After the 2020 census, Oklahoma’s congressional redistricting process was conducted by the Republican-controlled state legislature, consistent with the state constitution, which assigns redistricting authority to the legislature subject to gubernatorial approval. Population changes required only modest adjustments to Oklahoma’s five U.S. House districts. During a November 2021 special session, lawmakers passed House Bill 1005, which slightly reconfigured district boundaries while largely preserving the prior map’s structure. Governor Kevin Stitt signed the congressional plan into law on November 22, 2021, and it has been used in elections since 2022.

The state legislative redistricting process followed a similar legislative path but unfolded in stages. In May 2021, before final census data were released, the Oklahoma Legislature enacted interim state House and Senate maps using adjusted population estimates, with the understanding that revisions might be required. Once final census data became available, lawmakers revisited the maps during the November 2021 special session and adopted updated district boundaries for both chambers. These revised state House and state Senate plans were signed into law by Governor Stitt alongside the congressional map.
