The ICPSR (Inter-University Consortium for Political and Social Research) database now includes multiple versions of the TIGER/Line Files.  TIGER (Topologically Integrated Geographic Encoding and Referencing) data files, formerly made available by the U. S. Census Bureau provide users with appropriate data to prepare maps through geographic information system (GIS) software packages.  The TIGER/Line file versions available via ICPSR include those covering 1990-2006.

The cartographic information supplied by the TIGER/Line files covers all counties and equivalent entities in the United States, Puerto Rico, and Island Areas.  Researchers use these data to create shapefiles that contain geographic attributes for points, lines, or polygons.  Once these files are load into GIS software, researchers can input subject matter data, such as Census population and housing information, as overlays on the maps.

The ICPSR (Inter-University Consortium for Political and Social Research) web page provides search and browsing access to abstracts and data sets in the world's largest archive of computerized social science data.  Search or browse title of study, principal investigator, words in abstract, or study number.  Browse major research categories.
