Kiribati ( KIRR-i-BAS or KIRR-i-BAHT-ee), officially the Republic of Kiribati (Gilbertese: Ribaberiki Kiribati), is an island nation in the central Pacific Ocean. The permanent population is just over 100,000 (2011), more than half of whom live on Tarawa Atoll. The nation comprises 33 atolls and reef islands and one raised coral island, Banaba. They have a total land area of 800 square kilometres (310 sq mi) and are dispersed over 3.5 million square kilometres (1,351,000 square miles). Their spread straddles the equator and the 180th meridian, although the International Date Line is indented to bring the Line Islands in the same day as the Kiribati Islands. The International Date Line circumscribes Kiribati by swinging far to the east, almost reaching the 150°W meridian. Kiribati's easternmost islands, the southern Line Islands, south of Hawaii, have the most advanced time on Earth, UTC+14 hours.
Kiribati became independent from the United Kingdom in 1979. The capital and now most populated area, South Tarawa, consists of a number of islets, connected by a series of causeways. These comprise about half the area of Tarawa Atoll.
Kiribati is a member of the Commonwealth of Nations, the IMF and the World Bank, and became a full member of the United Nations in 1999.
