Redistricting is the once-a-decade process of redrawing the political boundaries for elective offices after the U.S. Census.
Redistricting is the regular process of adjusting the lines of voting districts in response to accordance with population shifts within the County. Every ten years, supervisorial districts must be redrawn so that each district is substantially equal in population. This process is important in ensuring that each Supervisor represents about the same number of people. Redistricting is done using U.S. Census data, which is expected to be released by September 30, 2021.
In addition to being substantially equal in population, any supervisorial district boundaries must comply with voting rights laws. The California Voting Rights Act requires more than 500 jurisdictions in California to redistrict in 2021-2022.
