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.
The TIGER/Line Files include both incorporated places (legal entities) and census designated places or CDPs (statistical entities).
An incorporated place is established to provide governmental functions for a concentration of people as opposed to a minor
civil division (MCD), which generally is created to provide services or administer an area without regard, necessarily, to
population. Places always nest within a State, but may extend across county and county subdivision boundaries. An incorporated
place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are delineated for the decennial
census as the statistical counterparts of incorporated places. CDPs are delineated to provide data for settled concentrations
of population that are identifiable by name, but are not legally incorporated under the laws of the State in which they are
located. The boundaries for CDPs often are defined in partnership with State, local, and/or tribal officials and usually coincide
with visible features or the boundary of an adjacent incorporated place or another legal entity. CDP boundaries often change
from one decennial census to the next with changes in the settlement pattern and development; a CDP with the same name as
in an earlier census does not necessarily have the same boundary. The only population/housing size requirement for CDPs for
the 2010 Census is that they must contain some housing and population. The boundaries of all 2010 Census incorporated places
are as of January 1, 2010 as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The boundaries of
all 2010 Census CDPs were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP).

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.

description 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.

measure Description
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.
