Census 2000 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 a block-level dataset for all of the PL 94-171 variables. For each county, you will find four data files corresponding to the four tables of the pl. 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, TRACT, BLOCK, TRACTKEY, and BLOCKKEY. The BLOCKKEY field should be used to join the tables to a block-layer geography.
In addition, you may wish to download the statewide tract datasets. They have the same fields as above, with the exception of BLOCKKEY.
