Racial, Linguistic and Ethnic Diversity in India

• Plurality is the defining feature of Indian society. Diversity here is not an exception but the normal condition, built up over thousands of years of migration, interaction and assimilation.
• India’s people differ in ancestry, language, religion, caste, tribe and region. These axes overlap, but they do not coincide, so India cannot be divided into neat blocks.
• The result is often described as unity in diversity: many distinct communities held together by shared cultural practices, economic interdependence and a common constitutional order.

Plurality as the Core of Indian Society

• India has absorbed many outside influences, yet it has never worked as a melting pot, where differences dissolve into one uniform culture.
• It resembles a salad bowl, or a honeycomb:
  • groups keep their distinct identities side by side;
  • together they form a composite civilisation, like the cells of one structure.
• The coexistence rests on tolerance, mutual respect and cultural accommodation: sharing festivals, shrines, foods and markets without merging identities.
• India’s diversity is therefore both social (castes, tribes, religions, languages) and geographical (each group has a home region, a cultural region and a distinct cultural landscape).

Race, Ethnicity and Language

• Race is a biological idea: groups of people distinguished by inherited physical traits (skin colour, hair form, face and skull shape, stature) or, today, by shared genetic ancestry.
• Ethnicity is a socio-cultural idea: a group that sees itself, and is seen by others, as distinct because of a common culture (language, food, dress, customs), shared beliefs, a common history or origin myth, and a strong sense of belonging.
• Language is both a medium of communication and a marker of identity and regional belonging.
• Religion adds a fourth layer of faith-based community.

• These axes are interrelated but distinct.
  • Since people with similar features often lived together, spoke one language and followed one culture, race was wrongly equated with language and culture. “Aryan” and “Dravidian” are language-family names, not races.
  • A Santal, for example, speaks an Austro-Asiatic language, is a Scheduled Tribe by law, may follow Sarna, Hinduism or Christianity, and is genetically a mixture like every other Indian group.

India as a Composite, Multi-layered Society

• Indian civilisation is about 5,000 years old, and its history is one of repeated arrivals. Newcomers came with different aims (trade, conquest, settlement), met the people already here, and each side gave and took.
• Present-day India is a conglomeration of peoples of diverse origin, the product of:
  • successive waves of migration from different parts of the world;
  • continuous interaction between earlier and incoming populations.
• Almost every major human population of Asia has contributed to India, and there is a high degree of biological and cultural admixture.
• Physical features and cultures vary from region to region, reflecting:
  • geographical diversity: the Himalaya, the plains, the plateau, deserts, coasts and islands;
  • the history of settlement and migration along particular routes.

Genesis: Corridors and Refuges

• India’s geography has shaped how its diversity formed.
  • Open frontiers: the north-western passes (Khyber, Bolan), the north-eastern gateway and the sea coasts let newcomers in.
  • Corridor: the Indus–Ganga plain carried each wave eastward and mixed it with earlier settlers. This is why the plains show the most mixing.
  • Refuges: hills, forests and islands (the central tribal belt, the Nilgiri–Western Ghats, the north-eastern hills, the Andamans) sheltered older peoples, languages and faiths. Isolated groups kept their traits while the open corridor was repeatedly remade.
• Major waves, in broad order:
  • The first modern humans arrived along the southern coast more than 50,000 years ago. They are the ancestors of the Ancient Ancestral South Indians (AASI).
  • Iranian-related hunter-gatherer ancestry from the west mixed with them. The two together formed the people of the Indus Valley Civilisation.
  • Steppe pastoralists from Central Asia entered c. 2000–1500 BCE, linked with the spread of Indo-Aryan speech.
  • Austro-Asiatic and Tibeto-Burman speakers came from the east and north-east. The Ahoms entered the Brahmaputra valley in 1228 CE.
  • Persians, Greeks, Shakas, Kushanas and Hunas came through the north-west in ancient times; Turks, Afghans and Mughals in the medieval period.
  • Arabs, Jews, Syrian Christians and Parsis came by sea to the western coast; the Portuguese reached Calicut in 1498, followed by the Dutch, French and British.
• Each encounter led to:
  • cultural exchange (diffusion);
  • assimilation and adaptation, often by absorbing newcomers as new jatis into the caste order;
  • enrichment of a composite civilisation, so diversity is integrated and cumulative, not fragmented.
• The Aryan–Dravidian contrast is the earliest ethnic differentiation in the record:
  • Older histories placed Aryans in the Indus region about 2500 BCE. The evidence now dates the spread of Indo-Aryan speech to the second millennium BCE.
  • The two were told apart by complexion (fair against dark) and by speech.
  • Anthropologists linked Aryans with Caucasoid and Dravidians with Proto-Australoid elements.
  • Aryan speakers spread across the north and Dravidian speakers became concentrated in the south, an early regional contrast that mixing later blurred. Most accounts hold that Dravidian speech was in India first.

