In order to maintain a current geographic database from which to extract the TIGER/Line files, the U.S. Census Bureau uses various internal and external procedures to update the Census TIGER data base. While it has made a reasonable and systematic attempt to gather the most recent information available about the features this file portrays, the U.S. Census Bureau cautions users that the files are no more complete than the source documents used in their compilation, the vintage of those source documents, and the translation of the information on those source documents. The TIGER/Line files use a single field to identify places that are legal entities, and places that are statistical entities. The FIPS place code uniquely identifies a place within a state. If place names are duplicated within a state and they represent distinctly different areas, a separate code is assigned to each place name alphabetically by primary county in which each place is located, or if both places are in the same county, alphabetically by their legal descriptions (for example, "city" before "village"). |
The data was created to serve as base information for use in GIS systems for a variety of planning and analytical purposes. |

THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING, MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

SOURCE DATA PROCESSING PROCEDURES: The TIGER/Line files are extracts, from the Census TIGER (Topologically Integrated Geographic Encoding and Referencing) data base, of selected geographic and cartographic information. The U.S. Census Bureau s Census TIGER System automates the mapping and related geographic activities required to support the decennial census and sample survey programs of the U.S. Census Bureau starting with the 1990 decennial census. They include files for all counties and statistically equivalent entities in the United States and Puerto Rico. The initial sources used to create the Census TIGER data base were the USGS 1:100,000-scale Digital Line Graph (DLG), USGS 1:24,000-scale quadrangles, the U.S. Census Bureau s 1980 geographic base files (GBF/ DIME-Files), and a variety of miscellaneous maps for selected areas outside the contiguous 48 states. The DLG coverage is extensive, albeit of variable currency, and comprises most of the rural, small city, and suburban area of the TIGER/Line files. GBF/DIME-File coverage areas were updated through 1987 with the manual translation of features from the most recent aerial photography available to the U.S. Census Bureau. The U.S. Census Bureau has added to the Census TIGER data base the enumerator updates compiled during the Census 2000 census operations. The updates came from map annotations made by enumerators as they attempted to locate living quarters by traversing every street feature in their assignment area. The U.S. Census Bureau digitized the enumerator updates directly into the Census TIGER data base without geodetic controls or the use of aerial photography to confirm the features locational accuracy. The U.S. Census Bureau also made other corrections and updates to the Census TIGER data base supplied by local participants in various U.S. Census Bureau programs. Local updates originated from map reviews by local government officials or their liaisons and local participants in U.S. Census Bureau programs. Maps were sent participants for use in various census programs, and some maps were returned with update annotations and corrections. The U.S. Census Bureau generally added the updates to the Census TIGER data base without extensive checks. Changes made by local officials do not have geodetic control or coordinate system.
