Geography Network's Free Redistricting Census 2000 TIGER/Line® Shapefiles: The Redistricting Census 2000 TIGER/Line files cover all counties, parishes, boroughs, census geographic areas and equivalent entities for each state, the District of Columbia, and Puerto Rico. The TIGER/Line files are a digital database of geographic features, such as roads, railroads, rivers, lakes, political boundaries, census statistical boundaries, etc. covering the entire United States. The database contains information about these features such as their location in latitude and longitude, the name, the type of feature, address ranges for most streets, the geographic relationship to other features, and other related information. They are the public products created from the Census Bureau's TIGER® (Topologically Integrated Geographic Encoding and Referencing) database of geographic information.

The coordinates in the TIGER/Line 2000 files are provided in the North American Datum of 1983 (NAD83). The data layers are being delivered in industry-standard shapefile format so they are easily accessible with GIS software products, such as ESRI's ArcView GIS and ArcExplorer. ArcExplorer is available as a free download.
