US Congressional Districts
The legislative districts contain the geographically defined territories used for representation in the California State Assembly, California State Senate and the U.S. House of Representatives from California. These three boundary layers were approved by the California Citizens Redistricting Commission in 2021 following the completion of the 2020 United States Census.
