Caste in India: the birth-ascribed order that refuses to die

No institution explains India, and embarrasses it, quite like caste. It is the one social order where your birth certificate once decided your occupation, your marriage pool, whom you could share a meal with, and how close you could come to a temple. Ambedkar's verdict still stings: caste is not merely a division of labour, it is a division of labourers. This article maps how the system works, how sociologists explained it, and the exam's favourite question, whether modern India is finally outgrowing it.

What caste is: the birth-ascribed order

Caste is, in the standard textbook definition, 'a hereditary, endogamous group with a common name, occupation, culture, mobility, and status, relatively rigid in matters of mobility, the distinctiveness of status, and forming a single homogenous community'. Three words in it are load-bearing: hereditary, endogamous and relatively rigid mobility, which is why caste outlives the occupations it was once tied to.

Untouchability is 'the act of isolating a group from the majority due to social customs that considered untouchables to be impure and polluted'. It is the sharpest edge of the caste order, abolished by Article 17 and made punishable by the Protection of Civil Rights Act, 1955.

Caste is a system of endogamous groups recruited by birth, with hereditary membership that determines behaviour, obligations and social evaluation. Gandhi once credited the caste system with holding Hindu society together; Marx called the castes "the most decisive impediment to India's progress and power." Both reactions point at the same machinery, a social order that allocates dignity before it allocates work.

The machinery runs on a few unmistakable features. Hierarchy grades groups from high to low; ascription by birth fixes membership at birth with no exit; endogamy confines marriage within the group; occupational fixity links caste to traditional work; purity and pollution beliefs justify segregation and control interaction, who eats with whom, who enters whose house; and the whole order is policed by community pressure, historically through caste panchayats, today also through matrimonial apps with caste filters. A further feature completes the classic list: segmental division of society, meaning each caste is itself divided into sub-castes and segments, so the system is a hierarchy of hierarchies.

Varna and jati: the idea and the reality

Two terms must never be confused. Varna is 'the four-fold division of society into Brahmana, Kshatriya, Vaishya and Shudra', while Jati is 'a generic term referring to species'. Varna is the textual scheme; jati is the lived reality of thousands of endogamous groups, and UPSC traps candidates who interchange them.

UPSC repeatedly tests whether aspirants can separate the textual ideal from the lived reality. The varna scheme is a fourfold philosophical classification found in Vedic texts and the Manusmriti; jati is the thousands-strong, regionally varied, endogamous reality in which Indians actually live.

Varna, the textual ideal

• Four categories: Brahmin, Kshatriya, Vaishya, Shudra, rooted in Vedic texts and the Bhagavad Gita's guna-karma logic.
• Theoretically flexible: status could shift with learning and conduct; presented as a harmonious division of labour.
• Does not formally include Dalits/Avarnas within its four categories.

Jati, the social reality

• Over 3,000 jatis and sub-castes with regional and occupational variation, local, practical, socially enforced.
• Rigid and hereditary: membership is by birth, marriage is endogamous, status cannot change within a lifetime.
• Institutionalises untouchability and exclusion, the feature the varna ideal never formally contains.

Where did caste come from? Four theories of origin

Before asking what caste does, UPSC expects you to know where scholars think it came from. Four classical theories compete, and each anchors to a name and a text.

• Divine theory: the Purusha Sukta of the Rig Veda describes the cosmic being Purusha sacrificed to create the four varnas, the Brahmin from his mouth, the Kshatriya from his arms, the Vaishya from his thighs and the Shudra from his feet. It is the textual-religious sanction of hierarchy, not a historical explanation, but it supplied the ideology.
• Racial theory: Herbert Risley argued that caste arose from the contact and conflict between Aryan and Dravidian races, with endogamy enforced to preserve racial purity. Modern scholarship has discredited the racial frame, but the theory matters because colonial ethnography used it to harden caste categories.
• Occupational theory: Nesfield held that function is the basis of caste, that occupational guilds gradually hardened into hereditary castes. It explains the tight caste-occupation link visible in the jajmani system but not the ritual hierarchy built on top of it.
• Political theory: Ibbetson (and, in the guild version, Abbe Dubois) argued that caste was a Brahminical political device to preserve priestly dominance, with the priestly class organising society to secure its own supremacy.

