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. The effects of public policy measures, and of stalemates such as the 2015-16 Illinois budget crisis, can often best be visualized by presenting data on the results they bring about.

The Uninsured

Uninsured residents are unevenly distributed across the state. Mapping allows us to see where clusters of uninsured can be found and, as new data becomes available from the American Community Survey, to follow the effects of the changes in access to health insurance.
