Census 2010 PL 94-171 Redistricting Dataset

Due to a large number of questions on how to use the PL 94-171 data, we have repackaged the census data for ease of use in GIS applications. Below you will find tract-level and block-level datasets for all of the PL 94-171 variables in tables 2, 4 and H1.

The files are zipped DBF tables, so you can import them into any popular GIS software. The files contain variables from the PL tables, as well as the following geographic identifiers: COUNTY, PLACE (block file) only, TRACT, BLOCK, BLOCK_KEY (block file only) and TRACT_KEY (tract file only).

The BLOCK_KEY field should be used to join the tables to a block-layer geography and the TRACT_KEY is used to join the tract tables to a tract-layer geography.
