The Commission uses the county-equivalent areas as defined in Federal
Information Processing Standards Publication 6-4, 1990 August 31.
However, since 1990, seven county-equivalent entities have changed.
- December 28, 1990 - Alaska - Denali Borough (02068) was established.
The new borough removes territory from the Yukon-Koyukuk Census
Area (02290) and an unpopulated part of Southeast Fairbanks Census
Area (02240).
- September 22, 1992 - Alaska - Yakutat Borough (02282) was established.
The new borough removes territory from the Skagway-Yakutat-Angoon
Census Area (02231). With the loss of Yakutat, that census area
is renamed Skagway-Hoonah-Angoon (02232).
- June 30, 1995 - Virginia - The independent city (county-equivalent)
of South Boston (51780) reverted to town status. South Boston
is an incorporated place within Halifax County (51083).
- November 13, 1997 - Florida - Dade County (12025) officially
changed its legal name to Miami-Dade County (12086).
- July 19, 1999 - Montana - Yellowstone National Park (30113)
shown as a county equivalent in 1990, is legally part of Gallatin
County (30031) and Park County (30067). Therefore , this eliminates
Yellowstone National Park as a county equivalent.
- July 1, 2001 - Virginia - The independent city (county-equivalent)
of Clifton Forge (51560) has reverted to town status. Clifton
Forge is now an incorporated place within Alleghany County (51005).
The FIPS county code of 560 for Clifton Forge, Virginia, is deleted.
- November 15, 2001 - Colorado - Broomfield County (08014) has
been created from parts of Adams (08001), Boulder (08013), Jefferson
(08059), and Weld (08123) counties.
