Redistricting Information


Every ten years, districts must be redrawn so that each 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. In Stanislaus County, the Board of Supervisors is responsible for drawing supervisorial districts. Redistricting is done using U.S. Census data, which is released around March 31, 2021. For the County, the redistricting process must be completed by December 15, 2021

Redistricting determines which neighborhoods and communities are grouped together into a district for purposes of electing a board member. The Board of Supervisors will seek input in selecting the next district map for our supervisorial districts. You have an opportunity to share with the Board of Supervisors how you think district boundaries should be drawn to best represent your community.

To the extent practicable, district lines will be adopted using the following criteria:

  • geographically contiguous districts (each supervisorial district should share a common border with the next)
  • the geographic integrity of local neighborhoods or communities shall be respected in a manner that minimizes its division
  • geographic integrity of a city shall be respected in a manner that minimizes its division easily identifiable boundaries that follow natural or artificial barriers (rivers, streets, highways, rail lines, etc.), and (5) lines shall be drawn to encourage geographic compactness. In addition, boundaries shall not be drawn for purposes of favoring or discriminating against a political party
