For information on the Senate Districts during the transitional 2023-2024 Session please go here:
Senate districts established by the California Citizens Redistricting Commission (CRC) in 2021.
Even numbered Senate districts change with the 2022 election cycle.
Odd numbered Senate districts change with the 2024 election cycle.
These Senate districts will be in place until after the 2030 Census and the Citizens Redistricting Commission creates new ones. Population data on this page uses the Census Bureau's P.L. 94-171 Redistricting Data file, adjusted to reflect certain incarcerated persons at their last residential address.
