JAN. 19, 2021 — Today the U.S. Census Bureau released the 2020 Census P.L. 94-171 geographic support products for Arkansas, Colorado, Maryland, New Jersey, and Virginia. These geographic products are provided to support redistricting efforts by state and local governments and contain newly created 2020 Census blocks and updated block groups, census tracts, voting districts, and current boundaries for legal governments and school districts referenced to Jan. 1, 2020.
Starting today and ending no later than Feb. 28, geographic products will be available on a flow basis for all states, the District of Columbia and Puerto Rico.
A 2010 to 2020 block crosswalk is also available to assist data users in comparing data between censuses. The shapefiles and geographic products are in the same format as 2010.
All products can be accessed from the Census Redistricting Data Program website.
