Demographic Profile and the Traditional Indian Social System — UPSC Anthropology Optional Notes

1. Concepts and Definitions

Demography: the scientific study of the size, composition and distribution of a population and of how these change through births (fertility), deaths (mortality) and movement (migration); the term was coined by Achille Guillard in 1855.

Population structure: the make-up of a population by age, sex, residence (rural or urban), religion, caste and tribe, language, literacy and occupation.

Population growth: natural increase (births minus deaths) plus net migration; in India growth is almost wholly natural increase.

Total Fertility Rate (TFR): the average number of children a woman would bear in her lifetime at current age-specific rates; 2.1 is the replacement level.

Sex ratio: in India it is expressed as females per 1,000 males; the child sex ratio refers to the 0 to 6 age group.

Demographic transition: the shift from high birth and death rates to low birth and death rates, described by Warren Thompson (1929) and Frank Notestein (1945).

Demographic dividend: the growth opportunity that opens when the working-age population (15 to 64) is large relative to dependent children and elderly.

2. India's Population: Key Figures with Year

Size (Census 2011): 121.09 crore people, about 17.5% of the world's population on 2.4% of its land area.

Growth: decadal growth in 2001 to 2011 was 17.7%, the lowest since independence, down from 21.5% in 1991 to 2001.

Sex ratio (Census 2011): 943; the child sex ratio was 919, the lowest recorded, showing son preference and sex-selective abortion.

Literacy and settlement (Census 2011): literacy 74.04% (males 82.14%, females 65.46%); density 382 persons per sq km; 68.8% rural and 31.2% urban.

Social composition (Census 2011): Scheduled Castes 16.6% (20.14 crore) and Scheduled Tribes 8.6% (10.43 crore).

Religion (Census 2011): Hindus 79.8%, Muslims 14.2%, Christians 2.3%, Sikhs 1.7%, Buddhists 0.7%, Jains 0.4%, others about 0.7%.

Most populous country: by the UN's World Population Prospects estimates, India overtook China as the world's most populous country in 2023.

Fertility (SRS Statistical Report 2023, released September 2025): TFR fell to 1.9, below replacement; Bihar was highest (2.8) and Delhi lowest (1.2); crude birth rate 18.4 and crude death rate 6.4 per 1,000.

NFHS-5 (2019 to 2021): TFR 2.0; 23.3% of women aged 20 to 24 had married before the age of 18.

Census 2027: the first census since 2011, because the 2021 round was postponed due to COVID-19; houselisting ran from April to September 2026 and population enumeration has the reference date 1 March 2027 (1 October 2026 for snow-bound areas).

It is India's first digital census and will record caste for all communities, following the decision of the Cabinet Committee on Political Affairs on 30 April 2025; the last full caste count was in 1931.

3. Phases of Population Growth

1901 to 1921, stagnant population: famines, plague and the 1918 influenza kept numbers flat; the 1921 Census shows a fall, so 1921 is called the year of the great divide.

1921 to 1951, steady growth: mortality began to fall with famine relief, better transport and disease control.

1951 to 1981, rapid growth (population explosion): death rates fell sharply while birth rates stayed high, so decadal growth stayed above 21%.

1981 to 2011, high growth with clear signs of slowing: fertility began to fall, fastest in the southern states.

4. Factors Influencing Structure and Growth

Mortality decline: Kingsley Davis (The Population of India and Pakistan, 1951) showed that growth after 1921 came mainly from falling deaths, not rising births.

Early and universal marriage: marriage is near-universal among Hindu, Muslim and tribal communities, which lengthens the reproductive span.

Son preference: patrilineal descent, patrilocal residence, dowry and the son's ritual role (performing the last rites and repaying the pitri rina) make couples continue childbearing until sons are born and distort the sex ratio.

Child survival: high infant mortality encourages more births as insurance; SRS 2022 put the infant mortality rate at 26 per 1,000 live births.

Education and status of women: female literacy and age at marriage are the strongest predictors of lower fertility, as the contrast between Kerala and Bihar shows.

Economic value of children: in agrarian and tribal households children work in the fields, herd animals and collect forest produce.

Religion and region: fertility differences between religions narrow when education and income are held constant; region (north versus south) matters more.

Migration: rural-to-urban and inter-state migration (from Bihar, Uttar Pradesh, Odisha and Jharkhand to Maharashtra, Gujarat, Delhi and Kerala) changes the sex ratio and age structure of both source and destination areas.

Policy: India started the world's first national family planning programme in 1952; the National Population Policy 2000 aimed at replacement fertility, and the 84th Amendment (2001) froze the delimitation of seats until the first census after 2026.

5. Theory and Debates

Thomas Malthus (1798): population grows geometrically and food arithmetically, so famine, disease and moral restraint act as checks.

Ester Boserup (The Conditions of Agricultural Growth, 1965): population pressure stimulates agricultural intensification, the reverse of the Malthusian view.

Mahmood Mamdani (The Myth of Population Control, 1972): his restudy of the Khanna family-planning trial in Punjab argued that poor families had many children because children were economic assets, not out of ignorance.

John Caldwell (wealth-flows theory): high fertility is rational where wealth flows upward from children to parents; fertility falls when the flow reverses, through schooling and the nuclear family.

Anthropological view: fertility, age at marriage and family size are embedded in kinship, religion and gender norms, so purely medical or coercive programmes, such as the sterilisation drive of 1975 to 1977, failed and provoked resistance.

Tribal demography: the ST sex ratio was 990 in Census 2011 (child sex ratio 957), better than the national figure, reflecting women's economic role and bride price; but some PVTGs such as the Great Andamanese and Onge have very small or declining numbers.

Ageing: the share of people aged 60 and above was 8.6% in Census 2011; UNFPA's India Ageing Report 2023 projects it to exceed 20% by 2050, so the demographic dividend is time-bound.

6. Diagrams to Draw

Population pyramid: draw a vertical axis of five-year age groups (0 to 4 at the bottom up to 80 and above at the top) and a horizontal axis of percentage, with males on the left and females on the right.

Draw India 2011 as a broad-based pyramid narrowing upward, and beside it a projected shape for the 2030s that is barrel-like (narrower base, bulge between 20 and 50); label them expansive and constrictive.

Demographic transition model: x-axis time, y-axis rates per 1,000; draw a birth-rate line and a death-rate line, shade the gap as natural increase, and mark Stage 1 (both high), Stage 2 (death rate falls), Stage 3 (birth rate falls) and Stage 4 (both low); place India in late Stage 3.

7. Using It in the Exam

10 marks (150 words): define the demographic profile, give four Census 2011 figures and the latest SRS fertility figure, and end with one line on the demographic dividend.

15 marks (200 words): add the factors (biological, socio-cultural, economic and policy) with one Indian example each, and draw the population pyramid.

20 marks (250 words): structure the answer as phases of growth, factors, regional and tribal variation, theory (Malthus, Boserup, Mamdani, Caldwell) and the way forward, including Census 2027.

Keywords: demographic transition, TFR, sex ratio, son preference, demographic dividend, regional divergence.

Quotable: Mamdani's argument, paraphrased, is that people are not poor because they have large families; they have large families because they are poor.

1. Concepts and Definitions

Racial element: a population type defined in older anthropology by shared physical traits such as skin colour, stature, head form (cephalic index) and nose form (nasal index); biologists now reject races as discrete types and speak of populations and ancestry.

Ethnic group: people who share a culture, language and belief in common descent; Fredrik Barth (Ethnic Groups and Boundaries, 1969) stressed that the boundary maintained between groups matters more than the cultural content inside.

Language family: a group of languages that descend from a common ancestral language, shown by regular sound correspondences and shared basic vocabulary.

Mother tongue (Census definition): the language spoken in childhood by the person's mother; if the mother died in infancy, the language mainly spoken in the household.

2. Racial Classifications of the Indian Population

H.H. Risley (Census of 1901; The People of India, 1908): seven types based mainly on anthropometry, especially the nasal index.

