Changing Uninsured Rates by County — From 2013 to 2015

Millions of Americans have signed up for quality, affordable health insurance under the Affordable Care Act since the beginning of the first open enrollment period in October 2013. Since then, uninsured rates have declined across the country, with a few exceptions. This page contains three interactive maps you can use to explore the changing uninsured landscape.

The Enroll America/Civis Analytics uninsured model provides our best estimate of uninsured rates by geography and demographic group. For smaller geographies — such as ZIP codes and counties — and demographic groups that contain fewer people, Enroll America’s estimates may show increased variation from the actual uninsured rate in these areas.
