Andaman and Nicobar Islands is a union territory of India consisting of 572 islands, of which 38 are inhabited, at the junction of the Bay of Bengal and the Andaman Sea.
The territory is about 150 km (93 mi) north of Aceh in Indonesia and separated from Thailand and Myanmar by the Andaman Sea. It comprises two island groups, the Andaman Islands (partly) and the Nicobar Islands, separated by the 150 km wide Ten Degree Channel (on the 10°N parallel), with the Andaman islands to the north of this latitude, and the Nicobar islands to the south (or by 179 km). The Andaman Sea lies to the east and the Bay of Bengal to the west. The island chains are thought to be a submerged extension of the Arakan Mountains.
The territory's capital is the city of Port Blair. The total land area of the islands is approximately 8,249 km2 (3,185 sq mi). The territory is divided into three districts: the Nicobar District with Car Nicobar as its capital, the South Andaman district with Port Blair as its capital and the North and Middle Andaman district with Mayabunder as its capital.
The islands host the Andaman and Nicobar Command, the only tri-service geographical command of the Indian Armed Forces.
The Andaman Islands are also home to the Sentinelese people, an uncontacted tribe. The Sentinelese might be the only people currently known to not have reached further than a Paleolithic level of technology, however, this is disputed, as evidence of metalwork was found on their island.
Bengali is the most spoken language in the Andaman and Nicobar Islands. Hindi is the official language of the Andaman and Nicobar Islands, while English is declared an additional official language for communication purposes. As of the 2011 census, Bengali is spoken as the first language by 28.49 per cent of the Union Territory's population followed by Hindi (19.29%), Tamil (15.20%), Telugu (13.24%), Nicobarese (7.65%) and Malayalam (7.22%).
The majority of people of the Andaman and Nicobar Islands are Hindus (69.45%), with Christians forming a large minority of 21.7% of the population, according to the 2011 census of India. There is a significant Muslim (8.51%) minority.