No single theory survives scrutiny alone; the exam rewards the synthesis: religious sanction (divine), social closure (racial and endogamy), economic function (occupational) and power (political) combined to produce the system.

How sociologists explained caste

Caste has been read through almost every major sociological lens, and the examiner loves asking which thinker said what.

• G.S. Ghurye and M.N. Srinivas (functionalism): caste as a system of social organisation that allocates roles and maintains order, visible in the jajmani system of hereditary, ritualised exchange between castes.
• Louis Dumont (structural-functionalism): in Homo Hierarchicus, caste is a hierarchy of purity and pollution, not of wealth, status is religious, not economic.
• Karl Marx and D.D. Kosambi (Marxism): caste as a mechanism of economic exploitation and labour control.
• Max Weber: caste as a status group, endogamy preserves status boundaries, which are distinct from mere class.
• M.N. Srinivas (Sanskritisation and dominant caste): lower castes climb by adopting upper-caste rituals, while real local power flows from the dominant caste, numbers, land and political clout, not ritual rank (think Jats in Haryana, Marathas in Maharashtra).
• B.R. Ambedkar (subaltern perspective): caste as graded inequality, a human institution, not a divine one, that denies dignity and can therefore be changed by human effort.

Annihilation of Caste (1936) is Ambedkar's undelivered speech turned into a text, and the sharpest statement of the subaltern view: caste is a system of graded inequality, a human institution rather than a divine order, and Hindu society cannot be reformed without annihilating caste itself. Quote it whenever a question asks for the radical position.

The Dravidian strand of the anti-caste story belongs to E.V. Ramasamy "Periyar", whose Self-Respect Movement in Tamil Nadu attacked Brahminical dominance, priestcraft and the religious sanction of hierarchy, promoting rationalism, women's rights and inter-caste equality. Periyar supplies the southern anchor that the Ambedkar-Phule-Gandhi triad alone cannot.

Why caste refuses to disappear

M.N. Srinivas's Sanskritization is the key mobility channel: 'Low castes attempt to raise their social status by adopting the rituals and practices of higher castes, such as vegetarianism and teetotalism, to claim a higher position in the caste hierarchy'. It is mobility that leaves the hierarchy intact.

Its counterpart is Westernization, the adoption of Western patterns in technology, institutions, dress and values, which corroded the ritual justification of hierarchy. Two more terms complete the vocabulary: a dominant caste is one that wields preponderant economic and political power in a locality even without top ritual rank, and the jajmani system is 'the exchange of goods and services, with each jati contributing its share based on occupational speciality', the old village economy that bound castes in mutual dependence.

The Constitution abolished untouchability (Article 17) and outlawed caste discrimination; seven decades later, caste is everywhere, in marriage advertisements, campus politics, and electoral arithmetic. The persistence has structural reasons.

• Endogamy: the single strongest preserver of caste boundaries. Recent IHDS rounds show only about 5% of marriages are inter-caste; marriage within the group reproduces the group.
• Political mobilisation: parties organise caste blocs for electoral gain, so democracy has often reinforced caste identity rather than dissolving it, Rajni Kothari's classic argument.
• Digital reinforcement: matrimonial websites keep caste as a search filter; social media lets caste networks reassemble online.
• Economic inheritance: historical deprivation compounds, IHDS data shows nearly 60% of Dalit households are landless agricultural labourers against 25% of forward castes, and over 90% of manual scavengers are Dalits.
• Institutional apathy: strong laws like the SC/ST (Prevention of Atrocities) Act, 1989 coexist with underreporting and weak prosecution; a 2024 JNU study even found rental and job discrimination against Dalits in Delhi and Mumbai.

Cross-reference: the historical struggle against caste, Phule's Satyashodhak movement, Ambedkar's campaigns, the temple-entry movements, is covered in detail in modern-32-caste-social-movements. This article's concern is the system as a living contemporary order.

Rural and urban caste: two different animals

The 2026 mains paper asked point-blank: "Is caste disappearing in urban India?" The honest answer is that caste has changed shape rather than vanished, and the rural-urban contrast is the evidence.

Rural caste system

• Rigid and traditional; birth-based hierarchy dominates status and daily interaction.
• Strong caste-occupation linkage; the jajmani pattern of exchange still visible in pockets.
• Purity-pollution rules actively practised; caste panchayats retain social-control power.
• Discrimination is open and visible, separate wells, temple-entry conflicts, honour violence.

