The Unorganized Borough is composed of the portions of the U.S. state of Alaska which are not contained in any of its 19 organized boroughs. While referred to as the "Unorganized Borough," it is not a borough itself, as it forgoes that level of government structure. It encompasses nearly half of Alaska's land area, , an area larger than any other U.S. state, and larger than the land area of the smallest 16 states combined. As of the 2020 U.S. Census, it had a population of 77,157, which was 10.52% of the population of the state. The largest communities in the Unorganized Borough are the cities of Bethel, Unalaska, and Valdez. Overview This vast area has no local government other than that of school districts and municipalities within its limits. Many of the villages do have tribal governments, however. Except within some incorporated cities, all government services in the Unorganized Borough, including law enforcement, are provided by the state or by a tribal government. School districts in the Unorganized Borough are operated either by cities, in those limited instances when the city has chosen to undertake those powers, or through the general guidance of the state Department of Education under the auspices of Rural Education Attendance Areas. Census areas Unique among the United States, Alaska is not entirely subdivided into organized county equivalents. To facilitate census-taking in the vast unorganized area, the United States Census Bureau, in cooperation with the state, divided the unorganized borough into 11 census areas, beginning with the 1970 Census and undergoing border or name adjustments most recently in 2007, 2008, 2013, 2015, and 2019. |} History During the 1950s, when the push for the territory of Alaska to become a state was at its height, any municipal government was extremely limited and scattered. Territory-wide, there were no more than a few dozen incorporated cities, and a small handful of service districts, broken into public utility districts and independent school districts. The service districts were authorized by the territorial legislature in 1935 to allow unincorporated areas limited powers to provide services and to raise taxes for them. The United States Congress had forbidden the territory from establishing counties. The delegates of the convention which wrote the Alaska Constitution had, in fact, debated the merits of establishing counties, and had rejected the idea in favor of creating a system of boroughs, both organized and unorganized.
