Data Matters was created to provide accurate substate data in accessible, meaningful formats as Illinois prepared for launch of the Affordable Care Act markeplace and statewide outreach and enrollment campaigns to help people get covered. The early maps and interactive presentations have been largely superceded by more-recent data. These earlier presentations are archived for historical reference.
Prior to the ACA, about 30% of Illinois’ uninsured lived in Chicago, the majority of them Black or Latino. The city also has the largest concentrations of immigrant populations, with more than 100 languages spoken, and is home to the great preponderance of the state’s undocumented residents. Prior to 2014, 840,000 working age adults in the eight-county Chicago metro area lacked health insurance. Chicago data stories »
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. See earlier data presentations grouped by topics such uninsurd rates, outreach and enrollments. Data topics »
