Redistricting Information


Every 10 years, the County must reexamine its magisterial districts in order to ensure that the districts are evenly distributed, based on the U.S. Census results. Prince William County has experienced tremendous growth in the last 10 years, which necessitated changes to the magisterial districts in the County. Changes to magisterial districts enacted in 2011 are based on analysis of the population data from the 2010 U.S. Census.

The Constitution of Virginia requires the Board of County Supervisors to change it's district boundaries every 10 years in the year ending in one using the most recent decennial population figures. Therefore, the Board must embark on redistricting measures and is required to adopt a redistricting ordinance in 2021. The Virginia Redistricting Commission is responsible for redistricting the state congressional, state senate and state house districts.

To guide the county's redistricting efforts, the Board of County Supervisors adopted a set of criteria during their May 18 meeting. These criteria are a combination of legally required criteria and traditional districting principles that are recognized by the courts. Also, during the May 18 meeting, the Board agreed to use an independent contractor to help with the county's 2021 redistricting process and asked the contractor to provide options for seven and eight districts.
