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 city councilmember represents about the same number of constituents. In Chino, the City Council is responsible for drawing council districts. Redistricting is done using U.S. Census data, which is released around March 31, 2021 (Due to COVID-19, this date will likely be extended). For the City of Chino, the redistricting process must be completed by April 17, 2022.
