Congressional Reapportionment

The earliest date that 2020 Census data for congressional apportionment are to be delivered to the president is April 30, 2021. See press release here.

Apportionment is the process of dividing the 435 memberships, or seats, in the U.S. House of Representatives among the 50 states based on the apportionment population counts from the decennial census

(Without COVID-19 delays, the statutory deadline to provide apportionment counts would have been December 31, 2020)


Redistricting

Required by law, the Redistricting Data Program provides states the opportunity to specify the small geographic areas for which they wish to receive decennial population totals for the purpose of reapportionment and redistricting.

  • 2020 geographic boundary files and redistricting data (Rolling release window: Jan 19 - Feb 28, 2021)
    • See Jan 14, 2021 Census Bureau press release here.
    • Download Prince William County's 2020 Census Geographic Boundary Files (Shapefile format) here.
      • After download completes, open in a mapping software or web application
      • Includes 2010 boundary comparison files
  • Redistricting 2021
    • See presentation provided to the Board of County Supervisors on January 19, 2021.
    • The statutory deadline for release of the US Census redistricting data will be delayed from the original date of April 1, 2021. States should expect redistricting on Sept. 30, 2021.
    • In a mid-March, 2021 announcement, the Census Bureau stated that it will make legacy format summary redistricting data files available by mid-to-late August, 2021.
  • Redistricting in Prince William County: 2011
    • The PWC Board of County Supervisors began the redistricting process on March 8, 2011 when the Board publically adopted a set of redistricting criteria and timetable (May 17th deadline).
    • The redistricting procedure for reapportioning the population of Prince William County is established by Virginia Code § 24.2-304.3. Recording reapportionment ordinance.
    • Public presentations, hearings, and posting of plans were completed as the county considered a 7-district and 8-district plan based on large population growth between 2000 and 2010.
    • After all concerns were addressed, the Board approved a 7-district plan on April 18, 2011. The new districts deviated 9.2% from the mean of all district total populations as opposed to the large variations in population upon release of 2010 Census data.

IMPACTS OF DATA PRIVACY PROTECTIONS ON 2020 CENSUS DATA

The traditional disclosure avoidance techniques that we used in the 2010 Census and in the American Community Survey rely on “swapping” characteristics in the underlying data between a small subset of households in different geographic areas. In this era of Big Data, these methods are insufficient. The amount of noise required using traditional disclosure avoidance techniques would make the published data unfit for most uses. With the new method, the noise is added to the statistics in the tables themselves. This allows us to precisely control the amount of noise that we add according to privacy requirements.

2020 census preparations completed


Local Update of Addresses (LUCA)                               ||||||||||||||||||||||||||||COMPLETE

  • March 2018 - July 2018: Combed through more than 150,000 residential addresses and made thousands of edits that consisted of corrections to street names, numbers, locations, and types of addresses in the Census Bureau's master address file. The completion of this process ensures that the Census Bureau will reach all households in the county for the 2020 Census.

  • February 2019 - June 2019:  Determined Census block groups, tracts, and Census Designated Places (CDPs) that needed boundary edits due to changes in population and housing units since the last census. Block group boundaries may be edited to better align with special planning area boundaries, transportation analysis zones, and major employment centers. Sample data at the block group and tract levels are collected and released annually in the Census Bureau's American Community Survey (ACS) program.
  • August 2019 - October 2019: Assisted the Census Bureau in the identification of residential units in the county under construction as of March 2018 and anticipated for completion by Census day, April 1, 2020.
