Affordable Care Act Has Led to Historic, Widespread Increase in Health Insurance Coverage

Historic gains in health insurance coverage have been achieved since the implementation of the Affordable Care Act (ACA). In this brief, we use new and previously published estimates from the National Health Interview Survey to examine gains in health insurance coverage for non-elderly adults from 2010 to 2015. We provide estimates of the uninsured rate over time by income, race, state Medicaid expansion status, age, and urban and rural residence.
