US State Hawaii
Hawaii is the 50th and most recent state to have joined the United States, having received statehood on August 21, 1959. Hawaii is the only U.S. state located in Oceania, the only U.S. state located outside North America, and the only one composed entirely of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean. The state encompasses nearly the entire volcanic Hawaiian archipelago, which comprises hundreds of islands spread over 1,500 miles (2,400 km). At the southeastern end of the archipelago, the eight main islands are—in order from northwest to southeast: Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and the Island of Hawaiʻi. The last is the largest island in the group; it is often called the "Big Island" or "Hawaiʻi Island" to avoid confusion with the state or archipelago. The archipelago is physiographically and ethnologically part of the Polynesian subregion of Oceania. Hawaii's diverse natural scenery, warm tropical climate, abundance of public beaches, oceanic surroundings, and active volcanoes make it a popular destination for tourists, surfers, biologists, and volcanologists. Because of its central location in the Pacific and 19th-century labor migration, Hawaii's culture is strongly influenced by North American and East Asian cultures, in addition to its indigenous Hawaiian culture. Hawaii has over a million permanent residents, along with many visitors and U.S. military personnel. Its capital is Honolulu on the island of Oʻahu. Hawaii is the 8th-smallest and the 11th-least populous, but the 13th-most densely populated of the 50 U.S. states. It is the only state with an Asian plurality. The state's oceanic coastline is about 750 miles (1,210 km) long, the fourth longest in the U.S. after the coastlines of Alaska, Florida, and California. The Hawaiian islands were formed by volcanic activity initiated at an undersea magma source called the Hawaii hotspot. The process is continuing to build islands; the tectonic plate beneath much of the Pacific Ocean continually moves northwest and the hot spot remains stationary, slowly creating new volcanoes. Because of the hotspot's location, all currently active land volcanoes are located on the southern half of Hawaii Island. The newest volcano, Lōʻihi Seamount, is located south of the coast of Hawaii Island. Because the islands of Hawaii are distant from other land habitats, life is thought to have arrived there by wind, waves (i.e. by ocean currents) and wings (i.e. birds, insects, and any seeds they may have carried on their feathers). This isolation, in combination with the diverse environment (including extreme altitudes, tropical climates, and arid shorelines), allowed for the evolution of new endemic flora and fauna. Hawaii has more endangered species and has lost a higher percentage of its endemic species than any other U.S. state. The extant main islands of the archipelago have been above the surface of the ocean for fewer than 10 million years; a fraction of the time biological colonization and evolution have occurred there. The islands are well known for the environmental diversity that occurs on high mountains within a trade winds field. On a single island, the climate around the coasts can range from dry tropical (less than 20 inches or 510 millimeters annual rainfall) to wet tropical; on the slopes, environments range from tropical rainforest (more than 200 inches or 5,100 millimeters per year), through a temperate climate, to alpine conditions with a cold, dry climate. The rainy climate impacts soil development, which largely determines ground permeability, affecting the distribution of streams and wetlands.
The US State Hawaii occupies 16,634 m², about 0,18 % of the total territory of the USA of 9,148,020 m². The total population of the US State Hawaii with 1,427,538 inhabitants (in 2017) has already increased by 17,83 % in this millennium. Almost 40 years ago there were 462,847 fewer people. The capital Honolulu alone has 351,024 inhabitants.
