The attribute data include FIPS place ID, name, and type of municipality. Boundaries are generalized from the original TIGER data.
Incorporated places recognized in decennial US census data products are those reported to the U.S. Census Bureau as legally in existence on January 1, 2000, under the laws of their respective states, as cities, boroughs, towns, and villages.
Census designated places (CDPs) are delineated for each 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.
These are generalized cartographic boundaries originally produced to support the spatial geographic infrastructure for certain mapping functions within the Census Bureau's American Fact Finder and in support of the LandView Geographic Data Viewer. The data are a generalized extraction from the Census Bureau's TIGER database. The suggested scale for use of these data is 1:5,000,000. The data were obtained from the US Census website.
These data are appropriate for use in regional thematic analysis. The data are not appropriate as a geodetic, legal or engineering base. The data set was not and is not intended as a substitute for surveyed locations, such as can be determined by a registered Public Land Surveyor. Although useful in a GIS as a thematic, reference, or base layer for maps, the data set has no legal basis in the definition of boundaries or property lines.

Map information is to be used at a scientifically and cartographically appropriate scale, that is, at a scale no greater than indicated on the map or as described in the documentation of the map or map data. Map information is not appropriate for, and is not to be used as, a geodetic, legal, or engineering base. Map information has no legal basis in the definition of boundaries or property lines and is not intended as a substitute for surveyed locations such as can be determined by a registered Public Land Surveyor.
The data do not replace the need for detailed site-specific studies.
