Hawaii ( Hawaiian: Mokuʻāina o Hawaiʻi) is the newest of the 50 U.S. states (August 21, 1959), and is the only U.S. state made up entirely of islands. It occupies most of an archipelago in the central Pacific Ocean, southwest of the continental United States, southeast of Japan, and northeast of Australia. Hawaii’s natural beauty, warm tropical climate, inviting waters and waves, and active volcanoes make it a popular destination for tourists, surfers, biologists, and volcanologists alike. Due to its mid-Pacific location, Hawaii has many North American and Asian influences along with its own vibrant native 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.
The state encompasses nearly the entire volcanic Hawaiian Island chain, 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 (from the northwest to southeast) Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and Hawaiʻi. The last is by far the largest and is often called "The Big Island" to avoid confusion with the state as a whole. The archipelago is physiographically and ethnologically part of the Polynesian subregion of Oceania.
U.S. President Barack Obama was born and spent much of his youth in Hawaii; he is the only president to hail from the state.