Urban caste system

• Relatively flexible: education, income and profession increasingly compete with birth for status.
• Occupational mobility is common; market relations replace hereditary exchange.
• Ritual exclusion is diluted or symbolic, but reappears subtly: housing segregation, "gated community" apartheid, rental bias.
• Caste survives as identity politics and endogamy rather than as ritual order, modernised, not dead.

The costs of caste: what the data says

Arguments about caste must be anchored in evidence. The record is sobering: NCRB 2022 data (as reported) showed crimes against Scheduled Castes rising 13.1% and against Scheduled Tribes 14.3%, with Uttar Pradesh and Rajasthan topping the list. Manual scavenging, over 90% Dalit, still kills: reports counted over 400 sewer and septic-tank deaths between 2018 and 2023.

• Political: SC/ST communities remain underrepresented in leadership and bureaucracy; vote-bank fragmentation deepens sectionalism.
• Economic: Dalits and OBCs are overrepresented in informal work and underrepresented in white-collar sectors; a 2024 study linked caste discrimination to anxiety and depression among Dalit youth.
• Social: educational attrition from institutional bias, intersectional violence against Dalit women (the Hathras case, 2020, is emblematic), and the persistence of honour killings against inter-caste couples in states like Haryana.

The livest policy question is the caste census: the 2027 Census will enumerate castes for the first time since 1931. Supporters argue that only counted disadvantage can be precisely targeted, making quotas evidence-based; critics warn that counting caste hardens the very identities the Constitution hoped would fade, and that the data will be weaponised electorally. UPSC will expect both sides, not a verdict.

Way forward

Eradicating caste needs more than outlawing it, it needs rewiring the incentives that reproduce it. Concrete directions: enforce anti-atrocity law with caste-sensitivity training in police and judicial academies; attack endogamy through the Dr. Ambedkar inter-caste marriage incentive and guidelines removing caste filters from matrimonial platforms; build Dalit capital via Stand-Up India and the Dalit Indian Chamber of Commerce and Industry (DICCI), which reports over 5,000 Dalit-owned enterprises; and measure the problem, a National Caste Discrimination Index tracking housing segregation, atrocity rates and inter-caste marriage data would make an invisible hierarchy visible.