Risley's types: Turko-Iranian (Baluchistan, North-West Frontier), Indo-Aryan (Punjab, Rajputana, Kashmir), Scytho-Dravidian (western India, for example Marathas and Coorgs), Aryo-Dravidian (Uttar Pradesh, Bihar), Mongolo-Dravidian (Bengal, Odisha), Mongoloid (Himalaya, Assam) and Dravidian (south and central India).

Risley linked race to caste, arguing that caste status rose as the nose became finer; G.S. Ghurye (Caste and Race in India, 1932) accepted a partial race-caste link only for northern India and rejected it elsewhere.

B.S. Guha (based on measurements from the 1931 Census operations; Racial Elements in the Population, 1944): six main races with nine sub-types, the most widely cited scheme in UPSC answers.

Negrito: short stature, dark skin, frizzy hair; Onge, Jarawa, Great Andamanese and Sentinelese of the Andaman Islands; Guha's claim of Negrito traits among the Kadar and Irula of the south is debated.

Proto-Australoid: dark skin, wavy hair, broad flat nose, long head; most tribes of central and southern India such as the Munda, Santal, Ho, Oraon, Bhil and Chenchu.

Mongoloid: Palaeo-Mongoloid, long-headed (sub-Himalayan and Assam hill tribes such as the Nagas) and broad-headed (Chittagong Hill Tracts, for example Chakma), and Tibeto-Mongoloid (Sikkim and Bhutan, for example the Bhutia).

Mediterranean: Palaeo-Mediterranean (Dravidian-speaking peoples of the south), Mediterranean proper (Punjab, Gangetic plain) and the Oriental type (Punjab, Rajasthan).

Western brachycephals: Alpinoid (Gujarat, Bengal), Dinaric (Bengal, Odisha, Coorg) and Armenoid (the Parsis of Bombay).

Nordic: tall, fair, long-headed; found in the north-west, Punjab and Rajputana.

Other schemes: A.C. Haddon and Egon von Eickstedt offered their own classifications, and D.N. Majumdar added blood-group (serological) data to measurements; all such typologies are now treated as historical.

3. The Genetic Picture

Reich et al. (Nature, 2009): most Indian groups descend from two ancestral populations, Ancestral North Indians (ANI, related to West Eurasians) and Ancestral South Indians (ASI, distinct and distantly related to the Andaman Islanders), in varying proportions.

Moorjani et al. (2013): large-scale mixing of ANI and ASI took place roughly 4,200 to 1,900 years ago, after which endogamy froze much of the structure, a genetic signature of caste endogamy.

Narasimhan et al. (Science, 2019) and Shinde et al. (Cell, 2019): the genome from Rakhigarhi showed Harappan-related ancestry made of Iranian-related farmer and South Asian hunter-gatherer components, without Steppe ancestry; Steppe-related ancestry entered later, in the second millennium BCE.

Andamanese lineages: mitochondrial haplogroups M31 and M32 among the Onge and Great Andamanese (Thangaraj et al., Science, 2005) point to an early coastal dispersal from Africa tens of thousands of years ago.

Austro-Asiatic speakers: the Munda-speaking tribes carry a paternal lineage (Y-haplogroup O2a) shared with Southeast Asia, while their maternal lineages are largely local, showing male-mediated migration.

Conclusion: genes, language and physical type do not map neatly onto one another; India is a population of mixtures, which supports the UNESCO statements on race (from 1950) that race is not a fixed biological category.

4. Linguistic Elements

Census 2011: 19,569 raw mother-tongue returns were rationalised into 1,369 mother tongues and grouped into 121 languages, 22 in the Eighth Schedule and 99 non-scheduled languages with at least 10,000 speakers.

Language families (Language Atlas of India, Census 2011): Indo-European 78.07%, Dravidian 19.64%, Austro-Asiatic 1.11%, Tibeto-Burman 1.01%, with a very small Semito-Hamitic share; the Andamanese languages are often treated as a separate family and Nihali of central India as an isolate.

Indo-Aryan branch: Hindi was the mother tongue of 43.63% of the population in 2011, followed by Bengali 8.03%, Marathi 6.86%, Gujarati 4.58% and Urdu 4.19%; tribal Indo-Aryan speech includes Bhili and Halbi.

Dravidian: Telugu (6.70%), Tamil (5.70%), Kannada and Malayalam, and tribal languages such as Gondi, Kurukh (Oraon), Malto (Sauria Paharia), Kui (Kondh), Toda and Kota; Brahui in Balochistan shows the family's old western spread.

Austro-Asiatic: the Munda branch (Santali, Mundari, Ho, Kharia, Sora, Korku, Juang) in central and eastern India, Khasi and Pnar of the Mon-Khmer branch in Meghalaya, and Nicobarese.

Tibeto-Burman: Bodo, Garo, Mizo, Kokborok, Meitei (Manipuri), the Naga languages, Lepcha, Bhutia and Ladakhi in the north-east and Himalaya.

Policy milestones: George Grierson's Linguistic Survey of India (1894 to 1928); linguistic reorganisation of states (States Reorganisation Act, 1956); Bodo, Dogri, Maithili and Santali added to the Eighth Schedule by the 92nd Amendment (2003); Santali uses the Ol Chiki script devised by Raghunath Murmu.

Endangerment: many tribal languages are endangered; the death of Boa Sr in January 2010 ended the Bo language of the Great Andamanese.

5. Theory and Debates

Race versus language: Max Müller himself warned that Aryan is a linguistic term, not a racial one; confusing the two produced the racial theory of caste.

The Aryan question (debated in public discussion): linguistic and ancient-DNA evidence supports Steppe-related gene flow in the second millennium BCE, while indigenist views reject migration; examiners expect you to state the scientific consensus and mark the debate.

Unity in diversity: K.S. Singh's People of India project (Anthropological Survey of India, launched 1985) identified 4,635 communities and reported widespread sharing of traits, dialects and customs across religious and regional lines.

Critique of typology: modern biological anthropology replaces fixed racial types with clines and population genetics (see Paper I), so present Guha's scheme as historical and add the genetic evidence.

6. Diagrams to Draw

Tree of Guha's classification: one root (Indian population) branching into six boxes, with the Mongoloid, Mediterranean and Western brachycephal boxes each splitting into three sub-types.

Two outline maps of India: one shading Negrito (Andaman Islands), Proto-Australoid (central and southern hills), Mongoloid (north-east and Himalaya), Mediterranean (plains) and Nordic (north-west).

The second map shows Indo-Aryan across the north and west, Dravidian in the south with islands of Gondi and Kurukh in central India, the Austro-Asiatic belt (Chotanagpur, Meghalaya, Nicobar) and Tibeto-Burman in the north-east and Himalaya.

7. Using It in the Exam

10 marks (150 words): list Guha's six elements with one tribe each and one line on the genetic evidence.

15 marks (200 words): compare Risley and Guha, then show the four language families with percentages and tribal examples.

20 marks (250 words): physical classifications, genetic ancestry (ANI-ASI, Rakhigarhi), language families and distribution, then a critical conclusion on mixture and unity in diversity; add both maps.

Keywords: nasal index, Proto-Australoid, ANI-ASI admixture, Austro-Asiatic, endogamy, People of India project.

Quotable: Reich and colleagues concluded, in paraphrase, that nearly all Indian groups are mixtures of two highly differentiated ancestral populations.

1. Concepts and Definitions

Sources: the scheme comes from the Vedas, the Upanishads, the Dharmasutras and Dharmashastras (Manusmriti, Yajnavalkya Smriti) and the epics; it is a normative ideal, not a description of how every community lived.

Varna: the fourfold division into Brahmana, Kshatriya, Vaishya and Shudra; the Purusha Sukta (Rig Veda X.90) describes them as born from the mouth, arms, thighs and feet of the cosmic being.

Varna is an all-India ideal model, while jati (caste) is the local, endogamous, ranked unit actually found in villages; M.N. Srinivas warned that the varna model often distorts the reality of jati.

Ashrama: four stages of life for twice-born men: brahmacharya (celibate student), grihastha (householder), vanaprastha (forest-dweller, gradual withdrawal) and sannyasa (renunciation); the word comes from shram, effort.

