Relating to the composition of the districts for the election of members of the United States House of Representatives from the State of Texas.

SB 4 is a redistricting bill that redraws the boundaries for Texas's congressional districts used in U.S. House elections. It directly affects Texas voters by determining which geographic areas elect their representatives in Congress starting with the 2026 election cycle. The bill establishes a new map for all 38 Texas congressional districts based on the latest census data, replacing the current district lines. This is a procedural change to the electoral map, not a policy affecting daily life or government programs.
