Redistricting

2020-2021

See also: Redistricting in Texas after the 2020 census

In August 2025, the Texas Legislature proposed a new congressional district map during special legislative sessions that prompted Democratic legislators to leave the state to prevent a quorum. Click here to read more about the 2025 Democratic walkout during mid-decade redistricting in Texas.

On August 20, 2025, the Texas House approved House Bill 4 containing a new congressional map by an 88-52 vote along party lines. On August 23, 2025, the Texas Senate approved the map by an 18-11 vote along party lines. Texas Gov. Greg Abbott (R) signed the new map into law on August 29, 2025. The bill text stated the new district boundaries would take effect for the 2026 elections.

Texas first enacted new congressional districts on October 25, 2021. The Senate released a proposed congressional map on September 27, 2021, and approved an amended version of the proposal on October 8, 2021. On October 13, 2021, the House Redistricting Committee approved an amended version of the congressional map, and both chambers of the legislature approved a finalized version of the map on October 18, 2021. The Senate approved the proposal in an 18-13 vote, and the House approved the bill in an 84-59 vote. Gov. Greg Abbott (R) signed the map into law on October 25, 2021. This map took effect for Texas' 2022 congressional elections.

How does redistricting in Texas work? In Texas, both congressional and state legislative district boundaries are drawn by the Texas State Legislature. These lines are subject to veto by the governor.

If the state legislature is unable to approve a state legislative redistricting plan, a backup commission must draw the lines (the backup commission is not involved in congressional redistricting). This backup commission, established in 1948, comprises the following members:

1. Lieutenant governor
2. Speaker of the Texas House of Representatives
3. Attorney general
4. State comptroller
5. Commissioner of the General Land Office

The Texas Constitution requires that state legislative districts be contiguous and "that they preserve whole counties when population mandates permit."

Following the 2010 United States Census, Texas gained four congressional seats. Texas' final congressional redistricting plan was approved by the Texas Legislature and signed by Gov. Rick Perry (R) in June 2013.
