Bring out the relationship between social class and mortality.

Breaking down the question

This is a focused 20-mark question from population dynamics that asks you to bring out — that is, demonstrate and explain — the relationship between social class and mortality. Mortality is one of the three components of population growth, alongside fertility and migration, so the demographic significance of the topic is built in. But the question is sociological: it wants the class patterning of death, not a demographic recital of crude death rates.

The key idea is differential mortality — the observation that the risk of dying, and the age at which one dies, are not distributed randomly but vary systematically by social position. Social class here means the structured inequality of income, occupation, education and access to resources. The relationship to establish is the social gradient: mortality rises as one moves down the class hierarchy, so life expectancy is longer and infant deaths fewer among the privileged.

A good answer must both state this empirical regularity and explain the mechanisms behind it, since the marks lie in showing why class shapes mortality, not merely that it does.

How to approach it

Begin by defining differential mortality and asserting the central finding: an inverse relationship between social class and mortality, robust across societies and over time. Cite the classic evidence — the British Black Report and Michael Marmot's Whitehall studies, which demonstrated a continuous gradient even among employed civil servants.

Then explain the mechanisms in ordered layers: material conditions (nutrition, housing, sanitation, clean water); access to and quality of healthcare; occupational hazards and exposure; and behavioural and psychosocial factors including chronic stress. Ground the discussion in India using infant mortality rate and life expectancy differentials across class, caste and rural–urban lines, drawing on the social determinants of health framework.

Keep it tight — this is 20 marks. Reference Durkheim to show mortality has long been treated as socially patterned, and close with Amartya Sen's capability perspective and public-action argument to lift the answer beyond description.

Model answer

Mortality, though a biological event, is profoundly social in its distribution. The concept of differential mortality captures the finding that the risk and timing of death vary systematically with social position, and the most consistent pattern is an inverse relationship between social class and mortality: as one descends the ladder of income, occupation and education, mortality rises and life expectancy falls. This is the social gradient in health.

The evidence is long-standing. Britain's Black Report (1980) documented persistent class differences in death rates despite a universal health service, and Michael Marmot's Whitehall studies showed a continuous gradient among civil servants — each grade had higher mortality than the one above it, so the effect was not confined to the very poor but ran across the whole hierarchy. The relationship is thus a gradient, not merely a threshold of deprivation.

Several mechanisms explain it. Material conditions come first: the lower classes face inadequate nutrition, overcrowded and unsanitary housing, and poor access to clean water — conditions that breed infectious disease and raise infant mortality. Healthcare access compounds this, as the poor confront cost, distance and lower-quality services, and often reach treatment later. Occupational exposure matters too, since manual and informal labour carries greater physical hazard, injury and disease. Finally, behavioural and psychosocial factors — higher tobacco and alcohol use, and the chronic stress of insecurity and low control that Marmot emphasised — translate disadvantage into bodily harm.

In India the gradient is sharp and intersects with caste and region. Infant mortality and under-five mortality are markedly higher among poorer households, Scheduled Castes and Tribes, and rural populations, while life expectancy is lower. The social determinants of health framework reads these gaps as products of unequal living and working conditions rather than individual failings. Maternal mortality likewise concentrates among poor and marginalised women with least access to institutional delivery.

That death is socially patterned is not new: Durkheim showed even suicide rates vary by group integration and regulation, establishing that mortality is a social fact. Amartya Sen extends the argument, treating premature death as a failure of capabilities and arguing through his work on public action and famine that mortality reflects entitlements and the reach of public provisioning, not scarcity alone. Kerala's high life expectancy at modest income levels illustrates how public health and education can flatten the gradient.

The relationship, then, is clear and consequential. Social class governs exposure to risk, access to protection and the resources to recover, so mortality becomes a mirror of social inequality. Reducing it requires acting on the social determinants — nutrition, sanitation, education and accessible healthcare — as much as on medicine itself.

Examiner's perspective

For a 20-mark answer the examiner wants a precise, well-structured argument rather than a sprawling essay. The dividing line between average and strong scripts is whether the candidate moves from the what to the why — from stating that the poor die younger to explaining the material, healthcare, occupational and psychosocial mechanisms that produce the gradient.

Credit accrues to answers that use the concept of the social gradient explicitly and support it with recognised evidence such as the Black Report and Whitehall studies, then localise the discussion with Indian indicators — infant and maternal mortality, life expectancy differentials by class, caste and rural–urban location. Naming the social determinants of health framework signals conceptual awareness.

The strongest scripts add theoretical depth economically: Durkheim to establish mortality as a social fact and Sen to frame premature death as a capability failure answerable to public action, with Kerala as illustration. Candidates should avoid drifting into a purely medical or purely demographic treatment; the question is sociological, and the marks reward a clear demonstration that death is patterned by social structure.
