Small area (Census block) population counts by race and national origin are now available from the Census Bureau. These files are known as "Redistricting data" or the "PL-94-171 data". The files are based on 100 percent count and contain the most detailed information on the location of the total population by race and Hispanic/Latino origin, and population over the age of 18 (voting population) by race and Hispanic/Latino origin.
The PL-94-171 data constitute an important source for recent transportation planning concerns such as Environmental Justice (EJ) analysis because of the detailed race and ethnicity variables on the file. The file contains extensive data on race and ethnicity, so it can be used to analyze the concentrations of minority population groups.
