The NHGIS specifically provides spatially aggregated census data: data summarizing individuals within particular areas, such as states or counties, where the "individuals" might be persons, housing units, farms, libraries, newspapers or any other features that were at some point counted in a U.S. census. No individual-level records, with or without personally identifiable information, are included anywhere in the NHGIS.
The U.S. Geological Survey's TIGER/line files constitute a digital base map of the entire United States. These files include spatial data for such geographic features as roads, railroads, waterways, and political and census boundaries (e.g., boundaries of tracts and block groups). find in the Library
