Election results from Illinois State Board of Elections(https://www.elections.il.gov/ElectionOperations/ElectionVoteTotals.aspx)

Precinct shapefiles primarily from the U.S. Census Bureau's 2020 Redistricting Data Program Phase 2 release. The following counties used maps sourced from the respective county governments instead: DuPage, Kane, Kendall, Will.

Some counties used the Census Redistricting shapefiles as a starting point, but were corrected using PDF maps to reverse changes made since 2016. These include Champaign, Greene, Hancock, Kane, Knox, LaSalle, Lawrence, Mason, St. Clair, Will, and Winnebago Counties.
