The portion of Alaska that is not within organized boroughs is covered by a single  \n“unorganized borough,” a legal entity administered by the State government. Because the unorganized borough is too  \nlarge geographically to provide a suitable basis for data analysis, the State of Alaska and the Bureau of the Census have divided it into “census areas”for statistical purposes. The census areas are identified in the list by “(CA)”following the name. Data systems that use the unorganized borough may code it as 999. Changes since the 1980s: Aleutian Islands (CA) (010) was replaced by Aleutians East (1978 October 23) and Aleutians West (CA) (1990 January 1); Kobuk (CA) (140) was replaced by Northwest Arctic (1986 June 2); Lake and Peninsula was established from part of Dillingham (CA) (1989 April 24). Wrangell City and Borough (02-275) was created from part of the former Wrangell-Petersburg CA (02-280) and part of Prince of Wales-Outer Ketchikan CA (02-201) (Meyers Chuck area)(2008 June 1). The remainder of the former WrangellPetersburg CA was established as the new Petersburg CA (02-195) (2008 June 1). Petersburg CA (02-195) was created from the remainder of the former WrangellPetersburg CA (02-280) when the new Wrangell City and Borough was created (2008 June 1). Prince of Wales-Hyder CA (02-198) was created from the remainder of the former Prince of Wales-Outer Ketchikan CA (02-201) after part (Outer Ketchikan area) was annexed by Ketchikan Gateway Borough (02-130) (2008 May 19), and part (Meyers Chuck area) included in the new Wrangell City and Borough (2008 June 1). Skagway Municipality (02-230) was created from part of the former Skagway-Hoonah-Angoon CA (02- 232) (2007 June 20). The remainder of the former Skagway-Hoonah-Angoon CA was established as the new Hoonah-Angoon CA (02-105).
