The TIGER/Line Files are shapefiles and related database files (.dbf) that are
an extract of selected geographic and cartographic information from the U.S. Census
Bureau's Master Address File / Topologically Integrated Geographic Encoding and
Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national
file with no overlaps or gaps between parts, however, each TIGER/Line File is
designed to stand alone as an independent data set, or they can be combined to cover
the entire nation. Block Groups (BGs) are defined before tabulation block
delineation and numbering, but are clusters of blocks within the same census tract
that have the same first digit of their 4-digit census block number from the same
decennial census. For example, Census 2000 tabulation blocks 3001, 3002, 3003,..,
3999 within Census 2000 tract 1210.02 are also within BG 3 within that census tract.
Census 2000 BGs generally contained between 600 and 3,000 people, with an optimum
size of 1,500 people. Most BGs were delineated by local participants in the Census
Bureau's Participant Statistical Areas Program (PSAP). The Census Bureau delineated
BGs only where the PSAP participant declined to delineate BGs or where the Census
Bureau could not identify any local PSAP participant. A BG usually covers a
contiguous area. Each census tract contains at least one BG, and BGs are uniquely
numbered within census tract. Within the standard census geographic hierarchy, BGs
never cross county or census tract boundaries, but may cross the boundaries of other
geographic entities like county subdivisions, places, urban areas, voting districts,
congressional districts, and American Indian / Alaska Native / Native Hawaiian
areas. BGs have a valid code range of 0 through 9. BGs coded 0 were intended to only
include water area, no land area, and they are generally in territorial seas,
coastal water, and Great Lakes water areas. For Census 2000, rather than extending a
census tract boundary into the Great Lakes or out to the U.S. nautical three-mile
limit, the Census Bureau delineated some census tract boundaries along the shoreline
or just offshore. The Census Bureau assigned a default census tract number of 0 and
BG of 0 to these offshore, water-only areas not included in regularly numbered
census tract areas.
In order for others to use the information in the Census MAF/TIGER database in
a geographic information system (GIS) or for other geographic applications, the
Census Bureau releases to the public extracts of the database in the form of
TIGER/Line Shapefiles.

places, but the positional accuracy of these coordinates is not as great as the six
decimal places suggest.

Accurate against Federal Information Processing Standards (FIPS), FIPS
Publication 6-4, and FIPS-55 at the 100% level for the codes and base names. The
remaining attribute information has been examined but has not been fully tested for
accuracy.
The Census Bureau performed automated tests to ensure logical consistency and limits
of shapefiles. Segments making up the outer and inner boundaries of a polygon tie
end-to-end to completely enclose the area. All polygons are tested for closure. The
Census Bureau uses its internally developed geographic update system to enhance and
modify spatial and attribute data in the Census MAF/TIGER database. Standard geographic
codes, such as FIPS codes for states, counties, municipalities, county subdivisions,
places, American Indian/Alaska Native/Native Hawaiian areas, and congressional districts
are used when encoding spatial entities. The Census Bureau performed spatial data tests
for logical consistency of the codes during the compilation of the original Census
MAF/TIGER database files. Most of the codes for geographic entities except states,
counties, urban areas, Core Based Statistical Areas (CBSAs), American Indian Areas
(AIAs), and congressional districts were provided to the Census Bureau by the USGS, the
agency responsible for maintaining FIPS 55. Feature attribute information has been
examined but has not been fully tested for consistency. For the TIGER/Line Shapefiles,
the Point and Vector Object Count for the G-polygon SDTS Point and Vector Object Type
reflects the number of records in the shapefile attribute table. For multi-polygon
features, only one attribute record exists for each multi-polygon rather than one
attribute record per individual G-polygon component of the multi-polygon feature.
TIGER/Line Shapefile multi-polygons are an exception to the G-polygon object type
classification. Therefore, when multi-polygons exist in a shapefile, the object count
will be less than the actual number of G-polygons.
Data completeness of the TIGER/Line Shapefiles reflects the contents of the Census
MAF/TIGER database at the time the TIGER/Line Shapefiles were created.

The selected geographic and cartographic information (line segments) are
derived from the U.S. Census Bureau's Master Address File Topologically
Integrated Geographic Encoding and Referencing (MAF/TIGER) database.
TIGER/Line Shapefiles are extracted from the Census MAF/TIGER database by
nation, state, county, and entity. Census MAF/TIGER data for all of the
aforementioned geographic entities are then distributed among the shapefiles
each containing attributes for line, polygon, or landmark geographic data.
