explores state variation in health insurance coverage changes during implementation of the primary health insurance coverage reforms of the Affordable Care Act (ACA) using data from the 2013 and 2017 American Community Survey. State variation is summarized using a typology that groups states according to their pre-ACA uninsurance levels, Medicaid expansion status, and efforts to encourage marketplace enrollment.
