As of 2011update Census of India, the population of the Union Territory of Andaman and Nicobar Islands was 379,944, of which 202,330 (53.25%) were male and 177,614 (46.75%) were female. The sex ratio was 878 females per 1,000 males. Only 10% of the population lived in Nicobar islands.

The original population of the islands – the Great Andamanese, the Onge, the Jarawa and the Sentinelese, were estimated to be around 5,000 150 years ago. The population of islands increased massively due to the colonisation policy of Govt of India into islands under Jawaharlal Nehru in the late 1960s, that brought settlers from other parts of the country.

The areas and populations (at the 2001 and 2011 Censuses) of the three districts are:

Name	Area (km2)	Population Census 2001	Population Census 2011	Capital
Nicobar	1,765	42,068	36,842	Car Nicobar
North and Middle Andaman	3,536	105,613	105,597	Mayabunder
South Andaman	2,640	208,471	238,142	Port Blair
Totals	7,950	356,152	380,581

There remain approximately 400–450 indigenous Andamanese in the Andaman islands, the Jarawa and Sentinelese in particular maintaining steadfast independence and refusing most attempts at contact. In the Nicobar Islands, the indigenous people are the Nicobarese, or Nicobari, living throughout many of the islands, and the Shompen, restricted to the hinterland of Great Nicobar. More than 2,000 people belonging to the Karen tribe live in the Mayabunder tehsil of North Andaman district, almost all of whom are Christians. Despite their tribal origins, the Karen of Andamans have Other Backward Class (OBC) status in the Andamans.