Key Terms

• endogamous groups recruited by birth: Endogamous groups recruited by birth are communities, such as castes, whose membership is acquired solely by being born into them, with marriage restricted to fellow members. Endogamy preserves group boundaries, purity norms, and hereditary occupational roles across generations. This sociological definition captures how jati-based stratification reproduces itself without any element of individual choice. For UPSC, it matters in GS1 Indian society questions on caste, social stratification, and the persistence of endogamous practices despite modernisation. The jati system in India, in which marriage is conventionally arranged within the same caste
• Gandhi: Gandhi is the honorific for Mohandas Karamchand Gandhi (1869-1948), leader of India's national movement and apostle of non-violence. He forged satyagraha, truth-based non-violent resistance, into a mass political method through campaigns like Non-Cooperation, Civil Disobedience and Quit India, while preaching swadeshi, trusteeship and village self-rule. For UPSC, he anchors GS-1 modern Indian history and GS-4 ethics, where his life is the canonical case study in moral leadership. The Dandi March of March-April 1930, when Gandhi led the Salt Satyagraha against the British salt tax.
• Hierarchy: Hierarchy is the ranking of persons, offices or groups by levels of authority, status or sanctity, so that each level is subordinate to the one above it. The term recurs across UPSC topics: Weber's bureaucratic hierarchy, the caste hierarchy in Indian society, the hierarchy of courts, and hierarchies of needs in ethics answers. It is worth mastering because it links governance, society and organisation-theory questions.
• ascription by birth: Ascription by birth is the sociological principle that a person's social status is assigned at birth rather than earned through effort or achievement, a classic example being the Indian caste system. It contrasts with achieved status in modern meritocratic societies. For UPSC it underpins GS-1 questions on social stratification, caste, gender roles and mobility, and GS-4 discussions on fairness. the caste system in India
• endogamy: Endogamy is the practice of marrying within a defined social group, such as a caste, sub-caste, or tribe. Caste endogamy in India is the mechanism that has preserved the jati system across generations, enforced by social sanction and family pressure. It matters for GS-1 society questions on social stratification, kinship, and the persistence of caste. The traditional norm in Hindu society of arranged marriage within one's own jati, which sociologists identify as the key institution reproducing caste boundaries.
• occupational fixity: Occupational fixity is the hereditary linkage of work to birth in the traditional caste order, where a person's occupation was largely determined by jati rather than aptitude or choice. It restricted mobility, transmitted skills within kin groups and underpinned the jajmani exchange of services in village India. For GS-1 society it is key to questions on the features of the caste system and how modernisation, education and urbanisation have loosened it. Under the jajmani system, service castes performed hereditary occupational roles for landowning families in return for customary payments.
• purity and pollution: Purity and pollution are the ritual concepts underpinning the caste hierarchy: occupations and groups are ranked by their supposed ritual purity, with 'polluting' contact through touch, food, or marriage requiring purification. Louis Dumont made this hierarchy central to his analysis of caste. UPSC significance: GS-1, Indian society and social stratification.
• segmental division of society: Segmental division of society is G. S. Ghurye's term for the caste system's division of society into closed, birth-based segments in his book Caste and Race in India (1932). It is the first of his six features of caste, alongside hierarchy, endogamy and restrictions on occupation and social intercourse. For UPSC GS-1 and the sociology optional it is the starting definition for questions on the structure of the caste system and social stratification.
• jati: Jati is the endogamous, birth-based community group that forms the operative unit of the Indian caste order. There are thousands of jatis, ranked by notions of purity and pollution, governing marriage, occupation, and ritual life, and they are distinct from the fourfold varna scheme of the texts. UPSC significance: GS-1 society (social stratification) and GS-2 questions on reservation and social justice.
• Divine theory: the Purusha Sukta of the Rig Veda describes the cosmic being Purusha sacrificed to create the four varnas, the Brahmin from his mouth, the Kshatriya from his arms, the Vaishya from his thighs and the Shudra from his feet. It is the textual-religious sanction of hierarchy, not a historical explanation, but it supplied the ideology.
• Purusha Sukta: The Purusha Sukta is the celebrated cosmogonic hymn Rigveda 10.90 describing the primeval cosmic being (Purusha), whose self-sacrifice creates the universe. From his body emerge the moon, sun, gods and the four varnas: the Brahmin from the mouth, the Kshatriya from the arms, the Vaishya from the thighs and the Shudra from the feet. It is UPSC-significant as the earliest textual source for the varna system and Vedic cosmology. Cited in debates on the textual origins of caste in ancient Indian society.