Geographical Bases of Diversity

• Relief and isolation:
  • Mountains, plateaus, forests and islands separated communities and slowed contact.
  • Each pocket developed its own dialect, customs and gene pool: the Nilgiri groups, the Bastar tribes and the Andaman islanders are examples.
• Climate and livelihood:
  • Contrasting environments produced contrasting ways of life: pastoralism in the Thar and the high Himalaya, wet-rice farming in the deltas, shifting cultivation in the north-eastern hills, fishing on the coasts.
  • Food, dress, house types and festivals follow these livelihoods.
  • Diversity also shows in forms of rural and urban settlement, land tenure, farming practice, kinship, marriage rites and inheritance.
• Accessibility:
  • Open plains and coasts received many waves and became mixing zones.
  • Remote areas kept older layers, so diversity is greatest at the margins of each culture area.
• Size:
  • A subcontinent of 3.29 million km², spanning about 30 degrees of latitude and longitude, could hold many culture regions at once.
• Political history:
  • Changing kingdoms, empires and colonial rule redrew boundaries and moved people: soldiers, traders, artisans, plantation and mine labour.
  • Each move left pockets of migrants far from home: Marathas in Thanjavur, Tamil traders in Mumbai, Santals in Assam’s tea gardens.

Continuity and Change

• Indian society has changed in its demographic composition, material culture, values and norms and patterns of behaviour, yet it has kept a continuous civilisational identity.
  • Change is constant; its pace varies (slow in traditional societies, rapid under modern conditions).
  • Modern forces cut both ways. Urbanisation, schooling, media and migration spread common languages and tastes, yet they also make groups more aware of their distinct identity, which they assert through movements for language, autonomy or recognition.
  • Today tradition and modernity coexist: caste and kinship persist, while equality, democracy and globalisation reshape them. This blend of continuity and change runs through the whole historical perspective of Indian society, from the Indus cities to the present.

