Hawaii

Hawaii ( hə-WY-ee; Hawaiian: Hawaiʻi [həˈvɐjʔi, həˈwɐjʔi]) 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 south of the Tropic of Cancer, one of only two states, along with Florida, with regions that have a tropical climate, 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.

Of the 50 U.S. states, Hawaii is the eighth-smallest in land area and the 11th-least populous; but with 1.4 million residents, it ranks 13th in population density. Two-thirds of Hawaii residents live on Oʻahu, home to the state's capital and largest city, Honolulu. Hawaii is one of the most demographically diverse U.S. states, owing to its location in the central Pacific and over two centuries of migration.
