The UA Census 2000 TIGER/Line files contain all Census 2000 entities included in the Census 2000 version of TIGER/Line, as well as Census 2000 vintage Urban Areas and Public Use Microdata Areas (PUMAs).
The primary differences in this version from the Census 2000 version is the inclusion of the Census 2000 Urbanized Areas (UAs), Urban Clusters (UCs), and Public Use Microdata Areas (PUMAs). The Census 2000 Urban Area and PUMA codes appear on Record Type A. The Urban/Rural Indicator fields moved from Record Type A to Record Type S.
The address ranges appearing in the UA Census 2000 TIGER/Line files are based upon the addresses in the final Master Address File (MAF) used for tabulating Census 2000. The UA Census 2000 TIGER/Line files coverage is as follows: all counties, parishes, boroughs, census areas and equivalent entities for each state, the District of Columbia, Puerto Rico and the Island Areas.
The TIGER/Line files are extracts of selected geographic and cartographic information from the Census Bureau's TIGER® (Topologically Integrated Geographic Encoding and Referencing) database.
There is one TIGER/Line file (in a compressed format) for each county or county equivalent. The file names consist of TGR + the 2-digit state FIPS (Federal Information Processing Standards) code + the 3-digit county FIPS code (i.e. TGR01031.ZIP for Coffee County, Alabama.) Each state folder contains individual county files as well as a Counts file. The county files are stored in compressed format and are compatible with PK Ware's PK Zip software. The COUNTSnn.TXT files (where "nn" is the state FIPS code) show the counts for the number of records for each record type by county for a state. If the count for a particular record type is 0, then that record type does not exist for that county.
The Census Bureau produces the TIGER/Line files in ASCII text format only; therefore, the data are NOT in the form of map images. To create maps with the TIGER/Line files, one would typically use a Geographic Information System (GIS) package or other mapping software.
Users are responsible for converting or translating the files into a format used by their specific software package. For information on how to use the TIGER/Line data with a specific software package one should contact the company that produced that software. For information on companies that sell products that use TIGER/Line data or that provide TIGER/Line related services, refer to the TIGER Website.
