Alaska is a non-contiguous US state on the northwest extremity of North America. It is in the Western United States region. The only other non-contiguous U.S. state is Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and it is the largest exclave in the world.

Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the sixth-largest subnational division in the world. It is the third-least populous and most sparsely populated U.S. state, but is, with a population of 736,081 as of 2020, the continent's most populous territory located mostly north of the 60th parallel, with more than quadruple the combined populations of Northern Canada and Greenland. The state contains the four largest cities in the United States by area, including the state capital of Juneau. The state's most populous city is Anchorage, and approximately half of Alaska's residents live within its metropolitan area. [1]

The Unorganized Borough [1] 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, 323,440 square miles (837,700 km2), and, as of the 2020 U.S. Census, it had a population of 77,157, which was 10.52% of the population of the state. Below are the the area comprising the Unorganized Borough.
