HB 1 Missouri House · 2025 2nd Extraordinary Session

Creates provisions for redistricting federal congressional seats

HB 1 establishes Missouri's congressional district boundaries for federal elections using U.S. Census data. It specifies that Missouri will maintain eight congressional districts for the 117th through 120th Congresses, with boundaries based on the 2020 Census. The bill sets effective dates for different district maps, ensuring districts align with population data after each census cycle. This directly affects Missouri voters by determining which district they are assigned to for federal elections.
