Redistricting is the regular process of adjusting the lines of voting districts in accordance with population shifts. In California, public agencies and other organizations must redivide (or redraw) the lines of their districts every ten years once the results of the Census are released so that each district is substantially equal in population. This ensures that each elected official represents about the same number of constituents.

In Marin County, the Board of Supervisors is responsible for drawing supervisorial districts based on U.S. Census data and input from Marin County residents. All district lines must be reviewed to meet strict requirements for population equality, voting rights protections, and in accordance with the California FAIR MAPS Act. Our redistricting process must be completed by the end of 2021.
