2.     Geography issues:


The following are changes to county definitions from 1990 to 2000.



o        Denali Borough, Alaska (FIPS county code 068) (organized from part of Southeast Fairbanks and Yukon-Koyukuk Census Areas - FIPS county codes 240 and 290, respectively - on December 7, 1990)

o        Yakutat City and Borough, Alaska (FIPS county code 282) (organized from part of Skagway-Yakutat-Angoon Census Area - formerly FIPS county code 231 - on September 22, 1992)

For Table 1, only 2000 data are shown for these counties.


o        South Boston city, Virginia (FIPS county code 780) (this formerly independent city changed its legal status to "town" and became part of Halifax County - FIPS county code 083 - on June 30, 1995)


For Table 1, 1990 data for South Boston City was added to Halifax County.  For median travel time, the data for Halifax County (as defined in 1990) is reported.

o        The portion of Yellowstone National Park in Montana (FIPS county code 113) (until November 7, 1997, the Montana portion of the park was not in any county, and therefore the Census Bureau treated it as a separate geographic entity that was equivalent to a county in Montana for data presentation purposes; on that date, the Montana portion of the park became part of Gallatin and Park Counties - FIPS county codes 031 and 067, respectively)

Renamed, with new FIPS codes:

o        Dade County, Florida (FIPS county code 025) was officially renamed Miami-Dade County (FIPS county code 086) on November 13, 1997.

o        Skagway-Yakutat-Angoon Census Area (FIPS county code 231) was renamed Skagway-Hoonah-Angoon Census Area (FIPS county code 232) in 1992, after Yakutat City and Borough (FIPS county code 282) became a separate legal entity.
