The population of the 6th district is highly educated– nearly 95% of adults have a high school diploma and more than 50% have a college degree, both of which are far above the national average. Many of the state’s highest-ranked public school districts are located within 6th, including the Naperville, Barrington, Indian Prairie, and St. Charles school districts.

The 6th district is also home to many colleges and universities, including North Central College, Benedictine University, Wheaton College, and the College of DuPage.

With several highly-regarded hospitals and hundreds of specialty clinics and physicians’ groups, the 6th district has excellent health care resources.

However, many people within the 6th district lack access to affordable care. According to Census Bureau estimates, more than 40,000 people in the district, including nearly 7,000 children, do not have health care.

Republican efforts to repeal the Affordable Care Act have put thousands more at risk of losing their health coverage. More than 66,000 people in the 6th district could lose their health insurance if Republicans are successful in eliminating health care exchanges and Medicaid expansion.