Varnashrama dharma: duty fixed by one's varna and stage of life (svadharma); the Bhagavad Gita (3.35) says it is better to do one's own dharma imperfectly than another's well.

Purushartha: four goals of life: dharma (righteous duty), artha (wealth and power), kama (desire and pleasure) and moksha (liberation); the first three form the trivarga, and dharma regulates artha and kama.

Karma: action and its moral consequence; the doctrine holds that present birth, status and fortune result from deeds in past lives, first developed in the early Upanishads such as the Brihadaranyaka.

Rebirth (punarjanma) and samsara: the soul (atman) passes through repeated births until liberation; the Chandogya Upanishad says, in paraphrase, that those of good conduct are reborn in good wombs (Brahmin, Kshatriya, Vaishya) and those of evil conduct in evil wombs, tying rebirth to caste rank.

Rina (sacred debts): the Taittiriya Samhita names three debts: deva rina to the gods (repaid by sacrifice), rishi rina to the sages (by Vedic study) and pitri rina to the ancestors (by begetting a son and performing shraddha); the Shatapatha Brahmana adds a debt to fellow humans (hospitality).

Pancha mahayajna: the householder's five daily offerings: to Brahman (study), the gods, the ancestors, all beings (bhuta) and guests (nri).

Samskaras: life-cycle rites, conventionally sixteen, from conception to cremation; upanayana (sacred thread) marks the twice-born boy's entry into brahmacharya.

Kinds of dharma: the texts distinguish sadharana dharma (universal duties such as truth, non-violence and self-control) from varnashrama dharma (duties specific to varna and stage) and apad dharma (rules relaxed in times of distress).

2. How the Parts Fit Together

Varna organises society, ashrama organises the individual life course, purushartha gives the goals of each stage, rina defines obligations, and karma-rebirth supplies the moral explanation; together they form an integrated value system.

The grihastha stage is the pivot: Manu calls the householder the support of all other orders, because he produces wealth, offspring and offerings (paraphrase).

Each stage stresses a goal: brahmacharya builds dharma through learning, grihastha pursues artha and kama within dharma, vanaprastha and sannyasa prepare for moksha.

Functions: division of labour, social order, motivation through hope of a better rebirth, legitimation of inequality, and continuity between generations (pitri rina explains the importance of sons and of shraddha).

Exclusions: the ashrama scheme applied fully only to twice-born men; Shudras and women were denied upanayana, and women's duties were framed as stridharma (devotion to husband and household).

3. Analysis: Practice and Change

Gap between ideal and reality: few people ever followed all four ashramas; vanaprastha is now replaced by retirement, and sannyasa survives as a specialist religious path.

Persistence: purushartha language is still used in ethical discourse, karma is invoked to explain misfortune, and shraddha and pind-daan at Gaya continue the pitri rina idea.

Legal change: the Hindu Marriage Act (1955) allowed divorce, making marriage partly a contract, and the Hindu Succession Act (1956, amended 2005) gave daughters coparcenary rights, weakening the son-centred logic of the pitri rina.

Bhakti and reform: Bhakti saints such as Kabir, Ravidas and Tukaram, and later the Brahmo Samaj and Arya Samaj, rejected birth-based ranking while keeping devotion and ideas of karma.

Tribal contrast: most tribal worldviews have no varna or ashrama; L.P. Vidyarthi's nature-man-spirit complex describes their cosmology, though Sanskritization spreads karma and rebirth ideas among tribes such as the Bhumij and Gond.

Ethnography of karma: Ursula Sharma ('Theodicy and the doctrine of karma', Man, 1973) argued that villagers in Himachal Pradesh invoke karma selectively, alongside fate, gods and witchcraft, rather than as a complete explanation.

4. Theory and Debates

Max Weber (The Religion of India, 1916 to 1917): called the karma doctrine, in effect, the most consistent theodicy ever produced, because it explained every inequality as earned; he argued it discouraged rational economic change, a view later contested by Milton Singer's study of Madras industrial leaders.

Louis Dumont (Homo Hierarchicus, 1966; English 1970): Indian society is ordered by the opposition of pure and impure, with the Brahmin's status encompassing the king's power; the renouncer is the individual outside the world and the creative source of Indian religions.

P.H. Prabhu (Hindu Social Organization, 1940s): treated the ashramas and purusharthas as a psycho-moral plan for training and fulfilling the individual.

K.M. Kapadia (Marriage and Family in India, 1955): showed that Hindu marriage was a sacrament tied to dharma, praja (progeny) and rati, in that order of importance, and to repaying pitri rina.

McKim Marriott (1976): his ethnosociology described Hindus as dividuals who exchange substance-codes through food, marriage and service, an alternative to Dumont's pure-impure model.

M.N. Srinivas (Religion and Society among the Coorgs of South India, 1952): showed that the varna scheme serves as a frame of reference through which local jatis claim higher rank by Sanskritization.

Critics: Jyotiba Phule (Gulamgiri, 1873) and B.R. Ambedkar (Annihilation of Caste, 1936) rejected shastric legitimation of inequality and treated karma theory as an ideology of domination.

Debated point: whether these texts describe society or prescribe an upper-caste ideal; most anthropologists treat them as ideology to be compared with field data.

5. Diagrams to Draw

Ashrama table: four columns (stage, approximate age, duties, main purushartha), for example brahmacharya, up to about 25, study and celibacy, dharma.

Cycle of samsara: draw a circle with arrows: birth, action (karma), death, rebirth decided by karma; draw one arrow leaving the circle labelled moksha.

Purusha Sukta figure: a simple human outline labelled mouth (Brahmana), arms (Kshatriya), thighs (Vaishya) and feet (Shudra), with a note that jatis are the real units.

Integration chart: five boxes joined by arrows: varna (society), ashrama (individual life course), purushartha (goals), rina (obligations) and karma-rebirth (legitimation).

6. Using It in the Exam

10 marks (150 words): define one concept (for example rina), give its textual source and its social function, with one modern example.

15 marks (200 words): explain how varna, ashrama and purushartha form one system, then add Dumont or Weber.

20 marks (250 words): concepts, integration, functions, critique (Phule, Ambedkar, feminist critique), ethnographic reality (Sharma, Srinivas) and present relevance.

Keywords: svadharma, trivarga, theodicy, purity and pollution, renouncer, pitri rina.

Quotable: Dumont's core idea, paraphrased: hierarchy in India is the encompassing of the contrary, with ritual status ranking above political power.

1. Demographic Profile of India

Example 1 (UPSC 2025, 15 marks): Elucidate the role of demographic and social factors for population growth in India.

Paper and question: Paper II, Q4(b)

Approach: Elucidate two sets of factors behind India's population growth: demographic (mortality decline, fertility, age structure, momentum, migration) and social (marriage, son preference, education, religion and region, economy), with data, then a conclusion.

India's population rose from about 36 crore in 1951 to 121.09 crore in Census 2011, and by UN estimates India became the most populous country in 2023; decadal growth fell to 17.7 percent in 2001–11, the lowest since independence.

Demographic factors: after 1921, the 'year of the great divide', death rates fell with famine relief, disease control and vaccines while birth rates stayed high, as Kingsley Davis (1951) showed; high infant mortality encouraged insurance births; a young age structure gives population momentum, so numbers keep rising even though the TFR fell to 1.9 (SRS 2023); and growth is almost wholly natural increase, with migration redistributing people between states.

Social factors: near-universal and early marriage (NFHS-5: 23.3 percent of women aged 20–24 married before 18); son preference rooted in patriliny, dowry and the son's role in shraddha and repaying pitri rina; low female literacy and autonomy; the economic value of children in agrarian and tribal households, which Mamdani's Khanna study (1972) highlighted; and religious and regional norms, with fertility differences narrowing once education is held constant.

Regional contrast shows the role of these factors: Kerala and Tamil Nadu reached low fertility through female education and health care, while Bihar's TFR remained the highest at 2.8 (SRS 2023).

Demographic factors explain the speed of growth and social factors its persistence; continued investment in girls' education, health and old-age security will bring stabilisation.

