- Abstract 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.
Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined
by local participants as part of the 2010 Census Participant Statistical Areas Program. The Census Bureau delineated the
census tracts in situations where no local participant existed or where all the potential participants declined to participate.
The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and
comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people,
with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to
population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending
on the density of settlement. Physical changes in street patterns caused by highway construction, new development, and so
forth, may require boundary revisions. In addition, census tracts occasionally are split due to population growth, or combined
as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features.
They may follow legal boundaries such as minor civil division (MCD) or incorporated place boundaries in some States and situations
to allow for census tract-to-governmental unit relationships where the governmental boundaries tend to remain unchanged between
censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In
a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census
tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census, the census
tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according
to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation
trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population
and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial
park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.
- Purpose 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.

- Maintenance and Update Frequency TIGER/Line Shapefiles are extracted from the Census MAF/TIGER database. No changes or updates will be made to this version
of the TIGER/Line Shapefiles. Future releases of TIGER/Line Shapefiles will reflect updates made to the Census MAF/TIGER
database.

The boundary information in the TIGER/Line Shapefiles are for statistical data collection and tabulation purposes only; their
depiction and designation for statistical purposes does not constitute a determination of jurisdictional authority or rights
of ownership or entitlement and they are not legal land descriptions.Coordinates in the TIGER/Line shapefiles have six implied
decimal places, but the positional accuracy of these coordinates is not as great as the six decimal places suggest.

Data Quality Information
- Attribute Accuracy Report
-
- Report 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.

- Logical Consistency Report 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.
- Completeness Report 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.