Racial Diversity

• Biologically, all humans belong to one species, Homo sapiens. Populations differ in the frequency of visible traits: hair colour and texture, skin and eye colour, eyelid, nose, lip and skull shape, and stature.
• It is a fallacy to link race with intellect, culture or social worth.
  • Cultural traits are learned, not inherited.
  • No group is superior or inferior, and “pure races” do not exist, least of all in a land of long migration.
  • Racial and linguistic boundaries may once have coincided, but language is learned, not biologically transmitted.
  • Intermarriage (miscegenation) has gone so far that pure types are theoretical constructs, which also makes racial origins hard to fix.
• Fossil evidence from prehistory is scant, so the first ethnic stocks remain unknown. Accounts of the Indus Valley Civilisation already show people of mixed origins and diverse types, so this variety is ancient.
• Classical classifications were attempts of the colonial and early national period. They are now historical:
  • Herbert Hope Risley, Census Commissioner for the 1901 Census, identified seven types: Turko-Iranian, Indo-Aryan, Scytho-Dravidian, Aryo-Dravidian, Mongolo-Dravidian, Mongoloid and Dravidian. Critics noted that he mixed language labels with racial ones.
  • Egon von Eickstedt (1934) placed a dark-skinned Melanid element among the oldest layers of the south, sometimes described as a Proto-Negroid population present before other stocks arrived.
  • B. S. Guha, using the 1931 Census survey, recognised six main races with nine subtypes. The exact size of each group cannot be determined. It is still the most cited scheme and is valuable mainly as evidence of India’s composite population:
    • Negrito: traces in the Andamans and among some hill tribes of the south;
    • Proto-Australoid: the tribes of the central belt (Santal, Munda, Oraon, Bhil);
    • Mongoloid: the Himalaya and the north-east;
    • Mediterranean: the Dravidian-speaking south and much of the north;
    • Western Brachycephals: Gujarat, Kathiawar, Coorg and Bengal, and the Parsis;
    • Nordic: the north-west, mixed with other elements.
• Genomic evidence has replaced these typologies:
  • Almost every Indian group is a mixture of two ancestral populations, the Ancestral North Indians (ANI) and Ancestral South Indians (ASI) (David Reich and colleagues, 2009).
  • These themselves formed from AASI, Iranian-related and Steppe ancestry after the Indus period (Vagheesh Narasimhan and colleagues, 2019).
  • The Rakhigarhi genome (2019) showed that Harappans had no Steppe ancestry.
  • Endogamy over about 2,000 years then gave each caste and tribe a distinct genetic profile.
• Independent India’s census does not record race, and the old racial groups of India survive only as historical classifications.
• Nature of racial diversity in India:
  • continuity of migration and assimilation;
  • a high degree of mixing, so there are no pure or isolated races;
  • many traits coexist within the same population, and race has little power to explain social reality.

Linguistic Diversity

• India is a polyglot country: many languages and dialects coexist, the product of long regional isolation followed by integration.
  • In the past, poor transport kept communities confined to small areas, so speech forms diverged locally into many dialects, some spoken within a radius of only 7–8 km. That isolation is why India has about 1,572 languages and dialects each spoken by fewer than 1,00,000 people, besides the 22 scheduled languages.
• Census 2011 gives the scale:
  • 19,569 raw names were returned for mother tongue.
  • These were rationalised to 1,369 mother tongues and grouped into 121 languages with 10,000 or more speakers.
  • 22 languages are in the Eighth Schedule; they are the mother tongue of 96.71% of Indians.

• Four main language families:
  • Indo-Aryan (78.05% of speakers): north, west, east and centre.
  • Dravidian (19.64%): the south, with Gondi and Kurukh in central India.
  • Austro-Asiatic (1.11%): the Munda languages of Chotanagpur and Khasi.
  • Tibeto-Burmese (1.01%): the Himalaya and the north-east.
  • Smaller groups: Andamanese, Semitic (Arabic) and Iranian (Pashto).
• Hindi is the largest mother tongue:
  • 43.63% in 2011, up from 36.99% in 1971.
  • The 1991 Census table gave 39.85%, rising to 44.98% with Urdu, which shares Hindi’s grammar but not its script.
  • It includes many grouped mother tongues such as Bhojpuri and Rajasthani.
  • Many more speak it as a second or third language, so it serves as a link language. English plays the same role in higher education, administration and business.
• Multilingualism is the everyday reality:
  • about 26% of Indians reported a second language and about 7% a third (Census 2011);
  • migrants often switch to the dominant regional language.
  • Older census tables recorded only mother tongue, which understated how many people actually speak a language.
• No State is monolingual, even after the linguistic reorganisation of States in 1956. Each State holds several linguistic communities, and Hindi is among the top three languages in most.
• Diversity of scripts matches the diversity of speech: Devanagari, Bengali–Assamese, Gurmukhi, Gujarati, Odia, Tamil, Telugu, Kannada and Malayalam scripts, Perso-Arabic for Urdu and Kashmiri, Ol Chiki for Santali, Meitei Mayek for Manipuri, and the Roman script for many north-eastern languages.
• Each major language has its own literary heritage. Indian writers in English have a global readership.
• Language has been a strong force in regional identity politics:
  • movements for Andhra (1953), Samyukta Maharashtra and Maha Gujarat (1960) and a Punjabi-speaking Punjab (1966) redrew the map;
  • Tamil Nadu’s agitation against Hindi in 1965 led to the continued use of English alongside Hindi;
  • boundary disputes such as Belagavi between Karnataka and Maharashtra are still alive.
• Small languages are under pressure. UNESCO’s atlas lists about 197 Indian languages as endangered, mostly tribal tongues of the north-east and central India.
• India’s linguistic structure therefore combines:
  • micro-level diversity (thousands of speech forms);
  • macro-level integration (link languages);
  • functional multilingualism: people use different languages for home, market, school and office.
  • cultural embeddedness: language carries identity, tradition and social relations;
  • porous boundaries: State reorganisation gave an administrative frame, but linguistic communities keep moving and mixing.

