Welcome to the Secretary of State's California Redistricting information page.
Redistricting Frequently Ask Questions
What is redistricting?
In order to get an updated count of the country's population, the U.S. Constitution requires a federal census every ten years. California uses census data to redraw the Congressional, State Senate, State Assembly, and State Board of Equalization districts based on population changes.
Who redraws district lines?
The independent California Citizens Redistricting Commission (CCRC) uses census data to redraw the Congressional, State Senate, State Assembly, and State Board of Equalization district boundaries. After the 2020 Census, the CCRC certified final district maps and delivered them to the Secretary of https://wedrawthelines.ca.gov/.
What did Prop. 50 do?
Proposition 50 was approved by voters at the November 4, 2025, Special Statewide Election. Under Prop. 50, California will temporarily use legislatively drawn Congressional district maps starting in 2026 and through 2030. These Congressional district maps will be used until the CCRC draws new maps following the 2030 U.S. Census.
Prop. 50 did not alter current State Senate, State Assembly, or State Board of Equalization district lines. Those lines that were drawn by the CCRC after the 2020 Census remain in effect.
Local district lines. The boundaries for local districts, such as county supervisorial or city council districts, are drawn by those governing bodies and not by the CCRC. Information about the local process can be found here: https://www.sos.ca.gov/elections/helpful-resources/redistricting.
What is the Secretary of State's role after receiving new maps from the CCRC?
The Secretary of State provides the CCRC maps to the California State Legislature and to California's 58 counties who are redrawing precincts within the new district boundaries and assigning voters to the updated precincts.
What does redistricting mean to voters?
After each federal census, there is some possibility that the districts for your Congressional, State Assembly, State Senate, and Board of Equalization will change, which means that your representatives in these elected offices may change.
When do the new district lines take effect?
After the next federal census in 2030, new district lines will take effect for the 2032 election cycle, and the then newly elected officials will take office after the November 2032 General Election.