Example 2 (UPSC 2024, 15 marks): What are the demographic challenges of India's changing population dynamics in the next 50 years ?

Paper and question: Paper II, Q4(c)

Approach: Identify India's main demographic challenges over the next five decades (regional divergence, ageing, dividend and jobs, sex ratio, migration and urbanisation, federal issues, vulnerable tribal groups), with data and a way forward.

India has passed replacement fertility (TFR 2.0 in NFHS-5, 2019–21, and 1.9 in SRS 2023) but, because of momentum, UN projections expect its population to keep growing for decades before peaking around the 2060s. The next fifty years will therefore bring changes in composition more than in size.

Ageing: the share aged 60 and above was 8.6 percent in Census 2011 and is projected to exceed 20 percent by 2050 (UNFPA India Ageing Report 2023), with more elderly women, widows and people living alone, straining pensions and health care. Demographic dividend: the working-age bulge peaks in the coming decades, and without jobs, skills and female labour participation it may become a burden.

Regional divergence: southern states such as Kerala and Tamil Nadu are ageing fast, while Bihar and Uttar Pradesh remain young, driving north-to-south migration and raising the delimitation question after the freeze ends with the first census after 2026. Gender imbalance: a child sex ratio of 918 (Census 2011) produces marriage squeezes and bride migration.

Urbanisation and environment: a majority urban population is expected within decades, pressing on water, housing and climate resilience. Tribal and vulnerable groups: PVTGs such as the Great Andamanese, Onge and Jarawa are tiny populations at risk, and tribal areas lag in health indicators.

The way forward: region-specific policies, skilling and women's jobs, universal health and pension cover, and planning with the caste-inclusive Census 2027.

Example 3 (UPSC 2021, 15 marks): Delineate the factors influencing fertility in Indian population.

Paper and question: Paper II, Q6(c)

Approach: Delineate biological, socio-cultural, economic and policy factors that influence fertility in India, using the proximate determinants and Indian data and examples.

Fertility, the actual number of births, has fallen steeply in India, from a TFR of about 6 in the 1950s to 2.0 in NFHS-5 (2019–21) and 1.9 in SRS 2023, but with wide differences between regions and groups. Following Davis and Blake (1956), social factors act through intermediate variables of marriage, contraception and pregnancy outcome.

Biological: age at menarche, fecundity, breastfeeding (which spaces births), anaemia and infections such as genital tuberculosis that cause sterility.

Socio-cultural: early and universal marriage; son preference linked to patriliny, dowry and pitri rina, so couples continue until a son is born; low status and education of women (NFHS-5 TFR about 2.8 for women with no schooling against about 1.8 with 12 or more years); joint family pressures; and religion and caste, whose differences shrink with education. Tribal norms vary: bride price and women's work coexist with high fertility in some groups and very low fertility in small PVTGs.

Economic and policy: the value of child labour in agriculture (Mamdani, 1972); urbanisation and rising costs of schooling; income and media exposure; and the family planning programme since 1952, which relies heavily on female sterilisation, with the coercive drive of 1975–77 provoking resistance.

Fertility in India is thus bio-cultural: female education, later marriage and health services explain the fall, while son preference and poverty explain where it remains high.

Example 4 (UPSC 2018, 15 marks): What are the various factors influencing population growth in India? Discuss.

Paper and question: Paper II, Q4(b)

Approach: Discuss the factors of population growth in India in phases (history of growth), then demographic, socio-cultural, economic and policy factors, with data, and conclude with present trends.

India's population growth passed through four phases: stagnant (1901–21, famines, plague and the 1918 influenza), steady growth (1921–51), rapid 'population explosion' (1951–81, decadal growth above 21 percent) and high but slowing growth (1981–2011, falling to 17.7 percent in 2001–11).

Demographic factors: the fall in mortality from better food distribution, public health and vaccines, while fertility lagged, the gap that demographic transition theory predicts; high infant mortality prompting more births; and a young age structure creating momentum.

Socio-cultural factors: universal and early marriage, son preference and the ritual value of sons, low female literacy (65.46 percent in Census 2011), joint family norms, and religious attitudes to contraception.

Economic factors: children as labour and old-age security in agrarian economies (Caldwell's wealth flows, Mamdani's Khanna study), poverty, and rural residence (68.8 percent rural in 2011). Policy: the world's first national family planning programme (1952), the National Population Policy 2000, and uneven service delivery across states.

Diagram: India's population pyramid for 2011, broad at the base and narrowing upward.

With TFR now below replacement nationally, future growth depends mainly on momentum and on the high-fertility northern states, so female education and health remain central.

Example 5 (UPSC 2017, 20 marks): Give your assessment of the reasons for the imbalance in the sex-ratio in India.

Paper and question: Paper II, Q8(a)

Approach: Assess the reasons for India's adverse sex ratio: present the data and regional pattern, then biological, socio-cultural, economic, technological and mortality-related causes, contrast tribal populations, and evaluate policy responses.

India's sex ratio, expressed as females per 1,000 males, was 943 in Census 2011, and the child sex ratio (0–6 years) fell to 918, the lowest recorded. The imbalance is sharpest in the north-west: Haryana had an overall ratio of 879 and a child sex ratio of 834, while Kerala's overall ratio was 1,084. Amartya Sen (1990) drew attention to such 'missing women'.

Biological baseline: about 105 boys are born per 100 girls everywhere, but females survive better at most ages, so a deficit beyond this signals social causes.

Socio-cultural causes: son preference rooted in patrilineal descent, patrilocal residence and inheritance by sons; dowry, which makes daughters a burden; and the son's ritual role in the funeral and in repaying pitri rina. Barbara Miller (The Endangered Sex, 1981) linked the northern deficit to the low value of female labour in plough agriculture, and Dyson and Moore (1983) to northern kinship systems restricting women's autonomy.

Technological and mortality causes: sex-selective abortion after ultrasound spread from the 1980s, especially among prosperous families wanting few children; neglect of girls in nutrition and health care; maternal mortality; and past female infanticide. Male-dominated migration also skews urban ratios.

Tribal contrast: the Scheduled Tribe sex ratio was 990 and child sex ratio 957 in Census 2011, reflecting women's economic role, bride price and weaker son preference, though Sanskritization may erode this.

Assessment: the PCPNDT Act (1994, amended 2003) and Beti Bachao Beti Padhao (2015) have helped, and NFHS-5 (2019–21) reported an overall ratio above 1,000 and a sex ratio at birth of 929; but enforcement is weak and the root, son preference, is cultural, so daughters' inheritance rights (Hindu Succession Amendment, 2005), education and employment matter most.

2. Ethnic and Linguistic Elements in the Indian Population

Example 6 (UPSC 2026, 10 marks): Dravidian language family and its tribal speakers.

Paper and question: Paper II, Q1(a)

Approach: A short note: the Dravidian family, its sub-groups, distribution and the tribal languages within it, with figures.

The Dravidian language family, recognised by F.W. Ellis (1816) and named by Robert Caldwell in his comparative grammar (1856), was spoken by 19.64 percent of Indians in Census 2011, the second largest family after Indo-European.

Its four sub-groups are South (Tamil, Malayalam, Kannada, Tulu, Kodava, Toda, Kota, Irula), South-Central (Telugu, Gondi, Kui, Kuvi, Konda, Pengo), Central (Kolami, Parji, Ollari, Naiki) and North (Kurukh, Malto, Brahui).

Tribal speakers: the Gond speak Gondi (about 29.8 lakh speakers in 2011) across Madhya Pradesh, Maharashtra, Chhattisgarh and Telangana; the Oraon speak Kurukh (about 19.9 lakh) in Jharkhand, Odisha and Chhattisgarh; the Sauria Paharia speak Malto in the Rajmahal hills; the Kondh speak Kui and Kuvi in Odisha; the Kolam speak Kolami; and the Toda, Kota and Irula of the Nilgiris speak South Dravidian languages.

These islands of Dravidian speech in central and eastern India, with Brahui in Balochistan, suggest a once wider spread; many tribal Dravidian languages are unwritten and declining under pressure from regional languages.

