Legislative Redistricting Data Setup

http://www2.census.gov/census_2010/01-Redistricting_File--PL_94-171/pl_part1_2010.sas has the best description of what the fields are in the file redistricting data files.  If you want to do additional investigation of this data, perhaps to look at the distribution of self-identified multi-racial individuals, the data files are ASCII CSV but do not have a header line with the field names, and can be very large, but you could turn them into a database and then  join them to the block geometry files.
