Languages Indigenous to the Nicobar Islands are the five Nicobarese languages, which form part of the Austroasiatic language family and are spoken by about people, or 7.6% of the population of the union territory. The Andaman Islands are home to about a dozen endangered or extinct Andamanese languages, which constitute at least two families that are unrelated to each other or to any other language group. The majority of the population, however, are speakers of immigrant languages. These include Bengali (the first language of 28.5% of the inhabitants of the union territory), Tamil (15.2%), Telugu (13.2%), Hindi (12.9%), Malayalam (7.2%). Sadri (5.5%), and Kurukh (4%). Hindi is the official language of the Andaman and Nicobar Islands, while English is declared an additional official language for communication purposes. Religion 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. Administration In 1874, the British had placed the Andaman and Nicobar Islands in one administrative territory headed by a Chief Commissioner as its judicial administrator. On 1 August 1974, the Nicobar islands were hived off into another revenue district with district headquarters at Car Nicobar under a Deputy Commissioner. In 1982, the post of Lieutenant Governor was created who replaced the Chief Commissioner as the head of administration. Subsequently, a "Pradesh council" with Councillors as representatives of the people was constituted to advise the Lieutenant Governor. The Islands sends one representative to Lok Sabha from its Andaman and Nicobar Islands (Lok Sabha constituency).
