2020 Census and redistricting

2020 Census

The United States Constitution requires the federal government to conduct a complete count and demographic information of everyone living in the country every ten years. This counting project, or “Federal Decennial Census,” is conducted by the “United States Census Bureau” and was last conducted in 2020. The Census Bureau expects to release data in September 2021, a delay of several months due to COVID-19. Find out more about the 2020 Census.


Following the release of 2020 Federal Decennial Census data, the boundary lines of various voting districts must be adjusted so that each district maintains a number of residents relative to other districts. This process is called “redistricting”.

In California, redistricting will involve the redrawing state legislative and congressional district lines. In San Francisco, redistricting will involve the redrawing Supervisorial district lines. See San Francisco’s current district map (PDF).

State and federal district lines

In November 2008, California voters passed the Voters FIRST Act, authorizing the creation of the state Independent Citizens Redistricting Commission (ICRC). In 2021-2022, the ICRC will redraw the lines of California’s Congressional, Senate, Assembly, and Board of Equalization districts. The ICRC, which will consist of 14 members (5 Republicans, 5 Democrats, and 4 not affiliated with either of those two parties), is expected to complete the state redistricting process by February 2022. Find out more about the ICRC.

Supervisorial district lines in San Francisco

Per the San Francisco Charter, when new census data indicates that the populations in San Francisco’s Supervisorial districts are uneven, the Director of Elections must inform the Board of Supervisors.  The Board of Supervisors must then convene a Redistricting Task Force (RTF) to adjust Supervisorial District lines. The RTF, which will consist of 9 members (the Mayor, the Board of Supervisors, and the Elections Commission each appoint 3 members), must complete this process by April 15 of the year in which the next scheduled election for members of the Board of Supervisors will be held. Since the next such election is scheduled for November 8, 2022, the RTF is expected to release revised local district maps by April 15, 2022.


Members of the public are encouraged to participate any meeting held by the San Francisco Redistricting Task Force — in addition to providing general comments, anyone is welcome to submit proposed boundary lines to any or all of the City’s Supervisorial districts.

Members of the public are also encouraged to participate in any “public input hearings” held by the California Independent Citizens Redistricting Commission. Get more information on how to participate in public input hearings.

Please note that the redistricting process for San Francisco Police Department Station Boundaries is not administered by the San Francisco Redistricting Task Force.  The San Francisco Police Department and San Francisco Police Commission administers the process for proposed updates to district station boundaries and the solicitation of public input.

Voting after redistricting

The boundaries of one or more of the districts in which you reside may change (like your supervisorial or congressional district). In that case, one or more of your political representatives could change. Find your current political representatives.

You will be able to review new voting district information at sfelections.org/mydistrict shortly after the Independent Citizens Redistricting Commission and the Redistricting Task Force complete their work in February 2022 and April 2022, respectively.