How the Racial and Linguistic Maps Relate

• Genes, languages and cultures travel together only partly:
  • Austro-Asiatic speakers (Munda, Khasi) carry extra East and South-east Asian ancestry, matching the eastern origin of their languages.
  • Tibeto-Burman speakers of the Himalaya and the north-east also carry East Asian ancestry.
  • Dravidian speakers in the south tend to have more ASI ancestry, and Indo-Aryan speakers in the north-west more ANI ancestry.
• The match is loose:
  • many tribes speak Indo-Aryan languages (Bhili is the largest non-scheduled language);
  • the Brahui of Balochistan speak a Dravidian language far from the south;
  • groups have switched languages many times through contact and conquest.
• Language, ancestry and culture are therefore separate maps that only partly overlap. This is the strongest argument against the old practice of naming races after languages.

Ethnic Diversity

Nature and Sources

• India is an exceptionally diverse ethnic landscape. Its variety of ecological niches (mountains, plains, plateaus, coasts, forests) allowed:
  • distinct communities to evolve and survive;
  • continuous exchange among them;
  • processes of assimilation, acculturation and harmonisation.
• Ethnic identity in India draws on several overlapping sources:
  • ancestry and region of origin;
  • religion;
  • caste and sub-caste (jati);
  • language and dialect;
  • tribe.
• These intersect to form a multi-layered identity system, not rigid ethnic boundaries.
• Waves of newcomers (Indo-Aryans, Scythians, Kushanas, Turks, Mughals, Europeans) left a rich mix of genes and cultures.

The Scale of Diversity

• The People of India project of the Anthropological Survey of India studied 4,635 communities in all States. It found that they used 325 languages in 25 scripts, and that a large share of Indians are migrants, living away from their place of origin.
  • Its register (1996) holds 17,096 entries of castes, communities, sub-groups, surnames and other names: 8,530 castes or communities, 3,123 sub-groups and 2,729 surnames.
• Census 2011 lists 705 individual ethnic groups as Scheduled Tribes and 1,241 as Scheduled Castes. Each has its own spatial pattern: the major tribes of India, from the Bhil and Gond to the Santal and Naga, live mostly in hill and forest belts, while Scheduled Castes are spread through the plains.
• Religion adds another layer:
  • Hindus 79.8%, Muslims 14.2%, Christians 2.3%, Sikhs 1.7%, Buddhists 0.7%, Jains 0.4% (Census 2011);
  • all of these except Hindus, together with the Parsis, are the six notified religious minorities;
  • their spatial pattern is one of concentration in frontier, coastal and hill States around a Hindu-majority core.
• Mother-tongue returns keep rising: about 1,652 names in 1961, around 3,000 in 1971, around 10,000 in 1991 and 19,569 raw returns in 2011. Better enumeration is part of the reason; growing identity consciousness and the assertion of local identities are another. Ethnic identity is dynamic and self-asserting, not fixed.
• Ethnicity and territory: many groups seek a homeland or self-rule.
  • Jharkhand (2000) and Chhattisgarh (2000) were carved out of areas with a large tribal share. Scheduled Tribes were 26.2% and 30.6% of the two States in 2011, not majorities.
  • Bodoland Territorial Region came out of the Bodo Accord of 2020.
  • The Gorkhaland demand in the Darjeeling hills continues.
  • Autonomous councils serve the Karbi, Dimasa, Garo, Khasi and other groups.
• Ethnicity and the city: migration brings groups together in cities, but it also produces ethnic neighbourhoods, such as Tamil areas of Mumbai, Bengali colonies in Delhi and north-eastern clusters in Delhi and Bengaluru. Enclaves give support networks, but they can also harden social distance.

