What's changed in the 2000 version of the TIGER/Line files?
The 2000 TIGER/Line file format has only small changes from recent versions; however, the content of the files is significantly
improved because of the massive updating effort carried out in preparation for the 2000 Census. Refer to the web link below
for more information on these changes. The 2000 TIGER/Line files will contain a new geographic entity called
ZCTAs (ZIP Code Tabulation AreasTM). The test files and documentation for the 2000 TIGER/Line files are available at URL:
http://www.census.gov/geo/www/2k_TIGER/2000_tig.html
Note: There will be two releases of the TIGER/Line files from Census 2000: the Redistricting Census 2000 TIGER/Line files and Census 2000 TIGER/Line files.

The first release of the Census 2000 TIGER/Line files is specifically intended to support the needs of the
redistricting community. Because of the timing of this release, it will NOT include the ZIP Code Tabulation
Areas (ZCTAs TM ) nor the final update to the Census 2000 address range information. The following areas will not
be included in this release: American Samoa, Guam, Northern Mariana Islands, the Minor Outlying Areas
(Midway) and the Virgin Islands.
