Unlike most states in the U.S., Alaska is not divided into counties; instead, it is divided into boroughs. Alaska is divided into 1 Unorganized Borough and 19 organized boroughs. The region not part of any organized borough is called the Unorganized borough. The “Unorganized Borough” covers over half of Alaska’s area (970,500 km2). The U.S. Census Bureau, in cooperation with the state, further divides the Unorganized Borough into 11 census areas in the state for the purpose of statistical analysis. Census areas and Boroughs are treated as county-level equivalents by the Census Bureau. The 16 boroughs of Alaska cover the more densely part of Alaska and function similarly to counties in other states. Organized boroughs can be further divided into four different classes: unified home rule, Non-Unified home rule, first-class and Second class.
