Census 2020 "Voting District" (VTD), or election precinct, geography are here; associated Census 2020 demographics arrive in August 2021.

California and Oregon did not participate. One result is that there will be no Census 2020 or ACS 2020 VTD data as released by the Census Bureau for nonparticipating states. Some Census 2020 (but not ACS 2020) election preceinct data can be developed for states not participating in the Census VTD program by aggregating census block data.  Voting district analysis is of interest for many reasons. Voting districts, or election precincts, are the lowest common denominator for most election areas -- from city council to the U.S. House of Representatives. Voting district (VTD) demographics and voting results are typically difficult to acquire, making analysis of voting districts a challenging task. In most states voting district geography is defined on a sub-state/county basis. Boundaries are subject to frequent change. Often shapefiles for use in GIS applications are unavailable or difficult to acquire. The combination of these issues, geography in shapefile format and VTD demographics/voter results, make analysis of VTDs challenging. This section illustrates how voting district (VTD) geography can be examined in context of other geography and how voting district demographics can be analyzed using GIS resources. These applications make use of Fairfax County, VA, part of the Washington, DC metro, but can be developed for most counties/areas across the U.S. This section knits together with these related sections: (some of these are older links/files based on Census 2010; this section updates soon) • Congressional Districts • State Legislative Districts • Citizen Voting Age Population Demographics - tract & block group • Citizen Voting Age Population Demographics - county & state • CVAP & Voter Demographics - characteristics of those voting in 2014 elections • America's Communities • Voter Mobilization Resources & Methods The Census 2010 population of Fairfax County, VA was 1,081,726 (2,767 persons per square mile).