• Racial theory: Racial theory is the colonial-era explanation of the caste system associated with Herbert Risley, the 1901 Census Commissioner, who argued that caste originated in racial differences between Aryans and non-Aryans and used the nasal index to classify population groups. Later anthropologists rejected it, showing caste as a social and occupational hierarchy rather than a biological one. It matters for UPSC in GS-1 society questions, where competing theories of caste origin are a standard mains topic for sociology-adjacent answers. Herbert Risley, Census Commissioner for the 1901 Census
• Herbert Risley: Herbert Risley was a British colonial administrator and anthropologist, Census Commissioner for the 1901 Census of India. He promoted the racial classification of castes using the "nasal index" and argued that caste had a racial basis. For UPSC, he exemplifies colonial ethnography and the census as an instrument of rule. The 1901 Census, the first to classify the population by caste on Risley's scheme.
• Occupational theory: The occupational theory of the origin of caste, associated with John Nesfield, holds that caste arose from the functional division of labour: function and function alone is responsible for the origin of caste. Occupations practised by a group hardened into hereditary castes, with nobler occupations ranked higher. It matters for UPSC sociology and ancient-history prelims, where it is tested against rival theories such as Risley's racial theory and the traditional divine-origin theory. John Nesfield's formulation that 'function and function alone' created the caste structure
• Nesfield: Nesfield is John Collinson Nesfield (1836-1919), the British educator who served in India as professor, school inspector and Director of Public Instruction in Oudh and the North-Western Provinces. His widely used textbooks, including English Grammar: Past and Present, shaped English teaching in colonial India, and his census-linked study of caste argued for its fluid, occupational basis. For UPSC he matters for colonial education history and early sociological writing on caste. his textbook English Grammar: Past and Present
• Political theory: Ibbetson (and, in the guild version, Abbe Dubois) argued that caste was a Brahminical political device to preserve priestly dominance, with the priestly class organising society to secure its own supremacy.
• Ibbetson: Sir Denzil Ibbetson (1847-1908) is a British ICS officer remembered as a pioneering colonial ethnographer of Punjab. As superintendent of the 1881 Punjab census, he produced a celebrated report (1883) on the races, castes and tribes of the province, reprinted as 'Panjab Castes' in 1916. His writings matter for UPSC because they exemplify how colonial ethnography and the census hardened caste categories in British India.
• G.S. Ghurye and M.N. Srinivas (functionalism: G.S. Ghurye and M.N. Srinivas were pioneering Indian sociologists associated with the functionalist study of Indian society. Ghurye applied an Indological functionalism to caste and kinship, while Srinivas used structural-functional fieldwork, developing concepts like Sanskritisation, westernisation and the dominant caste from his Rampura village study. For UPSC, they represent the two foundational approaches, textual and field-based, of Indian sociology.
• Louis Dumont (structural-functionalism: Louis Dumont's structural-functionalism is the French sociologist's theory of Indian caste developed in Homo Hierarchicus (1966). He argued that caste is organised by a single principle of hierarchy based on the pure-impure opposition, with ritual status separated from political power. It is a staple of UPSC sociology and GS-1 society answers on caste, hierarchy and the Dumont versus Srinivas debate. Homo Hierarchicus (1966)
• Karl Marx and D.D. Kosambi (Marxism: The pairing of Karl Marx and D.D. Kosambi refers to Kosambi's application of Marxist historical materialism to ancient India. In An Introduction to the Study of Indian History (1956), the mathematician-turned-historian analysed Indian society through modes of production, class, and the transition from tribe to state, founding a materialist school of Indian historiography. For UPSC, Kosambi is the key name in historiography questions and mains answers on interpreting ancient India. Kosambi's An Introduction to the Study of Indian History (1956).
• Max Weber: Max Weber (1864 to 1920) was a German sociologist whose ideal-type theory of bureaucracy, built on hierarchy, fixed rules, impersonality, and merit recruitment, became the model of modern administration. He distinguished traditional, charismatic, and rational-legal authority, and in The Protestant Ethic and the Spirit of Capitalism linked religious values to economic behaviour. For UPSC his ideas frame GS-4 debates on bureaucratic ethics, neutrality, and reform. India's civil services, with rule-bound procedure and merit-based recruitment, are routinely analysed as a Weberian rational-legal bureaucracy.
• M.N. Srinivas (Sanskritisation and dominant caste: M.N. Srinivas's Sanskritisation and dominant caste are his twin concepts explaining social mobility in India: lower castes emulate the rituals of upper castes to rise in status, while a numerically and economically powerful caste dominates village life. They remain the standard UPSC framework for mains answers on caste mobility, hierarchy and change in rural India. Fieldwork in Rampura village, Mysore (1940s-50s)
• dominant caste: Dominant caste is a concept coined by the sociologist M. N. Srinivas to describe a caste that wields preponderant power in a village or region through numerical strength, land ownership, economic resources and political influence, regardless of its ritual rank in the hierarchy. For UPSC, it is a GS-1 society keyword for analysing rural power structures, agrarian politics and the social base of reservations.