Caste and Tribe as Ethnic Units

• The jati is the working unit of Indian society. It is endogamous, usually tied to a traditional occupation, and ranked locally.
  • Thousands of jatis exist, and each region has its own set. A caste name in Tamil Nadu has no exact match in Punjab.
  • Endogamy keeps jatis distinct over centuries. This is visible even in their genes.
• Tribes differ: they are territorial communities with their own dialect, customary law and close ties to land and forest.
  • Many tribes have moved towards caste society over time. Some became castes, others kept a separate identity.
• Caste and tribe make Indian ethnicity local and hierarchical, not only regional.

Ethnic Regions of India

Ethnic Diversity of North-east India

• The north-east is India’s most ethnically varied region.
  • Tibeto-Burman peoples dominate the hills: Naga, Mizo, Garo, Bodo, Tripuri, the Adi and Nyishi of Arunachal.
  • The Khasi speak an Austro-Asiatic language.
  • Assamese and Bengali speakers dominate the valleys.
  • Nepali, Bengali and the “tea tribes” (Santal, Munda and Oraon brought to the Assam tea gardens) are later migrants.
• The hill–valley divide is the key spatial pattern:
  • Meitei in the Imphal valley; Naga and Kuki-Zo in the hills of Manipur;
  • Assamese and Bengali speakers on the Brahmaputra and Barak plains; tribes in the surrounding hills.
• Scheduled Tribes are a large share of the population (Census 2011): Mizoram 94.4%, Nagaland 86.5%, Meghalaya 86.1%, Arunachal 68.8%, Tripura 31.8% and Assam 12.4%.
• Ethnic disparities within the region are wide:
  • literacy ranges from 91.3% in Mizoram to 65.4% in Arunachal Pradesh;
  • valley towns hold most jobs, colleges and markets; the hills depend on government employment and shifting or terrace farming;
  • within Assam, the Brahmaputra and Barak valleys, the Bodo areas and the Karbi and Dima Hasao hills differ sharply in language, religion and access to services;
  • roads, railways and industry reached the region late, and the narrow Siliguri corridor remains its only land link with the rest of India.
• Tensions recur over land, migration, jobs and autonomy: demands for new States and autonomous councils, the debate over migration into Assam, and the ethnic violence in Manipur since May 2023.
• The Sixth Schedule gives autonomous councils to the tribal areas of Assam, Meghalaya, Tripura and Mizoram.

Forces of Division

• Indian society has repeatedly been pulled along lines of religion, caste, language and region. The Partition of 1947, drawn on religious identity, is the gravest example.
• Two processes turn difference into conflict:
  • Essentialism (primordialism): communities are assumed to be inherently separate, with unconnected histories.
  • Instrumentalism: identities are mobilised for political power and votes.
• Both try to convert organic coexistence into conflicting identities.