Example 7 (UPSC 2026, 15 marks): Why the classifications of Indian populations, based on somatometric and somatoscopic characteristics failed to develop a common understanding of the population diversity ?

Paper and question: Paper II, Q4(b)

Approach: Explain why classifications based on body measurements and observed traits (Risley, Guha, Sarkar and others) disagreed: methodological, conceptual and biological reasons, then what replaced them.

Between 1900 and the 1960s, H.H. Risley (seven types, 1901–08), A.C. Haddon, Egon von Eickstedt, B.S. Guha (six races with nine sub-types, 1935–44) and S.S. Sarkar (six elements, 1954) classified Indians using somatometry (stature, cephalic and nasal indices) and somatoscopy (skin colour, hair form, eye fold). Each produced a different scheme, and no common understanding emerged.

Methodological reasons: small, unrepresentative samples, often of convenient castes; different instruments and landmarks; subjective scoring of skin and hair; and averages that hide large overlaps between groups.

Biological reasons: these traits are polygenic and plastic, changing with nutrition, climate and the secular trend; head shape changes even between generations, as Franz Boas showed among immigrants (1912); traits vary in clines rather than clusters, and different traits give different boundaries.

Conceptual reasons: the idea of pure races mixing over time was assumed, not shown; names mixed race with language (Risley's 'Dravidian', 'Scytho-Dravidian'); caste and race were wrongly equated; and colonial administrative aims shaped questions. Different authors also weighed different traits, so Guha found a Negrito element in the south that Sarkar rejected.

Population genetics replaced typology: blood groups (D.N. Majumdar), then DNA studies such as Reich and colleagues (2009) showed most Indians are mixtures of Ancestral North and South Indians, and the UNESCO statements on race (from 1950) rejected fixed races, explaining why typological schemes could never agree.

Example 8 (UPSC 2025, 15 marks): Delineate the major features of S. S. Sarkar's classification of Indian populations. Was his classification better than Risley? Explain.

Paper and question: Paper II, Q2(b)

Approach: Delineate the main features of S.S. Sarkar's classification (basis, elements, distinctive positions), then compare it with Risley's and judge which was better, with reasons.

S.S. Sarkar (Sasanka Sekhar Sarkar) of the Anthropological Survey of India presented his scheme in The Aboriginal Races of India (1954) and later writings.

Features: it was based mainly on the cephalic index, supported by stature, nasal index, other measurements and blood groups; it found India predominantly long-headed with notable broad-headed elements; and it recognised six ethnic elements: Australoid, Indo-Aryan, Irano-Scythian, Mundari-speaking, Far Eastern and Mongolian. He treated the Australoid (Veddid) element as the autochthonous base of the tribal population, from which Dravidian speakers later developed, and his team's study of the Kadar (1959) found no Negrito element on the mainland.

Risley's scheme (Census 1901; The People of India, 1908) gave seven types, Turko-Iranian, Indo-Aryan, Scytho-Dravidian, Aryo-Dravidian, Mongolo-Dravidian, Mongoloid and Dravidian, based chiefly on the nasal index, and linked caste rank to nose form.

Was Sarkar better? Largely yes: he used more traits including serology, gave the tribal (Australoid) substratum its due place, avoided Risley's race-caste equation, and tested claims such as the Negrito with field data. But he still used typological racial categories, mixed language with race ('Mundari-speaking'), and relied heavily on one index whose plasticity is now known.

Sarkar's scheme was thus an advance on Risley's, but both are now historical; genetic studies of ANI-ASI admixture give a far better picture of Indian diversity.

Example 9 (UPSC 2023, 15 marks): Critically compare Risley's and Sarkar's approaches to the classification of peoples of India.

Paper and question: Paper II, Q4(b)

Approach: Critically compare the two approaches on basis, method, categories, assumptions and treatment of caste and tribes, ideally in a comparison table, then evaluate both.

H.H. Risley, Census Commissioner for 1901, and S.S. Sarkar of the Anthropological Survey of India represent the colonial and the early post-independence phases of physical classification of Indian peoples.

Basis and method: Risley measured large numbers of people of different castes in Bengal and northern India and relied mainly on the nasal index, with cephalic index and stature; Sarkar (1954) relied mainly on the cephalic index, adding other measurements and blood groups, and paid special attention to tribes.

Categories: Risley's seven types, Turko-Iranian, Indo-Aryan, Scytho-Dravidian, Aryo-Dravidian, Mongolo-Dravidian, Mongoloid and Dravidian, mostly mixtures of three base stocks; Sarkar's six elements, Australoid, Indo-Aryan, Irano-Scythian, Mundari-speaking, Far Eastern and Mongolian.

Assumptions: Risley held that caste originated in race and that social status varied inversely with nasal width, a view G.S. Ghurye (1932) accepted only partly for the north; Sarkar did not tie caste to race, saw the Australoid as the indigenous base, and denied a mainland Negrito element.

Diagram: a two-column table comparing Risley and Sarkar on criteria, categories, view of caste and view of tribes.

Evaluation: Risley's work was shaped by colonial ethnology and served administrative classification, and his mixed linguistic-racial labels lack evidence; Sarkar was more cautious and field-based, but both relied on plastic metric traits and fixed types. Modern genetics, showing clines and admixture, supersedes both.

Example 10 (UPSC 2023, 10 marks): Dravidian languages and their subgroups

Paper and question: Paper II, Q5(d)

Approach: A short note: origin of the family, the four sub-groups with members, numbers and distribution.

Dravidian languages form India's second largest family, spoken by 19.64 percent of the population (Census 2011); the family was identified by F.W. Ellis (1816) and named by Robert Caldwell (1856), and Bhadriraju Krishnamurti's The Dravidian Languages (2003) gives the standard classification.

South Dravidian: Tamil, Malayalam, Kannada, Tulu, Kodava, and the Nilgiri languages Toda, Kota and Irula. South-Central Dravidian: Telugu, Gondi, Konda, Kui, Kuvi, Pengo and Manda.

Central Dravidian: Kolami, Naiki, Parji and Ollari (Gadaba) in Maharashtra, Telangana, Chhattisgarh and Odisha. North Dravidian: Kurukh (Oraon) and Malto (Sauria Paharia) in Jharkhand and neighbouring states, and Brahui in Balochistan.

The four literary languages, Tamil (classical status 2004), Telugu and Kannada (2008) and Malayalam (2013), dominate the south, while the central and northern sub-groups are largely tribal languages such as Gondi and Kurukh, many of them endangered.

Example 11 (UPSC 2022, 15 marks): Describe the methods adopted by Sir Herbert Hope Risley in classifying Indian populations. What are the criticisms against Risley's classification?

Paper and question: Paper II, Q3(c)

Approach: Describe Risley's methods (anthropometric survey, indices, sampling, the seven types and his caste theory), then the criticisms (methodological, conceptual, political), ending with an assessment.

Sir Herbert Hope Risley, an ICS officer and Census Commissioner for 1901, wrote The Tribes and Castes of Bengal (1891) and The People of India (1908), the first attempt at an all-India racial classification.

Methods: anthropometric measurement, following the French anthropologist Paul Topinard's techniques, of several thousand individuals from castes and tribes, chiefly in Bengal, the North-Western Provinces and Punjab; he relied most on the nasal index, with the cephalic index, stature and somatoscopic observation; he arranged castes by average nasal index and grouped people into seven types: Turko-Iranian, Indo-Aryan, Scytho-Dravidian, Aryo-Dravidian, Mongolo-Dravidian, Mongoloid and Dravidian. He concluded that a caste's social rank varied inversely with its nasal index, so that race explained the origin of caste.

Criticisms: samples were small and regionally limited, yet generalised to all India; nasal and cephalic indices are plastic and overlap widely; labels mixed language and race (Dravidian is a language family); the 'Scytho-Dravidian' type had no evidence of Scythian ancestry; G.S. Ghurye (Caste and Race in India, 1932) showed the race-caste link held at most in the north; and the scheme ignored serological evidence.

Critics also see political aims: ranking castes in the 1901 Census hardened caste identities, and the scheme fitted colonial ideas of race.

