South Asia

India is home to 15 documented ethnic groups in South Asia — led by Hindi Belt Indo-Aryan (~42%), Indian Tribal (~9%), Bengali Indian (~8%), Marathi (~7%). This page blends their phenotype and demographic data into one weighted reference: skin tone, facial features, hair texture and build, drawn from published census and ancestry sources.

Demographic Composition

Composition weights are derived from self-identification in published census and demographic surveys. Each row links to the source ethnic-group atlas page.

Ethnic groupWeightSource
Hindi Belt Indo-AryanHindi Belt Indo-Aryan42.0%Office of the Registrar General & Census Commissioner of India 2011 Census plus Mother Tongue 2011 language data; Hindi-belt Indo-Aryan populations (predominantly Hindi, Urdu, Bhojpuri, Awadhi, Maithili, Magahi, Bundeli, Chhattisgarhi, Haryanvi, Rajasthani-language sub-populations of Uttar Pradesh, Bihar, Madhya Pradesh, Rajasthan, Haryana, Delhi, Uttarakhand, Himachal Pradesh, Jharkhand, Chhattisgarh) comprise approximately 42% of the Indian population, by far the largest umbrella sub-population. The 2011 Census enumerates Mother Tongue rather than ethnicity, and the Hindi-belt Indo-Aryan umbrella aggregates approximately 580+ million speakers across closely-related languages and dialects
Indian TribalIndian Tribal8.7%India 2011 Census, Scheduled Tribes (~104M, ~8.6% of population); the umbrella for India's approximately 700+ Scheduled Tribes (Adivasi / 'original inhabitants') ranging from the demographically substantial Gond, Bhil, Santhal, Mina, Oraon, Munda, Khond, and various Northeastern peoples (Naga, Mizo, Khasi, Garo, Bodo, Kuki, etc.) to the very small Andamanese island peoples (Great Andamanese, Onge, Jarawa, Sentinelese — the Sentinelese are the only contemporary Indian population in voluntary isolation)
Bengali IndianBengali Indian8.0%India 2011 Census, Bengali Mother Tongue speakers (~97M); concentrated in West Bengal, Tripura, parts of Assam (the Barak Valley), and the urban diaspora in major Indian metropolitan areas. Cross-border population shared with Bangladesh
MarathiMarathi6.7%India 2011 Census, Marathi Mother Tongue speakers (~83M); concentrated in Maharashtra plus diaspora communities in major Indian cities

India Phenotype Profile

India's population is among the most internally diverse national populations in the world — approximately 1.4 billion people across approximately 22 Scheduled Languages, ~700 Scheduled Tribes, multiple religious traditions (Hindu ~80%, Muslim ~14%, Christian ~2.3%, Sikh ~1.7%, Buddhist ~0.7%, Jain ~0.4%, plus smaller traditions), and substantial regional, caste-based, and rural-urban variation. The 2011 Census enumerates Mother Tongue rather than ethnicity directly; the composition above approximates ethnic-linguistic distribution from Mother Tongue data. The major Indo-Aryan populations (Hindi-belt ~42%, Bengali ~8%, Marathi ~7%, Gujarati ~5%, Punjabi ~3%, Odia ~3%, Assamese ~1%, plus smaller groups) are concentrated in the northern, western, and eastern regions. The major Dravidian populations (Telugu ~7%, Tamil ~6%, Kannada ~4%, Malayali ~3%) are concentrated in the southern peninsula. The Scheduled Tribes (~9%) are distributed across the central tribal belt, the Northeast, and smaller pockets including the Andaman Islands.

Genome-wide studies (Reich et al. 2009 'Reconstructing Indian Population History', Moorjani et al. 2013, Narasimhan et al. 2019) document Indian populations as showing substantial admixture between two foundational ancestry components — Ancestral North Indian (ANI, related to Steppe-pastoralist populations and broader West Eurasian source populations) and Ancestral South Indian (ASI, related to Andamanese-and-broader-pre-Holocene-South-Asian source populations) — with the ANI/ASI ratio varying systematically by geographic and caste position. Northern, northwestern, and higher-caste populations show higher ANI (~50-70%); southern, eastern, and Scheduled Tribe populations show higher ASI (~60-90%). The Northeast Indian Tibeto-Burman populations carry East Asian ancestry distinct from both ANI and ASI components.

Skin tone across the population spans the full Fitzpatrick range II-VI with IV-V the modal value nationally. The northwestern populations (Punjabi, Kashmiri, northern Hindi-belt, Pashtun-adjacent) skew lighter (II-IV); the southern Dravidian populations (Tamil, Telugu, Malayali, Kannada) skew darker (IV-V); the Northeast Indian Tibeto-Burman populations show distinct East Asian source-population features (Fitzpatrick III-IV with epicanthic-fold variants common); and the Andamanese island peoples show distinct phenotype features related to Southeast Asian / Negrito source populations. Hair texture is predominantly straight to wavy (Andre Walker 1A-2C) across most populations with some curly textures (3A-3B) in southern Dravidian and tribal populations. Hair color is uniformly black to very dark brown across most populations with some medium brown variants in northwestern populations. Eye color is predominantly brown to dark brown nationally, with elevated frequencies of hazel, green, and rarely blue variants in northwestern populations (Kashmiri, Punjabi, northern Hindi-belt). Facial features and build show similar regional patterning. Internal variance is exceptionally high; the country's regional and individual diversity is among the most extensive of any single national population.

A descriptive view, not a claim about individuals

This page shows a weighted aggregate of phenotype observations across the India population, based on demographic composition from published census and ancestry sources. Phenotypes within any country are far more varied than the aggregate suggests; this is a descriptive reference, not a deterministic claim about any individual. For source-level detail on individual ethnic groups, see the constituent atlas pages linked below.

Methodology Notes

Composition weights are derived from the Office of the Registrar General & Census Commissioner of India 2011 Census, the most recent comprehensive Indian census (the planned 2021 census was delayed by the COVID-19 pandemic and political reasons; a 2025-2026 census is in process but has not yet produced public microdata). The 2011 Census enumerates Mother Tongue rather than ethnicity directly — the composition above approximates ethnic-linguistic distribution from Mother Tongue data, supplemented by Scheduled Tribe enumeration. Genome-wide ancestry context (Reich et al. 2009, Moorjani et al. 2013, Narasimhan et al. 2019) supports phenotype interpretation. Caveats: (1) the composition aggregates Indo-Aryan languages of the Hindi belt into a single umbrella that obscures substantial regional and caste-based phenotype variation; (2) the Dravidian languages are enumerated separately but the Tamil-Telugu-Kannada-Malayalam phenotype distinctions are subtle and contested; (3) the 700+ Scheduled Tribes are a single umbrella that aggregates extraordinarily heterogeneous populations across multiple language families and source populations — specific groups should be referenced via dedicated atlas pages where available; (4) the caste-based variation within each language-group umbrella is substantial and is not separately enumerated in the composition; (5) the substantial Indian diaspora globally (~32M+ NRIs and PIOs across the United States, the Gulf states, the United Kingdom, Canada, Australia, the Caribbean, East Africa, Southeast Asia, etc.) is not captured in source-country composition; (6) the Indian-Muslim community is the largest single national Muslim population outside Indonesia and Pakistan but is enumerated by Mother Tongue (most Indian Muslims speak Hindi-Urdu, Bengali, or other regional languages) rather than separately as a religious community in this composition.
