Census TIGER/Line 2000 is available to download for Geography Network users. ESRI is making this extensive data set available to download in shapefile format at no cost, so they are easily accessible with GIS software products, such as ESRI's ArcView GIs and ArcExplorer. ArcExplorer is available to download for free.

American FactFinder
http://factfinder.census.gov/

Start with Basic Facts: Use the drop-down menus at the top of the FactFinder screen to select geography and theme for a static thematic map that can be printed or downloaded as a GIF. Maps with 1990 census data are available. The lowest level of geography available is state by county.

Thematic Maps reveal geographic patterns in statistical data. For example, a thematic map could show the population density of Iowa by census tract. To create a thematic map, choose a geographic area, then select the data to display. The default data set is the Census 2000 Redistricting Data (PL94-171), but you can select from Census 2000 or 1990 datasets as available. You can zoom in and recenter, choose which boundaries and features to display, and identify geographic areas and values.

Reference Maps display administrative and census boundaries, including tract, block group, block and street boundaries. You can choose which boundaries and features to display, zoom in and recenter, and zoom in on a specific address.

Both Thematic and Reference Maps can be printed or downloaded in GIF format. These maps present data for the United States and Puerto Rico only.