Risley's survey was pioneering data collection, but his racial theory of caste is rejected; Guha, Sarkar and modern genetics superseded it.

Example 12 (UPSC 2022, 10 marks): Austroasiatic languages

Paper and question: Paper II, Q5(e)

Approach: A short note: the family, its branches in India with tribal speakers, numbers and distribution, and genetic or historical links.

Austro-Asiatic is a language family spread from India to Vietnam and Cambodia; in India it was spoken by 1.11 percent of the population in Census 2011, almost entirely by tribal communities.

Munda branch (central and eastern India): North Munda, Santali, Mundari, Ho, Bhumij, Birhor, Asur and Korku; and South Munda, Kharia, Juang, Sora (Savara), Gutob (Gadaba) and Remo (Bondo). Santali is the largest, with about 73 lakh speakers in 2011, and entered the Eighth Schedule in 2003; it uses the Ol Chiki script devised by Raghunath Murmu.

Khasian (Mon-Khmer) branch: Khasi, Pnar (Jaintia), War and Lyngngam in Meghalaya. Nicobarese in the Nicobar Islands.

Munda speakers share a paternal lineage (Y-haplogroup O2a) with South-East Asia but largely local maternal lineages, suggesting male-mediated migration; Kuiper (1948) and others traced Munda loanwords in Sanskrit. Many smaller Munda languages, such as Asur and Birhor, are endangered.

Example 13 (UPSC 2020, 10 marks): Debates on 'Aryan' invasion

Paper and question: Paper II, Q1(b)

Approach: A short note: the invasion theory and its origin, the evidence against invasion, the migration model with linguistic and genetic evidence, and the indigenist counter-view; mark it as debated.

The Aryan invasion theory, shaped by nineteenth-century philology (Max Müller, who himself said Aryan was a linguistic, not racial, term), held that Indo-Aryan-speaking warriors conquered the subcontinent; Mortimer Wheeler linked it to the end of the Harappan cities.

Against invasion: George Dales (1964) called the Mohenjo-daro 'massacre' mythical; Harappan decline was gradual and ecological; and there is no archaeological layer of conquest. Indigenist writers argue that Indo-Aryan speech originated in India (the 'Out of India' view).

Migration model: the close relationship of Sanskrit to Avestan and other Indo-European languages, and ancient DNA, support gradual migrations rather than invasion: Narasimhan and colleagues (2019) found steppe-related ancestry entering South Asia in the second millennium BCE, after the mature Harappan phase, while the Rakhigarhi genome (2019) lacked it.

The scholarly consensus now favours migration and cultural mixing over conquest, but the subject remains politically sensitive and debated in public discourse.

Example 14 (UPSC 2020, 10 marks): Dravidian languages

Paper and question: Paper II, Q1(d)

Approach: A short note: the family, sub-groups with examples, distribution and speakers, and cultural features.

The Dravidian family, named by Robert Caldwell (1856), is India's second largest, with 19.64 percent of speakers (Census 2011), concentrated in the south but with tribal pockets in central and eastern India.

Sub-groups: South (Tamil 5.70 percent, Malayalam, Kannada, Tulu, Toda), South-Central (Telugu 6.70 percent, Gondi, Kui), Central (Kolami, Parji) and North (Kurukh, Malto, and Brahui in Balochistan).

Features: agglutinative grammar, retroflex consonants that also entered Indo-Aryan, and an ancient literature, the Tamil Sangam corpus of the early centuries CE; Tamil became India's first classical language in 2004. Dravidian kinship terminology, which distinguishes cross from parallel cousins and favours cross-cousin marriage (Thomas Trautmann, Dravidian Kinship, 1981), is a major anthropological marker.

Some scholars, such as Asko Parpola, propose that the Harappans spoke a Dravidian language, but this remains unproven.

Example 15 (UPSC 2019, 10 marks): Distribution of Tibeto-Burman group of languages in India.

Paper and question: Paper II, Q1(c)

Approach: A short note: the family, its share, region-wise distribution with major languages and tribes, and status issues; a map helps.

The Tibeto-Burman branch of the Sino-Tibetan family was spoken by 1.01 percent of Indians in Census 2011, but it has the largest number of distinct languages of any family in India, concentrated along the Himalaya and in the north-east.

Western and central Himalaya: Ladakhi, Balti and Tibetan in Ladakh; Lahauli and Kinnauri in Himachal Pradesh; and Bhutia and Lepcha in Sikkim. Arunachal Pradesh: the Tani languages of the Adi, Nyishi, Apatani and Mishing, and Monpa and Sherdukpen.

Assam and Meghalaya: the Bodo-Garo group, Bodo, Dimasa, Garo, Rabha and Tiwa, and Karbi. Nagaland and Manipur: the many Naga languages (Ao, Angami, Konyak, Lotha, Sema) and Meitei (Manipuri). Mizoram and Tripura: the Kuki-Chin languages such as Mizo, and Kokborok in Tripura.

Manipuri (1992) and Bodo (2003) are in the Eighth Schedule, but most Tibeto-Burman languages are small, often unwritten and listed as endangered by UNESCO, and the boundaries between language and dialect are frequently contested.

Example 16 (UPSC 2018, 10 marks): Endangered Languages

Paper and question: Paper II, Q1(c)

Approach: A short note: what makes a language endangered, Indian scale and examples, causes, and measures taken.

A language is endangered when children no longer learn it as a mother tongue and its speakers shift to a dominant language; UNESCO grades vitality from vulnerable to critically endangered and extinct.

UNESCO's Atlas of the World's Languages in Danger (2009) listed 197 Indian languages, the largest number for any country. Most are tribal, such as the Great Andamanese languages (Bo died with Boa Sr in 2010), Onge, Toda, Birhor, Asur and many north-eastern languages; the Census counts only languages with 10,000 or more speakers, hiding many small ones.

Causes: small populations, schooling only in state languages, migration, market pressure, loss of land and forest life that carries vocabulary, and low prestige.

Measures: the Scheme for Protection and Preservation of Endangered Languages (2013) of the Central Institute of Indian Languages, Mysuru; mother-tongue education under the National Education Policy 2020; scripts such as Ol Chiki for Santali; and the UN International Decade of Indigenous Languages (2022–2032). Language loss is also loss of ecological and cultural knowledge.

Example 17 (UPSC 2017, 10 marks): Austro-asiatic linguistic groups in India.

Paper and question: Paper II, Q1(b)

Approach: A short note: Austro-Asiatic groups in India by branch and region, with numbers and features.

Austro-Asiatic speakers formed 1.11 percent of India's population in Census 2011 and are regarded by many scholars as among the oldest linguistic groups of eastern India.

Munda groups of the Chota Nagpur plateau and adjoining Odisha, West Bengal and Madhya Pradesh: Santal, Munda, Ho, Bhumij, Birhor and Asur (North Munda), Korku of the Satpuras, and Kharia, Juang, Saora, Gadaba and Bondo (South Munda).

Khasi groups of Meghalaya, the Khasi, Pnar (Jaintia), War and Lyngngam, matrilineal communities speaking Mon-Khmer languages; and the Nicobarese of the Nicobar Islands.

Santali, with about 73 lakh speakers (2011), is the largest and is in the Eighth Schedule (2003). Shared traits include megalithic memorials, rice cultivation and similar kin terms, and genetic studies point to links with South-East Asia; the smaller languages are endangered.

Example 18 (UPSC 2016, 10 marks): Linguistic elements in Indian population

Paper and question: Paper II, Q1(b)

Approach: A short note: India's linguistic diversity by Census 2011 figures, the four families with shares and tribal examples, and its significance.

India's linguistic diversity is vast: Census 2011 grouped 19,569 raw returns into 1,369 mother tongues and 121 languages (22 scheduled), and George Grierson's Linguistic Survey of India (1894–1928) first mapped it.

Indo-European (78.07 percent): Indo-Aryan languages of the north, west and east, including tribal Bhili and Halbi. Dravidian (19.64 percent): the south, with tribal Gondi, Kurukh and Kui in central India.

