  • County Redistricting

    May 4, 2022, UPDATE: The Board of Supervisors at its May 3 meeting unanimously approved the recommendation of the County Redistricting Committee. Read more about the Board's vote in the County Administrator's newsroom. See the Maps tab below for the final, approved maps. 


    Under Arizona law, the Pima County Board of Supervisors is required to undergo redistricting every 10 years following the release of decennial census population estimates and adopt new district lines for the purpose of balancing the population of each district to within 10 percent.

    With the delayed release of Census population data this year, the Arizona State Legislature amended the statute to extend the redistricting deadline to July 1, 2022.  The Pima Community College Governing Board uses the same district lines as the Board of Supervisors and will follow any new lines approved.

    In the last redistricting effort in 2011, the Census data estimated a total population of 980,263 for Pima County. The recent 2020 Census data now shows an estimated total population of 1,043,433. In regard to supervisorial districts, District 2 experienced the least growth, Districts 1 and 4 grew the most and District 5 was the only district to lose population. District 4, the highest populated district, is almost 16 percent higher than the lowest populated district, District 5. This exceeds the required statutory 10 percent threshold, which in turn requires the BOS to redistrict lines to balance the population to no more than a 10 percent difference.

    At their December 7, 2021 meeting, the Board approved establishing a Redistricting Advisory Committee, with each Supervisor appointing one representative to serve.  The committee met between February 2022 and April 2022.

    The public can also submit questions and comments via the redistricting feedback form. COMMENTS ARE NOW CLOSED. 

    On April 12, 2022, the Committee completed its work and unanimously voted to recommend redistricting map 2b2a to the Board of Supervisors.  The recommended map is scheduled to be considered by the Board at their May 3, 2022 public meeting.
