Loudoun County 2020 Census Blocks as adjusted by the Virginia Division of Legislative ServicesThe United States decennial census is the primary data source on population, age, and race used in redistricting. While there is no federal requirement that census data be used for redistricting, § 24.2-304.1 of the Code of Virginia requires local governments to use the most recent decennial population figures for such county, city, or town for the purposes of redistricting and reapportioning representation.
