District map

Redistricting
2020-2021
Illinois enacted a congressional map on November 24, 2021, after Gov. J.B. Pritzker (D) signed the proposal into law.[14] The Illinois State Senate voted 41-18 in favor of the map on October 28, 2021, followed by the Illinois House of Representatives voting 71-43 in favor on October 29, 2021.[15]
How does redistricting in Illinois work? The Illinois General Assembly is responsible for drawing both congressional and state legislative district lines. Both chambers of the state legislature must approve a redistricting plan. The governor may veto the lines drawn by the state legislature.[16]
In the event that both chambers of the state legislature do not approve a legislative redistricting plan, a backup commission must draw the lines. The majority and minority leaders of each chamber must appoint two members each to the commission (one legislator and one general citizen). Of the eight commission members, no more than four may belong to the same political party. In the event that these eight members cannot approve a plan, the Illinois Supreme Court must select two individuals (from different political parties) as potential tiebreakers. The secretary of state must then appoint one of these individuals to the backup commission to break the tie.[16]
The Illinois Constitution requires that state legislative districts be "contiguous and reasonably compact." There are no such requirements in place for the state's congressional districts.[16]
State law also mandates the establishment of state legislative districts "that allow racial or language minority communities to elect--or influence the election of--the candidates of their choice, even if no comparable district would be required by the federal Voting Rights Act."[16]
2020

2024

2010-2011
In 2011, the Illinois State Legislature re-drew the congressional districts based on updated population information from the 2010 census.
