2022 Redistricting Information

State law requires the Board of Supervisors to redistrict after each decennial census. Due to the Census delay, lawmakers passed SB1107, which extended the deadline to approve district changes to July 1, 2022. Because Supervisor District lines match Special Health Care and Community College Districts, changes made to Supervisor boundaries will be the same for these two special districts.

UPDATE: The Board of Supervisors approved a new map adjusting the boundaries of the county’s five supervisorial districts to account for population and demographic changes over the past decade.  The Board’s approval today comes after a three-week public comment period on five draft maps, a public hearing that detailed the methodology behind redistricting, and several rounds of revisions incorporating public feedback.  The new map will be effective on Jan. 1, 2024.  

Below are Geographic Information System Mapping datasets in shapefile format which the Maricopa County Recorder’s office maintains that are available for download.

Redistricting is required every decade following the Census.  For perspective, it may be helpful to review previous supervisorial boundaries.

Draft Maps


In accordance with a March 9, 2022 Board resolution, the Elections Department and Board consultants prepared five draft redistricting maps for consideration. The Board of Supervisors is requesting public comment on those maps.

There will be a public hearing on June 20, 2022 to discuss the Board’s redistricting methodology and initial public feedback. Residents will be able to comment during that meeting, or they can do so now using the form below.  A final map will be approved on or prior to the July 1, 2022 deadline.