Austro-Asiatic (1.11 percent): Munda languages such as Santali and Ho, Khasi in Meghalaya and Nicobarese. Tibeto-Burman (1.01 percent): Bodo, Garo, Mizo, Meitei and the Naga languages of the north-east and Himalaya. The Andamanese languages form a separate group, and Nihali of central India is an isolate.

Tribes speak languages of every family, so language does not coincide with race or religion; long contact has produced shared features across families, making India a 'linguistic area' (Murray Emeneau, 1956).

Example 19 (UPSC 2016, 15 marks): Give a critical assessment of 'Negrito Problem' in India.

Paper and question: Paper II, Q3(b)

Approach: Critically assess the 'Negrito problem': the claim, who supported and opposed it, the evidence (morphological, serological, genetic), and a balanced conclusion.

The Negrito problem is the question whether a short, dark-skinned, frizzy-haired population, like the Negritos of South-East Asia (Semang, Aeta), formed the earliest racial layer of India beyond the Andaman Islands.

The claim: the Onge, Jarawa, Great Andamanese and Sentinelese clearly show Negrito traits. B.S. Guha (1944) placed the Negrito first among India's racial elements and reported traces among the Kadar and Irula of the south, and J.H. Hutton reported frizzy hair among some Angami Nagas.

The counter-evidence: S.S. Sarkar's team (1959) studied the Kadar through anthropometry, blood groups, dermatoglyphics and hair and found no Negrito element, grouping them with Australoid tribes such as the Paniyan; frizzy hair in a few individuals may arise from local variation or admixture; and Sarkar held that mainland tribes are Australoid.

Genetic evidence: the Andamanese carry deep mitochondrial lineages (M31 and M32; Thangaraj and colleagues, 2005) from an early coastal dispersal out of Africa; Reich and colleagues (2009) found that the Ancestral South Indian component of mainland Indians is distantly related to the Andamanese, but not specifically 'Negrito'; and genomic work suggests that Negrito-like features in South-East Asia and the Andamans may reflect convergent adaptation to tropical forests rather than one race (debated).

Negritos are thus certain in the Andamans but unproven on the mainland; genetics reframes the 'problem' as one of early migration and shared deep ancestry.

Example 20 (UPSC 2015, 15 marks): Briefly describe the classical models of ethnic and linguistic classification of Indian population. Discuss its relevance today.

Paper and question: Paper II, Q2(b)

Approach: Briefly describe the classical racial (Risley, Guha, Sarkar) and linguistic (Grierson, Chatterji, Census) models, then discuss their relevance today in the light of genetics and policy.

Classical models classified Indians either by physical type or by language, both products of colonial and early national anthropology.

Racial models: H.H. Risley (1901–08), seven types based on the nasal index, linking caste to race; B.S. Guha (1935–44), six races, Negrito, Proto-Australoid, Mongoloid, Mediterranean, Western Brachycephals and Nordic, with nine sub-types, the most cited scheme; S.S. Sarkar (1954), six elements based on the cephalic index, denying a mainland Negrito.

Linguistic models: George Grierson's Linguistic Survey of India (1894–1928) and Suniti Kumar Chatterji's work grouped languages into Indo-Aryan, Dravidian, Austro-Asiatic and Tibeto-Burman families; Census 2011 gives their shares as 78.07, 19.64, 1.11 and 1.01 percent.

Relevance today: racial typologies are obsolete scientifically, since traits are clinal and plastic and the UNESCO statements reject fixed races; genetics (ANI-ASI admixture, Reich and colleagues, 2009) partly confirms their broad intuition of multiple ancestral streams but shows universal mixture. Linguistic classification remains highly relevant: it underlies the Eighth Schedule, linguistic states (1956), mother-tongue education and endangered-language policy, and correlates with some genetic lineages, such as Munda speakers and South-East Asian paternal links.

Classical models are thus valuable as history of the discipline and as a first map of diversity, but should be taught with genetic and linguistic updates, avoiding any link between race and social rank.

Example 21 (UPSC 2014, 10 marks): Major linguistic divisions of India

Paper and question: Paper II, Q1(d)

Approach: A short note: the four major families with shares, regions and examples, plus minor groups and a map.

India's languages belong to four major families, first mapped in George Grierson's Linguistic Survey of India (1894–1928); Census 2011 recorded 121 languages, 22 of them in the Eighth Schedule.

Indo-Aryan (Indo-European, 78.07 percent): Hindi (43.63 percent as mother tongue), Bengali, Marathi, Gujarati, Urdu, Punjabi and Odia across the north, west and east. Dravidian (19.64 percent): Telugu, Tamil, Kannada and Malayalam in the south, and Gondi and Kurukh in central India.

Austro-Asiatic (1.11 percent): Santali, Mundari, Ho and Khasi in Chota Nagpur and Meghalaya, and Nicobarese. Tibeto-Burman (1.01 percent): Bodo, Meitei, Garo, Mizo, the Naga languages, Ladakhi and Lepcha in the north-east and Himalaya. The Andamanese languages and the isolate Nihali stand apart.

Diagram: an outline map shading the four families, with Dravidian islands in central India.

These divisions do not match race or religion, and centuries of contact have created shared features, so India is both linguistically diverse and a single linguistic area.

Example 22 (UPSC 2014, 15 marks): Outline the distribution of Dravidian languages in India and describe their cultural significance.

Paper and question: Paper II, Q4(c)

Approach: Outline the distribution of Dravidian languages (literary south, tribal central and eastern pockets, Brahui), then describe their cultural significance (literature, kinship, religion and art, identity, prehistory debates).

The Dravidian family, identified by F.W. Ellis (1816) and named by Robert Caldwell (1856), is spoken by 19.64 percent of Indians (Census 2011) and has some 26 languages.

Distribution: the four literary languages fill the south, Telugu (Andhra Pradesh and Telangana), Tamil (Tamil Nadu and Puducherry), Kannada (Karnataka) and Malayalam (Kerala), with Tulu and Kodava in coastal and hill Karnataka; tribal pockets lie further north, Gondi in Madhya Pradesh, Maharashtra and Chhattisgarh, Kui and Kuvi among the Kondh of Odisha, Kolami in Maharashtra, Kurukh among the Oraon of Jharkhand and Malto in the Rajmahal hills; and Brahui in Balochistan, Pakistan.

Cultural significance: Tamil Sangam literature of the early centuries CE and its long classical tradition (Tamil was declared India's first classical language in 2004); Dravidian kinship terminology and cross-cousin marriage, analysed by Louis Dumont and Thomas Trautmann; temple architecture, Bharatanatyam, Kathakali and Carnatic music; contributions of retroflex sounds and loanwords to Sanskrit; and political identity through the Dravidian movement and linguistic states (1956).

Diagram: a map of India showing the southern Dravidian block with Gondi, Kui, Kurukh and Malto islands in central and eastern India.

The tribal pockets and Brahui suggest a once wider spread, and some scholars link the family to the Harappans (debated). Protecting tribal Dravidian languages is part of preserving this heritage.

3. Varnashrama, Purushartha, Karma, Rina and Rebirth

Example 23 (UPSC 2025, 10 marks): Varnashrama and its contemporary relevance

Paper and question: Paper II, Q5(d)

Approach: A short note: define varnashrama, then judge what remains relevant today and what has been rejected, with examples.

Varnashrama dharma is the Dharmashastra scheme of duties fixed by varna (Brahmana, Kshatriya, Vaishya, Shudra, traced to the Purusha Sukta, Rig Veda X.90) and by ashrama, the four life stages of brahmacharya, grihastha, vanaprastha and sannyasa; it was a normative ideal, not a description of how all Indians lived.

Varna today: birth-based ranking conflicts with Articles 14–17 of the Constitution, which abolish untouchability, and with the critiques of Phule and Ambedkar; the real units are jatis, as Srinivas stressed, though varna still frames claims to status through Sanskritization and appears in matrimonial and political discourse.

Ashrama today: the life-course idea remains meaningful: education as a stage of discipline, the householder as the economic and social pivot, and withdrawal in old age resembling retirement and pilgrimage, though few follow vanaprastha or sannyasa literally.

