Creates provisions for redistricting federal congressional seats

HB 3487 establishes Missouri's congressional district boundaries using U.S. Census data, specifying which 2010 and 2020 census blocks and voting districts (VTDs) form each district. It sets effective dates for different district configurations, applying specific boundaries for elections from the 108th through the 121st Congress. The bill directly affects Missouri voters by determining which geographic areas elect representatives to the U.S. House of Representatives under the defined district maps.
