The statistical data matches up with the geographic data at several different levels. The main levels of interest in district drawing are counties, voter precincts, and census blocks. These three main levels have a nesting relationship, i.e. counties are comprised of voter precincts that, in turn, are comprised of census blocks. Each level covers the entire territory of the state, that is, there is no point within the state's boundaries that cannot be assigned to each of the three levels. These files can be used with geographic information system software.
Layers are in shapefile format.
See the attribute documentation for more detailed information about the contents of each layer. These errors have been corrected in the file linked above. This data corresponds with block level geography, the lowest level tabulated by the Census Bureau, and that at which districts are ultimately defined. This early release of 2000 census statistics includes only race and ethnicity breakdowns of total and voting age populations. In this data set, current as of February 2001, registered voters are broken down by party, race, gender, and age group.
