2007 TIGER/Line® ShapefilesThe TIGER/Line Shapefiles are extracts containing selected geographic and cartographic information from the Census Bureau's MAF/TIGER® (Master Address File / Topologically Integrated Geographic Encoding and Referencing) database. The MAF/TIGER database was developed at the Census Bureau to support a variety of geographic programs and operations including functions such as mapping, geocoding, and geographic reference files that are used in decennial and economic censuses and sample survey programs. Spatial data for geographic features such as roads, railroads, rivers, and lakes, as well as legal and statistical geographic areas are included in the product. Other information about these features, such as the name, the type of feature, address ranges, and the geographic relationship to other features, also are included. The TIGER/Line Shapefiles are made available to the public and are typically used to provide the digital map base for a Geographic Information System or for mapping software.
The 2007 TIGER/Line Shapefiles contain current geographic areas (boundaries of governmental units as of January 1, 2007) and Census 2000 vintage geography. The shapefiles also contain some additional post January 1, 2007 feature updates reported in the Boundary and Annexation Survey (BAS). The 2007 TIGER/Line Shapefiles contain realigned street feature coordinates as a result of the MAF/TIGER Accuracy Improvement Project. The Census Bureau is providing a list of counties that have not been realigned via the MTAIP process.
TIGER/Line Shapefiles Frequently Asked Questions (FAQ) webpage .
Unlike the TIGER/Line files which were county based, the TIGER/Line Shapefiles are available to download by nation, state, county, or American Indian Area (AIA). For example, the state shapefile is nation based, therefore it will include all 50 states, District of Columbia, Puerto Rico and the Island areas. For more information about how to download the data, please refer to the organizational structure of the shapefiles and relationship files.

The relationship files provide additional attribute information for features and are available to download by county. A description of the relationship files and an entity relationship diagram that provides the association between the relationship files and the shapefiles is provided in [PDF] format. The description of the relationship files is also provided in [TEXT] format.
User Notes are provided to document updates and known data errors that exist in the 2007 TIGER/Line Shapefiles.
The 2007 TIGER/Line metadata in Extensible Markup Language (XML) format is included with each compressed TIGER/Line Shapefile.
The Spatial Metadata Identifier (SMID) in the All Lines shapefile identifies the source of the coordinates for each line segment and provides the link between the TIGER/Line Shapefile and the source and horizontal spatial accuracy information. Please note that the horizontal spatial accuracy, where reported in the metadata, refers to the realigned street features identified as matched to a positionally accurate source file with that accuracy. Individual feature-based horizontal spatial accuracy does not apply to the entirety of the TIGER/Line Shapefile.
The North American Datum of 1983 was used in the 48 contiguous states, the District of Columbia, Alaska, Hawaii, (only Oahu Island within Honolulu County, HI (15003)), Puerto Rico, the Virgin Islands of the United States, and the Pacific Island Areas. Even though a NAD83 PRJ file will accompany every TIGER/Line Shapefile, there are a few island areas in TIGER that have not gone through the NAD83 transformation process and are still in local astronomic datums. For detailed information regarding these exceptions please refer to the metadata that is included with each TIGER/Line Shapefile.
If you obtained the TIGER/Line Shapefiles directly from the U.S. Census Bureau and need further information concerning the content of the files, please contact the Geographic Products Branch, Geography Division at geo.tiger@census.gov. For information concerning the subject matter and contents of the TIGER/Line Shapefiles obtained from a source other than the U.S. Census Bureau, please contact that source.
