Every ten years, districts must be redrawn so that each supervisorial district is substantially equal in population. This process, called redistricting, is important in ensuring that each board member represents about the same number of constituents. The San Bernardino County Board of Supervisors is responsible for drawing supervisorial districts. The Board of Supervisors has adopted an ordinance establishing an Advisory Redistricting Commission that is required to recommend to the Board of Supervisors a minimum of two possible supervisorial district maps.  Redistricting will be based on the 2020 U.S. Census data, which is anticipated to be released to the State on September 30, 2021. For San Bernardino County, the redistricting process must be completed by December 15, 2021.
