⭐ Core Definition: Non-contiguous United States

The contiguous United States, also known as the U.S. mainland, officially referred to as the conterminous United States, consists of the 48 adjoining U.S. states and the District of Columbia of the United States in central North America. The term excludes the only two non-contiguous states and the last two to be admitted to the Union, which are Alaska and Hawaii, and all other offshore insular areas, such as the U.S. territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. The colloquial term Lower 48 is also used, especially in relation to Alaska. The term The Mainland is used in Hawaii. The related but distinct term continental United States includes Alaska, which is also in North America, but separated from the 48 states by British Columbia in Canada, but excludes Hawaii and all the insular areas in the Caribbean and the Pacific.

The greatest distance on a great-circle route entirely within the contiguous U.S. is 2,802 miles (4,509 km), coast-to-coast between Florida and Washington state; the greatest north–south line is 1,650 miles (2,660 km). The contiguous United States occupies an area of 3,119,884.69 square miles (8,080,464.3 km). Of this area, 2,959,064.44 square miles (7,663,941.7 km) is actual land, composing 83.65 percent of the country's total land area, and is comparable in size to the area of Australia. Officially, 160,820.25 square miles (416,522.5 km) of the contiguous United States is water area, composing 62.66 percent of the nation's total water area.

Non-contiguous United States in the context of Alaska

Alaska (/əˈlæskə/ ə-LASS-kə) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is 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 Asian 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. It is a semi-exclave of the U.S., and 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 seventh-largest subnational division in the world. It is the U.S. state with third-least populous, most sparsely populated, and closest to another continent which is Asia. With a population of 740,133 in 2024, it is the most populous territory in North America located mostly north of the 60th parallel, with more than quadruple the combined populations of Northern Canada and Greenland. Alaska contains the four largest cities in the United States by area, including the state capital of Juneau. Alaska's most populous city is Anchorage, and approximately half of Alaska's residents live within its metropolitan area.

Non-contiguous United States in the context of Hawaii

Hawaii (/hə.ˈw.i/ hə-WY-ee; Hawaiian: Hawaiʻi [hə.ˈvɐj.ʔi, hə.ˈwɐj.ʔi]) is an island state of the United States, in the Pacific Ocean about 2,000 miles (3,200 km) southwest of the U.S. mainland. One of the two non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, the only state in the tropics, and one of the two U.S. states, along with Texas, that were internationally recognized sovereign countries before becoming U.S. states.

Hawaii consists of 137 volcanic islands that make up almost the entire Hawaiian archipelago (the exception is Midway Atoll). Spanning 1,500 miles (2,400 km), the state is physiographically and ethnologically part of the Polynesian subregion of Oceania. Hawaii's ocean coastline is consequently the fourth-longest in the U.S., at about 750 miles (1,210 km). The eight main islands, from northwest to southeast, are Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and Hawaiʻi, after which the state is named; the last is often called the "Big Island" or "Hawaiʻi Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the largest protected area in the U.S. and the fourth-largest in the world.
