Tribal Ethnography: Geographical Distribution of Tribes Across India’s Five Regions

Walk from the icy ridges of Arunachal Pradesh to the coral-fringed islands of the Andamans, and you will pass through dozens of tribal worlds, each with its own language, deity, and way of reading the forest. India is home to over 700 officially recognised tribal communities, and making sense of where they live has kept anthropologists busy for nearly a century. The most widely taught answer comes from anthropologist L.P. Vidyarthi, who grouped this vast diversity into five geographical zones based on administrative, ecological, and socio-economic patterns. Understanding this map is the first step to understanding tribal India itself.

Why anthropologists needed a map at all 🔗

Tribal communities in India were never scattered at random. Their locations followed rivers, forests, hill ranges, and old migration routes, which is why zonal classification became a core tool in tribal studies. Early scholars like B.S. Guha worked with a simpler three-zone model, while D.N. Majumdar, T.N. Madan, and S.C. Dube refined it further by adding a separate western belt. Building on this body of work, Vidyarthi proposed a five-fold classification that remains the standard reference today: the Himalayan region, Middle India, Western India, South India, and the Islands. Each zone reflects a distinct ecological setting, and each has produced its own cluster of tribal cultures.

The Himalayan region and its three sub-belts 🔗

The Himalayan zone runs along India’s northern rim and is usually split into three sub-regions, since the terrain, language families, and tribal histories change dramatically from east to west.

The north-eastern Himalayan sub-region 🔗

This belt covers the north-eastern states along the borders with China, Myanmar, Bhutan, and Nepal. It has the country’s highest concentration of tribal communities relative to population, with groups such as the Khasi, Garo, Rabha, and Naga forming the social backbone of Meghalaya and Nagaland. Further north, the Dafla (Nyishi), Abor (Adi), and Apatani occupy the river valleys of Arunachal Pradesh, while smaller groups such as the Aka, Gurung, and Mishmi live in the high ranges between the Dibang and Lohit rivers, as documented in a tribal distribution unit prepared for anthropology students. The isolation of this terrain has allowed an unusually large number of distinct languages and dialects to survive side by side.

The central and north-western Himalayan sub-regions 🔗

Moving west, the central Himalayan belt takes in the Tarai lowlands of Uttar Pradesh and parts of Sikkim and north Bengal, home to the Tharu, Kachari, Toto, and Lepcha communities. The north-western Himalayan sub-region stretches through Himachal Pradesh and Jammu and Kashmir, where pastoral and semi-pastoral tribes such as the Gaddi and Gujjar move with their herds between summer and winter pastures. Across this entire Himalayan zone, ecology dictates lifestyle almost as much as ethnicity does – hill cultivation, shifting agriculture, and pastoralism remain the dominant occupations.

Middle India and Western India: the country’s tribal heartland 🔗

If the Himalayan belt is defined by isolation, Middle India is defined by sheer scale. This is where the largest share of India’s tribal population actually lives.

Middle India’s tribal belt 🔗

Stretching across Bihar, West Bengal, Odisha, Madhya Pradesh, and parts of Andhra Pradesh and Telangana, this zone is sometimes called the tribal heartland of India, accounting for more than half the country’s tribal population according to regional distribution data compiled for sociology students. It is home to some of India’s most populous tribes: the Santal, Oraon, Munda, and Ho in the Chotanagpur plateau; the Gond, whose presence stretches from Madhya Pradesh’s Bastar region into the Adilabad district of Telangana; and the Saora, Kharia, and Baiga spread through Odisha’s forested uplands. Many of these groups share a documented history of resistance to colonial-era land and forest policies, a thread that continues to shape tribal politics in these states today.

Western India’s tribal belt 🔗

South-west of Middle India lies a second dense tribal corridor covering Rajasthan, Gujarat, Maharashtra, and Goa. Its signature community is the Bhil, whose homeland spans the Vindhya and Satpura ranges across all four states, alongside the Mina (concentrated in eastern Rajasthan), the Saharia, the Koli, and the Varli of coastal Maharashtra and Goa. This belt is drier and less forested than Middle India, and its tribal economies historically leaned more on pastoralism and dryland farming than on forest gathering alone.

Southern India and the island tribes 🔗

The southern tip of the country and its offshore territories form the fourth and fifth zones – smaller in population share but disproportionately important to anthropology, because they include some of the most ancient and isolated human groups on Earth.

Tribes of the southern peninsula 🔗

South of the Krishna river, in Tamil Nadu, Kerala, and Karnataka, tribal life is closely tied to the Western and Eastern Ghats. The Chenchu and Yerukala are traditionally forest-dwelling and semi-nomadic groups, while the Toda and Kota of the Nilgiri hills are known for their distinctive pastoral and craft traditions. The Kadar of Kerala’s forests and the Kurumba and Irula of the Nilgiri-Coimbatore region round out this zone. Most southern tribes speak Dravidian languages and have developed detailed traditional knowledge of forest ecology and herbal medicine, passed down largely through oral tradition.

The island region: isolation as a way of life 🔗

The Andaman and Nicobar Islands hold India’s smallest but most anthropologically significant tribal population. Groups such as the Great Andamanese, Onge, Jarawa, and Car Nicobarese have lived on these islands for tens of thousands of years, largely cut off from mainland contact. The most extreme case is the North Sentinelese, who inhabit North Sentinel Island and continue to resist all outside contact, a stance the Indian government protects by law, as Survival International documents in its work on uncontacted peoples. Several of these Andaman groups are officially recognised as Particularly Vulnerable Tribal Groups because their numbers have fallen so low; a 2013 government reply in the Lok Sabha put the population of the Great Andamanese, Onge, Sentinelese, Shompen, and Jarawa at under 500 each.

What the Census 2011 numbers reveal 🔗

Numbers bring this geography into sharper focus. According to the 2011 Census report on Scheduled Tribes, India’s tribal population stood at 10.42 crore, or 8.6 per cent of the total population, with 705 ethnic groups officially notified as Scheduled Tribes. The distribution across states is highly uneven. Consistent with Middle India’s outsized share of the tribal population, state-wise census analysis shows Madhya Pradesh holding the largest share at 14.7 per cent of India’s ST population, followed by Maharashtra at 10.1 per cent and Odisha at 9.2 per cent. At the other end of the scale, five states and union territories – Punjab, Haryana, Chandigarh, Delhi, and Puducherry – have no notified Scheduled Tribes at all, largely because none of their territory has been declared a Scheduled Area under the Fifth or Sixth Schedule of the Constitution.

The same census data illustrates just how uneven tribal population sizes can be. On one end sit giants like the Bhil, Gond, and Santhal, together accounting for a large share of India’s entire tribal population and spread across multiple states. On the other end sits the Sentinelese, whose entire recorded population in the 2011 enumeration was just 15 people – a figure gathered from a boat offshore rather than a conventional door-to-door count, reflecting how differently tribal India’s smallest and largest communities must be studied and served. The Ministry of Tribal Affairs continues to track this range of communities, from millions-strong groups to some of the most vulnerable populations on the planet, through separate statistical profiles and welfare schemes tailored to each.

What do you think? Does grouping such different communities – from millions-strong tribes like the Bhil to a handful of Sentinelese islanders – under one umbrella term like “Scheduled Tribe” help or oversimplify how India understands tribal diversity? And what do you think explains why some regions, like Middle India, became home to such a dense concentration of tribal populations while others did not?
