The sexual division of labour is the allocation of tasks, occupations and responsibilities to persons according to their sex. Every known society has one; what varies enormously is its content. Ploughing is men's work in much of North India and women's work in parts of South-East Asia; clerical work was a male occupation in nineteenth-century Britain and is now feminised. This variability is the central sociological finding, because it establishes that the division is social, not biological — the only task that cannot be reallocated is childbearing itself.
What makes the division a mechanism of inequality is not difference but naturalisation: the process by which a contingent allocation is presented as an expression of innate feminine nurturance or masculine strength, and therefore placed beyond argument. Ann Oakley's distinction between sex (biological) and gender (culturally constructed) was the conceptual lever that prised the two apart. Once separated, the division of labour becomes something to be explained rather than assumed.
Productive and reproductive labour
The division rests on a prior split between productive labour — activity producing goods and services for exchange, remunerated and counted in national income — and reproductive labour, the work of producing and maintaining human beings: cooking, cleaning, fetching water and fuel, nursing the sick, rearing children, caring for the aged. Reproductive labour is indispensable to production, since capital cannot function without a daily renewed labour force, yet it falls outside the wage relation and outside the boundary of what counts as "the economy". Maria Mies described this as housewifisation: the systematic redefinition of women's essential work as non-work, so that it may be appropriated without payment.
Ann Oakley's The Sociology of Housework (1974) was the first study to treat housework as an occupation — with a labour process, monotony, fragmentation and long hours — and thereby to make its invisibility and non-valuation visible. The consequence is not only unremunerated toil but exclusion from the entitlements that attach to employment: pension, provident fund, maternity benefit, the very identity of "worker".
Engels and the origin of subordination
Friedrich Engels, in The Origin of the Family, Private Property and the State (1884), offered the first materialist account. In early communal production, he argued, the household was a public affair and women's domestic work carried social standing. The domestication of animals and the accumulation of a surplus created private property; property required certainty of paternity for its transmission, which required monogamy for women; and the household turned into a private service run for the male owner. In his famous phrase, the world-historical defeat of the female sex accompanied the rise of private property. Engels thus tied gender subordination to a specific mode of production, and made the monogamous patrilineal family — rather than nature — the site of women's oppression.
Later feminists found Engels indispensable but incomplete. Heidi Hartmann (1976) objected that capital's interests alone cannot explain why men benefit; a distinct patriarchal interest in commanding women's labour is required. Marxist feminism keeps the mode of production; radical feminism keeps male interest; dual-systems theory insists both are needed.
The double burden and occupational segregation
When women enter paid employment, reproductive work is rarely redistributed. The result is the double burden — Arlie Hochschild's second shift — in which employed women return home to a further unpaid working day. Time-use evidence makes the asymmetry unmistakable: the National Statistical Office's Time Use in India 2019 survey found that women spend several hours a day on unpaid domestic and caregiving services, while the share of men participating at all in such activities is very much lower, and the gap narrows only marginally with women's employment.
In the labour market the division reappears as occupational segregation in two forms. Horizontal segregation sorts women into a narrow band of "caring" or "nimble-fingered" occupations — nursing, primary teaching, anganwadi work, garment stitching, domestic service — whose association with femininity depresses their pay. Vertical segregation confines women to the lower rungs within an occupation, producing the glass ceiling and the sticky floor: women predominate among schoolteachers but not among principals, among nurses but not among hospital administrators.
The Indian case: informality and invisibility
India shows the division in sharpened form. The overwhelming majority of women workers are in the informal sector — as agricultural labourers, home-based piece-rate workers, construction labourers, beedi rollers, domestic workers — where work is casual, unprotected and often performed inside the home, blurring the line between household and workplace and making enumeration difficult. Because much female labour is unpaid family labour on family farms and in family enterprises, successive rounds of official surveys have found female labour force participation low and, for long stretches, falling, even as female education rose. Much of that apparent decline is a measurement artefact of what the survey counts as work; much of it is real, driven by the withdrawal of women into domestic duties as household incomes rise — the status value of the secluded wife. The Self Employed Women's Association's decades of organising home-based workers exists precisely because this labour is structurally invisible.
How it sustains patriarchy
The circuit is self-reinforcing. Unpaid domestic responsibility restricts the time, mobility and skills women can bring to the labour market; weak labour market position produces low or no independent earnings; economic dependence reduces bargaining power within the household and legitimises further specialisation in domestic work. Because caring capacity is read as natural, no injustice appears to have occurred. The sexual division of labour is therefore not one patriarchal structure among others but the hinge that connects the household to the economy — which is why Walby lists both paid work and the household among her six structures.
For the UPSC answer
State early that the division is universal in existence but variable in content, and use that variability to demolish biological explanations — Oakley's sex-gender distinction is the cleanest way to do it. Build the answer around the productive-reproductive asymmetry, then evidence it with Indian material: the concentration of women in informal and home-based work, low and long-declining female labour force participation in the Periodic Labour Force Survey, and the unpaid-work gap in the Time Use Survey of 2019. Name your theorists precisely — Engels for origins, Oakley for housework, Hartmann for the dual-systems critique, Hochschild for the second shift, Mies for housewifisation. End by arguing that recognising, reducing and redistributing unpaid care work is the practical policy question that follows from the concept.
