List of boroughs and census areas in Alaska

From Wikipedia, the free encyclopedia

The U.S. state of Alaska is not divided into counties, as are 48 other states, but it is divided into boroughs; with Louisiana instead divided into parishes. Many of the more densely populated parts of the state are divided into 16 boroughs, which function somewhat similarly to counties in other states. However, uniquely, boroughs do not cover the entire land area of the state. The area not part of any borough is referred to as the unorganized borough.

For the 1970 census, the U.S. Census Bureau, in cooperation with the state, divided the unorganized borough into 11 census areas, each roughly corresponding to an election district. However, these areas exist solely for the purposes of statistical analysis and presentation. They have no government of their own.

Some areas in the unorganized borough receive limited public services directly from the Alaska state government, usually law enforcement from the Alaska State Troopers and educational funding.

Anchorage, Juneau, Sitka and Yakutat have consolidated city-borough governments.

Boroughs and census areas are both treated as county-level equivalents by the Census Bureau.

Current borough seats are given in parentheses, where they exist.

The links in the column FIPS borough code / FIPS census area code are to the Census Bureau information page for that borough or census area.

^ The FIPS borough code (or census area code) is the five-digit Federal Information Processing Standard (FIPS) code which uniquely identifies counties and county equivalents in the United States. The three-digit number is unique to each individual county within a state, but to be unique within the entire United States, it must be prefixed by the state code. This means that, for example, while Aleutians East Borough, Alaska is number 013, there is also an Arlington County, Virginia that is also 013, and a Bienville Parish, Louisiana that is also 013. While Valdez-Cordova Census Area, Alaska is number 261, Kenedy County, Texas is also number 261. To uniquely identify Aleutians East Borough, Alaska, you would need to use the state code of 02 plus the Borough code of 013. Thus the unique identifier for the entire United States for Aleutians East Borough, Alaska would be 02013, and for the Valdez-Cordova Census Area would be 02261, etc.
