Maps

The 2011-2021 maps should be referenced for finding current district information.

Every ten years the Illinois state legislature redraws state and local districts lines to break the state into districts based on data provided by the US Census Bureau. This process is called redistricting. Local population changes may impact the redistricting and can create new boundaries for County Board Districts and precincts. Learn more about the redistricting process.


The maps provided at the bottom of this page from 2022-2032 will take effect following the November 8, 2022 General Election.