• B.R. Ambedkar (subaltern perspective: The subaltern perspective on B.R. Ambedkar reads him as the foundational voice of India's Dalit standpoint from below. He theorized caste as graded inequality, indicted the Hindu social order in Annihilation of Caste (1936), and treated constitutional morality, representation, and separate political organization as tools of emancipation. For UPSC, this lens contrasts with elite-nationalist historiography and grounds GS-1 answers on caste and social empowerment. His burning of the Manusmriti at Mahad in December 1927 symbolized the subaltern rejection of scriptural sanction for caste.
• graded inequality: Graded inequality is B.R. Ambedkar's concept that the caste system is not simple inequality but a hierarchy of ascending and descending grades, in which each caste has someone below it to look down upon. This structure prevents unified resistance, since every group is simultaneously oppressed and oppressor. It comes from Annihilation of Caste and is central to GS-1 society and GS-4 thinkers.
• Annihilation of Caste: Annihilation of Caste is B.R. Ambedkar's 1936 text, originally an undelivered presidential address for the Jat-Pat-Todak Mandal's Lahore conference. When the Mandal asked him to delete passages criticising Hindu scriptures, Ambedkar refused and published the speech himself, arguing that caste could not be reformed without destroying its religious sanction. For UPSC, it is the foundational critique of caste and a staple of social-justice answers. Gandhi replied to it in Harijan in 1936, beginning the famous Ambedkar-Gandhi debate on whether caste could be reformed from within.
• E.V. Ramasamy "Periyar: E.V. Ramasamy Naicker (1879 to 1973), honoured as Periyar, meaning the great elder, was the Tamil social reformer who led the Self-Respect Movement from 1925 against caste hierarchy and Brahminical dominance. He founded the Dravidar Kazhagam, championed rationalism and women's rights, and joined the Vaikom Satyagraha of 1924. For UPSC, he is the key figure of the non-Brahmin and Dravidian movements in modern Indian history. The Vaikom Satyagraha of 1924, in which he participated.
• Self-Respect Movement: The Self-Respect Movement was a Tamil social reform movement launched by E.V. Ramasamy 'Periyar' in 1925. Rejecting Brahminical dominance, caste hierarchy and ritualism, it promoted rationalism, women's rights, inter-caste marriage and self-respect marriages without priests. It became the ideological root of the Dravidian movement and parties like the DMK. For UPSC, it is essential GS-1 modern history: social reform, anti-caste mobilisation and Tamil Nadu's political evolution. Founded by Periyar E.V. Ramasamy in Tamil Nadu in 1925
• endogamy: Endogamy is the practice of marrying within a defined social group, such as a caste, sub-caste, or tribe. Caste endogamy in India is the mechanism that has preserved the jati system across generations, enforced by social sanction and family pressure. It matters for GS-1 society questions on social stratification, kinship, and the persistence of caste. The traditional norm in Hindu society of arranged marriage within one's own jati, which sociologists identify as the key institution reproducing caste boundaries.
• Political mobilisation: Political mobilisation is the process of activating citizens, groups, or communities for collective political action, through parties, movements, campaigns, or social media. It converts grievances into organised pressure on the state. For UPSC it matters in GS-2 (pressure groups, electoral politics) and modern history, where mass mobilisation distinguished Gandhian movements from earlier elite petitioning. The 1919 Rowlatt satyagraha mobilised all-India protest against British repression.
• Rajni Kothari: Rajni Kothari is the political scientist (1928-2015) who founded the Centre for the Study of Developing Societies (CSDS) in New Delhi in 1963 and wrote Politics in India (1970), the landmark study of the Congress system and one-party dominance. His concepts of the Congress system, party dominance and the criminalisation of politics shaped how Indian democracy is studied. Mains-relevant for questions on post-independence politics and party systems. the founding of CSDS in 1963
• Digital reinforcement: matrimonial websites keep caste as a search filter; social media lets caste networks reassemble online.
• Economic inheritance: historical deprivation compounds; IHDS data shows nearly 60% of Dalit households are landless agricultural labourers against 25% of forward castes, and over 90% of manual scavengers are Dalits.
• Institutional apathy: Institutional apathy is the persistent indifference of public institutions toward the problems they exist to solve, visible in delayed justice, unimplemented schemes, and unresponsive administration. It is frequently cited in GS-4 ethics and GS-2 governance answers as a structural cause of poor service delivery. For UPSC it is a useful analytical frame for questions on administrative reform.
• modern-32-caste-social-movements: Caste-based social movements in modern India were organised struggles against caste hierarchy, untouchability and Brahminical dominance from the nineteenth century onward. Led by reformers and lower-caste associations, they demanded temple entry, education and political representation, and fed into the anti-untouchability and reservation debates. They are central to GS-1 modern history on social reform and the making of modern Indian society. Jyotiba Phule's Satyashodhak Samaj, founded in 1873.
