Andaman and Nicobar Islands (ăn`dəmən, nĭk`ōbär), union territory (2001 provisional pop. 356,265), India, in the Bay of Bengal. Port Blair (1991 pop. 74,955), in the Andamans, is the capital. Comprising the Andaman Islands, or Andaman Archipelago (2,508 sq mi/6,496 sq km), in the north and the Nicobar Islands (707 sq mi/1,831 sq km) in the south, the territory chiefly exports tropical products and lumber. Tourism is economically important. The islands, less than 40 of which are inhabited and some of which are subject to volcanic eruptions, are administered by the home ministry in the central Indian government.

Known to Europeans since the 7th cent. A.D., the Andamans, consisting of some 300 islands, were the site of a British penal colony from 1858 to 1945. The population is made up of indigenous Negritos (numbering less than 1,000) and largely Bengali and Tamil settlers from the Indian mainland. Settlers greatly outnumber the indigenous peoples, hundreds of which died from epidemics in the late 19th cent. Some of the Negritos have preserved a Stone Age culture.

The Nicobars, which comprise 19 small islands, are separated from the Andamans by a channel that is 90 mi (145 km) wide. The native population is of Mongolic stock. The Nicobars became a British possession in 1869. Japanese forces occupied both archipelagos during World War II.

Since World War II and Indian independence, some of the islands have undergone significant population growth and economic development, include Indian military bases, and regular air and ship services connect the islands with the mainland. The islands were especially hard hit by the Dec., 2004, Indian Ocean tsunami, because of their relative closeness to the epicenter (off NW Sumatra) of the earthquake that caused the waves; some 3,500 people are believed to have died.

Andaman and Nicobar Islands

Union territory (pop., 2001: 356,152), India. It consists of two groups of islands in the Bay of Bengal about 800 mi (1,300 km) east of the Indian subcontinent and Sri Lanka; the total area is 3,185 sq mi (8,249 sq km). The chief islands are North Andaman, Middle Andaman, and South Andaman (known collectively as Great Andaman), and Little Andaman. The Nicobar group includes Car Nicobar, Camorta (Kamorta) and Nancowry, and Great Nicobar. Most of the population lives in the Andaman group. Port Blair on South Andaman, established by the British in 1858, is the territorial capital.
