Illinois’s first congressional district is a congressional district in the U.S. state of Illinois. Based in Cook County, the district includes much of the South Side of Chicago, and continues southwest to Joliet.
From 2003 to early 2013 it extended into the city’s southwest suburbs until reaching the border of Will County, and covered 97.84 square miles (253.4 km2), making it one of the 40 smallest districtsin the U.S. (although there are four smaller districts in Illinois). The district had a population that was 65% African American, the highest percentage of any congressional district in the nation. It includes the home of former President Barack Obama.
Since redistricting by the state legislature after the 2010 census, since January 3, 2013 it is a majority-minority district, now with 51.3% African American, 40.6% white, and 9.8% Hispanic population. The district is represented by Democrat Bobby Rush, who was re-elected in 2016, and has been elected continuously in the 1st district since 1992.
