TIGER/Line Files at ICPSR (ICPSR 166)
Principal Investigator(s): Inter-university Consortium for Political and Social Research
This Web site was developed by the Inter-university Consortium for Political and Social Research to provide online access to various versions of the TIGER/Line files. The Census TIGER/Line files are, in total, an extract of selected geographic and cartographic information from the Census Bureau's TIGER (Topologically Integrated Geographic Encoding and Preferencing) database. The TIGER/Line files are a digital database of geographic features, such as roads, railroads, rivers, lakes, legal boundaries, census statistical boundaries, etc. covering the entire United States. These files contain 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. These files are not graphic images of maps, but rather digital data describing geographic elements found in every county and statistically equivalent entity. To make use of these data, a user must have mapping or Geographic Information System (GIS) software that can import TIGER/Line data.
These data are not available from ICPSR. Users should consult the data owners directly (via TIGER/Line Files at ICPSR) for details on obtaining the data and documentation.
