The Geography Division of the U.S. Census Bureau has released two sets of Topologically Integrated Geographic Encoding and Referencing products: the 2013 TIGER/Line shapefiles and the TIGER geodatabases. Both are extracts of the Master Address File/TIGER database and can be used with Geographic Information System software to map census geographic areas and features such as roads and rivers.
The TIGER/Line shapefiles are updated yearly, and this version includes a new coastline feature. The TIGER geodatabases include national- and state-based files often requested by customers and provide the ability to download multiple layers in a single file. Both the 2013 TIGER/Line shapefiles and the TIGER geodatabases can be downloaded from the website.
- Shapefiles are released in one of three types of coverages:
- Nation-based
- State-based
- County-based
- The table below lists each type of geography and the coverage(s) at which each is available.