Syncretism: The Lived Reality

• In everyday life Indian society works as a honeycomb: communities live in close proximity and exchange culture constantly.
• Evidence of syncretism:
  • Overlapping identities in some communities and families, such as Hindu–Sikh, Hindu–Muslim and Hindu–Buddhist.
  • Pre-conversion practices continue after conversion; religion is often laid over a shared regional culture.
  • Tribal communities practise multi-religious customs. The Nicobarese, for example, blend Christianity with older beliefs, and segments of the Nicobarese and the Khasi Muslims of Meghalaya profess three or four faiths (Hinduism, Islam, Christianity and tribal religions).
  • Every religious and tribal community also has its own sub-sects and groups.
• The Bhakti and Sufi movements stressed devotion, equality and human unity, challenged rigid caste and religious boundaries, and created shared sacred spaces:
  • Sufi shrines such as Ajmer draw Hindu and Muslim pilgrims alike;
  • Shirdi Sai Baba is revered by both Hindus and Muslims;
  • tradition credits the Sufi saint Mian Mir of Lahore with laying the foundation stone of the Harmandir Sahib at Amritsar;
  • Konkani Muslim weddings use a tied amulet or mangalsutra, the tali of Hindu custom;
  • Munshi Premchand’s telling of Syed Salar Masud Ghazi, who left his own wedding at a woman’s cry to save cows, belongs to the same tradition;
  • the legend of Bibi Nachiyar, a Muslim devotee of Vishnu, is honoured in Vaishnava temple tradition, as at the Cheluvanarayana temple.
• Shared creations of many communities: Urdu, born of contact between Persian and the speech of the Delhi region; Hindustani music, carried by Hindu and Muslim lineages of musicians; and Indo-Islamic architecture, from Fatehpur Sikri to the Deccan.
• Historical fluidity of identities: the word “Hindu” first had a geographical meaning, for the people beyond the Indus (Sindhu). In that usage even Muslims and Christians were called Hindus. Identities were once more territorial and cultural than strictly religious.

Diversity: Asset and Challenge

• As an asset:
  • a vast store of knowledge, crafts, cuisines and arts;
  • a large domestic market with regional specialisations;
  • soft power through languages, faiths, films and the diaspora;
  • resilience: many centres of culture, not one.
• As a challenge:
  • regionalism and sons-of-the-soil movements against migrants (Assam, Maharashtra, the north-east);
  • inter-State disputes over borders and water, often tied to language;
  • communal and ethnic conflict, which reshapes settlement through segregation and displacement;
  • uneven development, where one group feels left behind;
  • administrative cost of many languages and special arrangements.

Bonds of Unity

• Geographical unity: a subcontinent framed by the Himalaya and the seas, with one monsoon rhythm shaping farming and festivals.
• Pilgrimage circuits link distant regions: the four dhams at the corners of the country, the Shakti peethas, the Kumbh sites, and Sufi and Sikh shrines.
• Shared cultural stock: the epics, classical music and dance forms, and harvest festivals held at the same season under different names.
• Economic interdependence: a national market and internal migration that mixes people in every large city.
• Political institutions: a common Constitution, universal franchise, a federal structure that gives regions a voice, and national services.
• Historical unification: rulers such as Ashoka, Samudragupta and Akbar brought large parts of the subcontinent under one power, though only British rule made India a single political entity.
• Caste as a common idiom: caste is found among Hindus, Muslims, Christians, Jews, Sikhs, Buddhists and Jains, so it cuts across faiths even as it divides.

Constitutional Recognition and the Indian Model

• The Constitution institutionalises diversity through:
  • secularism;
  • minority rights (Articles 29 and 30);
  • recognition of languages (the Eighth Schedule);
  • protective provisions for Scheduled Castes and Scheduled Tribes.
• Region-specific safeguards add to these: the Fifth and Sixth Schedules for tribal areas, and Article 371 provisions, such as 371A for Nagaland and 371G for Mizoram, which protect customary law and land.
• Unity in diversity is thus constitutional and political, not only cultural.
• India and the West compared:

• Nature of Indian diversity, in sum:
  • multiplicity of identities (race, ethnicity, language, religion, caste);
  • overlap and interdependence among them;
  • historical continuity combined with change;
  • integration through shared practices and values.
• The geographical process behind it is migration → interaction → assimilation → cultural synthesis.
• In the changed setting of the twenty-first century, few isolated groups remain as typical representatives of a race or ethnic group. Dividing people by race, ethnicity or caste feeds sub-nationalism.
• Keeping this balance today means balancing identity assertion with pluralism and secularism.
