Illinois Redistricting

Welcome to the Illinois legislative redistricting website. The redistricting process is vital to our democracy, designed to reflect the population of Illinois as it has evolved over the past decade.

We have developed this site in order to provide to the public basic information about the redistricting process. Here you will find information on the committee’s schedule of public hearings, links to relevant material, and much more. This site will also be regularly updated to help residents get the facts, engage with the process, and share thoughts.

We want to thank you for your participation and encourage your further input in this important process.

If you have any questions, you can contact us at: redistrictingcommittee@hds.ilga.gov.
