The Uninsured in Illinois

Prior to implementation of the ACA in 2014, nearly 1 out of every 7 working age adults in Illinois lacked health insurance despite the fact that the majority of them are working full time. Slightly more than 40% of Illinois' 1.2 million eligible uninsured residents were enrolled by April 2014: 287,000 in Medicaid and 217,000 in the Marketplace. Data can help us all understand who the uninsured are, where are they live and work, to help us connect them to coverage and bring Illinois closer to ensuring healthcare for all.


What We Know About the Uninsured

Uninsured residents are unevenly distributed across the state. Data by census tract allows us to see at a granular level the areas where clusters of uninsured can be found. Demographic details available at the PUMA level from the American Community Survey give us a richer understanding of who are the people among us who lack health insurance, so we can better attempt to connect them to coverage.
