TIGER/Line Geodatabases are spatial extracts from the Census Bureau’s Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) System for use with geographic information systems (GIS) software. These files include a variety of national and state-based geodatabases for geographic boundaries and features. 

These files do not include demographic data, but they contain geographic entity codes that can be linked to the Census Bureau’s demographic data, available on data.census.gov.

Further details of the geographic boundaries and features can be found in the TIGER/Line Shapefiles technical documentation.
