Arizona enacted new congressional and legislative districts on Jan. 24, 2022, after the state’s independent redistricting commission transmitted the maps to the secretary of state. Arizona was apportioned nine seats in the U.S. House of Representatives after the 2020 census, the same number it received after the 2010 census. The state also has 30 legislative districts, each of which elects one senator and two representatives.
The redistricting commission originally approved the maps on Dec. 22, 2021. Members unanimously approved the congressional lines and voted 3-2 in favor of the legislative plan with nonpartisan Chairwoman Erika Neuberg joining the two Republican members—David Mehl and Douglas York—in support and the two Democratic members—Shereen Lerner and Derrick Watchman—opposed.
Following their approval, the maps entered a review period during which time towns and counties could suggest minor administrative edits. On Jan. 18, the commission reconvened to discuss incorporating those edits and to certify the maps. The commission voted 3-2 to certify the congressional map on Jan. 18 and 3-2 in favor of the legislative map on Jan. 21 with Neuberg, Mehl, and York voting in support both times and Lerner and Watchman opposed.
