About Redistricting

Every ten years, after the preliminary data from the decennial U.S. Census is released, the Illinois General Assembly develops new legislative and Congressional districts for the state. The redistricting process is described in Section 3 of Article IV of the Illinois Constitution. This web site provides links to official sites and data related to redistricting in Illinois. For more information or to suggest a site, please contact Linda Zellmer, Government Information & Data Services Librarian, Western Illinois University.