• Political: In UPSC usage, 'political' means relating to the exercise of power, governance, and public affairs, whether in constitutional design, electoral competition, or international relations. It appears in phrases like political theory, political geography, and political economy that frame how states are organised and how decisions are made. It matters for UPSC because much of GS-2 and the polity syllabus is the structured study of political institutions and processes.
• Economic: In UPSC usage, economic describes anything relating to the production, distribution and consumption of goods and services, such as policy, growth, trade and livelihoods. In GS Paper III and the economy section of prelims, the term anchors questions on inflation, fiscal policy, agriculture and industry. Answers should tie the economic dimension to concrete data or policy.
• Social: In the UPSC context, 'social' refers to the collective life of society and its welfare, as in the constitutional goal of 'social, economic and political justice' in the Preamble. It appears across the syllabus: social justice under Article 38, social empowerment, social sector schemes, and social capital. For UPSC, the word signals questions on welfare policy, inclusion, and the state's duty to secure a social order founded on justice.
• caste census: A caste census is the enumeration of India's population by caste, last done comprehensively in 1931 and excluded from censuses since independence. The Socio-Economic and Caste Census of 2011 collected caste data but never released it, and demands for a fresh caste census now centre on rationalising reservation policy. For UPSC, it is a live GS2 polity debate on data, equity and affirmative action. Bihar's 2023 caste survey, published by the state government, which reported OBCs and EBCs at about 63 per cent of its population.
• enforce anti-atrocity law: Enforce anti-atrocity law is the demand or administrative duty to make the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989, effective in practice rather than on paper. Enforcement depends on prompt FIR registration, investigation by senior officers, special courts, witness protection, and relief and rehabilitation for victims. Gaps between the statute and ground reality make enforcement itself a justice issue. For UPSC, it matters in GS2 social justice and prelims questions on protective legislation for SCs and STs. The Scheduled Castes and the Scheduled Tribes (Prevention of Atrocities) Act, 1989
• attack endogamy: Attack endogamy is B. R. Ambedkar's prescription in Annihilation of Caste for destroying the caste system: since endogamy, the practice of marrying strictly within one's caste, is the mechanism that sustains caste, reform must attack it through inter-caste marriage and inter-dining. It is a landmark GS-1 social-issue concept and a favourite mains quote on caste reform and social justice. Annihilation of Caste (1936)
• build Dalit capital: This phrase refers to building economic capital among Dalits through entrepreneurship, asset ownership, credit access, and business networks, so that economic power complements political and social empowerment. It matters for UPSC because inclusive growth, social justice, and schemes for SC entrepreneurs are frequent GS-2 and GS-3 themes. It reflects the shift from welfare alone to enterprise-led empowerment. The Dalit Indian Chamber of Commerce and Industry (DICCI), founded in 2005 by Milind Kamble
• measure the problem: 'Measure the problem' is a governance maxim: a policy issue must be quantified with data and indicators before interventions are designed, so that targets, budgets, and outcomes can be tracked. It underpins evidence-based policymaking and programme evaluation. It matters for GS-2 governance and GS-3 inclusive growth questions on data-driven administration. NITI Aayog's National Multidimensional Poverty Index, which measures deprivation across health, education, and living standards to guide anti-poverty policy.
• caste: Caste is 'a hereditary, endogamous group with a common name, occupation, culture, mobility, and status, relatively rigid in matters of mobility, the distinctiveness of status, and forming a single homogenous community'. The load-bearing words are hereditary, endogamous and relatively rigid mobility.
• varna: Varna is 'the four-fold division of society into Brahmana, Kshatriya, Vaishya and Shudra', while Jati is 'a generic term referring to species'. Varna is the textual scheme; jati is the lived reality of thousands of endogamous groups.
• untouchability: Untouchability is 'the act of isolating a group from the majority due to social customs that considered untouchables to be impure and polluted'. Abolished by Article 17 and punishable under the Protection of Civil Rights Act, 1955, it is the sharpest edge of the caste order.
• Sanskritization: Sanskritization is M.N. Srinivas's concept: 'Low castes attempt to raise their social status by adopting the rituals and practices of higher castes, such as vegetarianism and teetotalism, to claim a higher position in the caste hierarchy'. It is mobility that leaves the hierarchy intact.
• Westernization: Westernization is M.N. Srinivas's concept of social change through the adoption of Western patterns in technology, institutions, dress and values. Unlike Sanskritization it corrodes the ritual ideology that justifies hierarchy rather than working within it.
• jajmani system: The jajmani system is 'the exchange of goods and services, with each jati contributing its share based on occupational speciality', the old village economy of mutual dependence between castes. It matters for GS-1 as the economic base of the traditional caste order.
