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. These data are freely available in ZIP compressed format. 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.