The relevance of varnashrama now lies in its ethic of duty and life-stage balance, not in hierarchy; anthropologists treat it as ideology to be compared with field reality.

Example 24 (UPSC 2023, 10 marks): Interface between Purushartha and Ashrama

Paper and question: Paper II, Q1(b)

Approach: A short note showing how each ashrama is linked to particular purusharthas, with the grihastha as pivot and moksha as the final goal.

The purusharthas are the four aims of life, dharma, artha, kama and moksha, and the ashramas are the four stages through which a twice-born man was expected to pursue them; together they form a plan for the whole life course, which P.H. Prabhu (Hindu Social Organization) called a psycho-moral scheme.

Brahmacharya (student) builds dharma through learning and discipline; grihastha (householder) pursues artha and kama within dharma, marrying, earning, begetting sons and supporting all other stages, which is why Manu called the householder the support of the other orders (paraphrase); vanaprastha (forest-dweller) loosens attachment and turns toward moksha; and sannyasa (renouncer) seeks moksha alone.

Dharma runs through every stage as the regulating value, so the scheme balances worldly life and liberation in sequence rather than opposing them; Louis Dumont saw the renouncer as the individual outside the world, a counterpoint to the man-in-the-world.

The interface applied fully only to twice-born men, excluding women and Shudras, and few ever completed all four stages, but it still shapes Hindu ideals of a well-ordered life.

Example 25 (UPSC 2023, 10 marks): Karma and Rebirth

Paper and question: Paper II, Q5(e)

Approach: A short note: the doctrines, textual origin, social functions and an anthropological or critical view.

Karma is the doctrine that every action produces moral consequences, and rebirth (punarjanma) holds that the soul passes through a cycle of births (samsara) shaped by past karma until liberation (moksha). Both were developed in the early Upanishads, such as the Brihadaranyaka and Chandogya, and are shared in different forms with Buddhism and Jainism.

Functions: they explain suffering and inequality as earned, motivate ethical conduct with hope of a better birth, and give continuity between generations; Max Weber called karma the most consistent theodicy ever produced (paraphrase), arguing that it stabilised the caste order.

Ethnography: Ursula Sharma (1973) found villagers in Himachal Pradesh invoking karma selectively, alongside fate, deities and witchcraft; Milton Singer's study of Madras industrialists questioned Weber's view that karma blocked enterprise.

Critics such as Ambedkar saw the doctrine as legitimising caste inequality, while many Hindus read it as a call to personal responsibility.

Example 26 (UPSC 2022, 10 marks): Dharma versus Religion

Paper and question: Paper II, Q1(c)

Approach: A short note distinguishing dharma from the Western concept of religion on meaning, scope, basis and plurality, with scholarly views.

Dharma, from the root dhri, 'to hold or sustain', means the order that upholds the cosmos and society, and the duties, law and morality that follow from it; P.V. Kane's History of Dharmashastra traces its many senses. Religion, in the Western sense, usually means belief in God or the sacred, organised as creed, worship and church.

Differences: dharma is about right conduct more than belief; it is context-bound, varying by varna, ashrama and situation (svadharma, apad dharma), while also including universal duties (sadharana dharma) such as truth and non-violence; it covers law, family, economy and ritual, not a separate sacred sphere; and it has no single founder, book or church.

Religion in the sense of sampradaya or faith tradition, Shaiva, Vaishnava, Buddhist, is narrower; thus a person's dharma can include duties to family and society regardless of sect. S. Radhakrishnan (The Hindu View of Life, 1927) presented Hinduism as a way of life rather than a creed.

Translating dharma as 'religion' therefore distorts it, as anthropologists of Indian society stress.

Example 27 (UPSC 2021, 10 marks): Purushartha and righteous living today

Paper and question: Paper II, Q1(a)

Approach: A short note: the four purusharthas and their balance, then how they can guide ethical living today, with examples and a caution.

The purusharthas are four goals of human life in Hindu thought: dharma (righteous duty), artha (wealth and power), kama (desire and pleasure) and moksha (liberation). The first three form the trivarga, with dharma regulating artha and kama, an idea found in the Mahabharata, Manusmriti and Kautilya's Arthashastra.

Relevance today: pursuing wealth and pleasure is legitimate but must be bounded by ethics, a balance relevant to corporate ethics, consumerism and corruption; dharma as duty to family, profession and society supports civic responsibility and environmental care; and moksha can be read as inner freedom and detachment that reduce stress and greed.

The scheme avoids both world-denial and hedonism, offering a holistic model of well-being, as P.H. Prabhu argued.

Its traditional form tied dharma to varna and gender, so righteous living today must reinterpret it through constitutional values of equality and dignity.

Example 28 (UPSC 2019, 10 marks): Use of doctrine of Karma and rebirth in justifying the Varna system.

Paper and question: Paper II, Q1(d)

Approach: A short note: how karma and rebirth were used to legitimise varna rank, with the textual basis, the sociological reading (Weber, Dumont) and the critiques.

The doctrine of karma and rebirth holds that one's present birth results from deeds in past lives. The Chandogya Upanishad states, in paraphrase, that those of good conduct enter a good womb, of a Brahmin, Kshatriya or Vaishya, and those of evil conduct an evil womb, directly linking rebirth to varna rank.

Justification: birth into a high or low varna was presented as earned, so inequality appeared just; doing one's svadharma faithfully, even a low one, promised a better rebirth, as the Bhagavad Gita (3.35) praises one's own duty; this discouraged revolt and encouraged acceptance.

Max Weber (The Religion of India) saw karma as the most consistent theodicy, binding people to caste duty; Louis Dumont located the system's logic in purity and pollution, with karma as supporting ideology.

Bhakti saints, Phule (Gulamgiri, 1873) and Ambedkar (Annihilation of Caste, 1936) rejected this use, and ethnography shows lower castes often contest their rank through Sanskritization rather than accept it.

Example 29 (UPSC 2018, 10 marks): Philosophy behind Purusharthas

Paper and question: Paper II, Q1(b)

Approach: A short note on the philosophy behind the purusharthas: meaning of each, their hierarchy and balance, and how they relate to the life course.

The purusharthas, 'objects of human pursuit', express a Hindu philosophy that human life has several legitimate aims which must be balanced rather than one goal pursued alone.

Dharma is the moral and social order and one's duty within it; artha is material well-being and power, treated in Kautilya's Arthashastra; kama is desire, love and aesthetic pleasure, treated in Vatsyayana's Kamasutra; and moksha is liberation from the cycle of rebirth.

The underlying philosophy is integration: the trivarga of dharma, artha and kama belongs to life in the world, with dharma as the guiding frame, while moksha is the ultimate goal; the ashramas sequence them, with the householder pursuing artha and kama and later stages turning to moksha. P.H. Prabhu saw this as a psychologically sound plan that satisfies human drives while directing them morally.

The philosophy accepts worldly life as valuable yet subordinates it to ethics and liberation, though its classical form was framed for elite men.

Example 30 (UPSC 2017, 10 marks): Varnashram and the concept of Rina.

Paper and question: Paper II, Q1(c)

Approach: A short note: varnashrama briefly, the three (or four) rinas with sources and how each is repaid at different stages, and social implications.

Varnashrama fixes duty by varna and by the four ashramas (brahmacharya, grihastha, vanaprastha, sannyasa). The concept of rina, sacred debt, tells the individual what is owed in the course of these stages.

The Taittiriya Samhita names three debts with which a Brahmin is born: rishi rina to the sages, repaid by Vedic study in brahmacharya; deva rina to the gods, repaid by sacrifice; and pitri rina to the ancestors, repaid by begetting a son and performing shraddha as a householder. The Shatapatha Brahmana adds a debt to fellow humans, repaid by hospitality.

Only after repaying these debts was a man considered free to seek moksha in the later ashramas, so rina links the life stages to obligations toward society, knowledge and lineage.

Pitri rina underlies the importance of sons, marriage as a sacrament (K.M. Kapadia) and shraddha rites such as pind-daan at Gaya, and it partly explains son preference in Indian demography.
