Tribes of Andaman and Nicobar Islands: Characteristics and Geographical Distribution of Negrito and Nicobarese Communities

India’s only archipelago union territory is home to some of the most isolated human communities left on the planet. Tucked away in the Bay of Bengal, the Andaman and Nicobar Islands host tribes whose ancestors may have walked out of Africa tens of thousands of years ago, and others whose entire way of life was upended by a single morning in 2004. Understanding who these communities are, where they live, and how they have adapted (or resisted adapting) tells us as much about human resilience as it does about the geography of these islands.

A 572-island world at the edge of the bay 🔗

The Andaman and Nicobar Islands consist of 572 islands, islets, and rocky outcrops, though only a small fraction of these are inhabited. The Andaman group in the north is hilly and densely forested, with narrow coastal plains giving way quickly to interior ridges. This rugged terrain has historically kept outsiders at bay and allowed several Negrito tribes to remain isolated for millennia.

Anthropologists classify the indigenous Andamanese as Paleolithic Negrito populations, genetically and culturally linked to the Semang of the Malay Peninsula and the Aeta of the Philippines. These groups share short stature, dark skin, and tightly curled hair, features often associated with some of the earliest human migrations along the southern coastal route out of Africa.

The Negrito tribes of the Andaman Islands 🔗

Four Paleolithic Negrito tribes survive on the Andaman Islands today: the Great Andamanese, the Jarawa (also called Ang), the Onge, and the Sentinelese. Each has followed a strikingly different path over the last two centuries, ranging from near total assimilation to complete voluntary isolation.

Great Andamanese: population decline and rehabilitation 🔗

The Great Andamanese were once the most numerous of the Andaman tribes, with an estimated population of over 2,000 individuals recorded around 1888. Contact with the British penal settlement brought epidemics, alcohol, and violent conflict, and the population collapsed to just a few dozen individuals by the mid-twentieth century. Today, the community numbers under a hundred people, and the ten distinct tribal and linguistic groups that once made up the Great Andamanese have largely merged into a single composite identity.

The survivors have been rehabilitated on Strait Island, where the Andaman and Nicobar Administration has built pucca houses and provided rations, coconut plantations, and medical care. Livelihoods here now revolve around settled activities such as coconut and betel nut cultivation and poultry farming, a sharp departure from the nomadic hunting and gathering economy their ancestors practised for thousands of years. This shift illustrates a recurring pattern across the islands: contact with the outside world tends to move tribes from mobile, forest-based subsistence toward fixed settlements dependent on external support.

Jarawa, Onge and Sentinelese: lifestyle and settlement patterns 🔗

The Jarawa live along the western coasts of Middle and South Andaman and remain a nomadic, hunting-gathering people. Census 2011 figures placed their population at around 380 individuals, a notable recovery from the low numbers recorded a century earlier, largely because the Jarawa avoided the epidemics that devastated the Great Andamanese.

The Onge inhabit Little Andaman, concentrated mainly around Dugong Creek and South Bay. They are semi-nomadic, combining forest gathering with occasional hunting and fishing, and their diet leans heavily on coastal resources such as fish, shellfish, and turtle. Their population has hovered around 100 individuals in recent censuses.

The Sentinelese remain the most isolated tribe in the world, living entirely on North Sentinel Island and actively resisting all outside contact. The 2011 Census placed their population at a contested figure of around 15, though researchers acknowledge the true number could be considerably higher since no reliable headcount has ever been possible. Indian law prohibits travel to the island, and past friendly-contact expeditions were eventually discontinued out of concern for the tribe’s health and autonomy, since they have no immunity to common outside diseases.

Across the Jarawa and related Ang communities, settlement life centres on the chadda, a communal hut structure that can house several families around a shared hearth. Within this system, adolescents move out of their family huts and into separate dormitories once they reach a certain age: boys occupy one dormitory and unmarried girls or widows occupy another, a practice that mirrors youth dormitory traditions found among several tribal societies of mainland India. This arrangement structures both daily labour and courtship, since young people from the dormitories mix during communal hunting, dancing, and foraging activities before eventually marrying and setting up independent family huts within the wider camp.

