This is the last boundary change until the next redistricting following the 2030 Census. All of the districts now reflect the 2021 Citizens Redistricting Commission(CRC) plan.

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.

This resource is a member of a series. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) System (MTS). The MTS represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. State Legislative Districts (SLDs) are the areas from which members are elected to state legislatures. The SLDs embody the upper (senate - SLDU) and lower (house - SLDL) chambers of the state legislature. Nebraska has a unicameral legislature, and the District of Columbia has a single council, both of which the Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation. A unique three-character census code, identified by state participants, is assigned to each SLD within a state. States that had SLDU updates between the previous and current session include Georgia, Minnesota, Montana, North Carolina, North Dakota, Ohio, Washington, and Wisconsin. In Connecticut, Illinois, Louisiana, New Hampshire, Wisconsin, and Puerto Rico, the Redistricting Data Program (RDP) participant did not define the SLDUs to cover the entirety of the state or state equivalent area. In the areas with no SLDUs defined, the code ""ZZZ"" has been assigned, which is treated as a single SLDU for purposes of data presentation. There are no SLDU TIGER/Line shapefiles for the Island Areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands). The state legislative district boundaries reflect information provided to the Census Bureau by the states by May 31, 2024. Note: Michigan is required by court order to redraw their state senate districts. However, these new SLDUs were not drawn by May 31, 2024, and will not be used until the next SLDU elections in 2026.