Crossing to Nicobar: a very different island world 🔗

South of the Ten Degree Channel lies the Nicobar group, comprising twenty-two islands conventionally divided into northern, central, and southern clusters. Car Nicobar, the largest and northernmost island, is relatively flat and low-lying, which has allowed it to support larger, more permanent villages close to the shore. The southern islands, including Great and Little Nicobar, are hillier and more heavily forested, shaping a different pattern of settlement and subsistence.

Great Nicobar’s dense interior forests are home to the Shompen, a small and reclusive hunter-gatherer population genetically distinct from both the Nicobarese and the Andamanese Negrito groups. Genetic studies describe the Shompen as one of the most isolated and poorly understood populations in the archipelago, with very low genetic diversity pointing to a small founding population that has remained largely self-contained for a long time. Unlike the coastal, horticultural Nicobarese, the Shompen depend on forest resources such as wild fruit, tubers, and pandanus, supplemented by limited pig rearing.

Tuhet lineage, Inlom residence and the Kinrooka ceremony 🔗

The Nicobarese, who form the overwhelming majority of the tribal population in the region, speak languages belonging to the Mon-Khmer branch of the Austro-Asiatic family. This classification was first proposed by the anthropologist Whitehead in the early twentieth century, and it has since been supported by genetic research. A recent genomic study led by researchers at the Centre for Cellular and Molecular Biology found that the Nicobarese share ancestral ties with Austro-Asiatic populations of mainland Southeast Asia, though it suggests their ancestors settled in the islands more recently than earlier theories assumed.

Nicobarese social organisation revolves around the tuhet, a patriarchal joint-family lineage unit that collectively owns land, coconut trees, and pigs rather than allowing individual ownership. Each tuhet is headed by a senior male member who represents the family in village council matters alongside elected captains. Marriage practices bring couples under a system of bi-local residence, sometimes described using the term Inlom, where a newly married pair may settle with whichever family group has fewer members at the time, rather than following a strict patrilocal or matrilocal rule.

Death and remembrance are marked through the Kinrooka ceremony, a reburial or secondary funerary rite that allows the community to formally close the mourning period and reaffirm kinship bonds. Rituals of this kind are central to how the Nicobarese maintain continuity across generations, especially in a society where the extended tuhet, rather than the individual, is the primary unit of social and economic life.

When the sea struck back: the 2004 tsunami’s impact on Nicobarese culture 🔗

The earthquake and tsunami of 26 December 2004 caused disproportionate devastation in the Nicobar Islands compared to the Andaman group. Entire villages on islands such as Chowra, Trinket, Little Nicobar, Kondul, and Bampuka were destroyed, and residents were evacuated to temporary shelters that many ended up living in for years longer than planned, as the construction of permanent pucca housing took over seven years to complete.

This prolonged displacement disrupted far more than physical infrastructure. Traditional feasts tied to the coconut and pig-rearing economy became harder to organise once plantations were submerged or destroyed, and communal tuhet living arrangements gave way to smaller, more fragmented nuclear households in the cramped temporary settlements. Cash compensation and a flood of external aid, while well-intentioned, are also documented to have reduced the community’s traditional self-reliance, altering everyday habits and consumption patterns in ways that outlasted the immediate disaster.

Twenty years on, the social effects are still visible. Relocated Nicobarese communities now live in close, sometimes uneasy proximity to non-tribal settlers near their rehabilitation sites, a dynamic that did not exist when villages were spread across their own islands. The tsunami is a stark reminder that natural disasters do not just destroy homes; they can quietly reshape kinship systems, ritual calendars, and cultural continuity for generations.

What do you think? 🔗

What do you think? Given how quickly rehabilitation efforts after the 2004 tsunami altered traditional Nicobarese family structures, how do you think disaster relief policy could better balance urgent humanitarian needs with the preservation of indigenous social systems like the tuhet? And considering the sharply different outcomes for the assimilated Great Andamanese versus the still-isolated Sentinelese, what does this contrast suggest about the risks and benefits of contact for small, vulnerable populations?
