4.2.3 - Health Inequalities by Social Class

The social gradient in health

Sociologists use the idea of health chances to show that illness and survival are socially patterned rather than randomly distributed. In the UK, people in lower social classes are more likely to experience long-term illness, disability, poor mental health, higher infant mortality and shorter lives. This is not only a gap between the very richest and the very poorest. Marmot argues that there is a gradient: as you move down the class structure, health tends to get worse at each step.

This matters sociologically because class affects income, housing, diet, work, stress, local environment and access to support. In other words, class shapes the conditions in which people are born, grow, live, work and age. Those conditions then shape health outcomes. That makes health inequality a question about stratification and power, not just biology.

Official data on mortality, infant mortality, morbidity and life expectancy repeatedly show the same pattern. Working-class and deprived groups experience more chronic illness and earlier death, while middle-class groups are more able to turn resources into healthier lives. The existence of this persistent pattern is what any explanation has to account for.

The Black Report explanations

The starting point for most answers on this topic is the Black Report (1980). It documented major class inequalities in health and set out four explanations. The report is useful because it makes clear that sociologists are not just arguing about whether inequality exists, but about why it exists.

The artefact explanation is now the least convincing. If health inequality were just a statistical illusion, we would not keep finding the same pattern across different sets of data. The social selection explanation also seems limited. Poor health can damage mobility, but it does not explain why health differences are so regular across the whole class structure.

The real debate is usually between cultural and material explanations. Cultural accounts point to lifestyle differences, but material accounts ask why those patterns exist in the first place. Working-class people do not make choices in a vacuum. Their decisions are shaped by money, stress, time, neighbourhoods and work conditions. That is why the Black Report ultimately gave most weight to the materialist explanation.

Social determinants, inequality and power

Later research largely strengthened the structural case. The Acheson Report (1998) confirmed that health inequalities had not disappeared and argued that low income, poor housing, unemployment and childhood disadvantage all mattered. It recommended reducing poverty and improving the wider conditions that shape health, especially in the early years.

Marmot (2010) took this further by arguing that health is shaped by the social determinants of health: the conditions in which people are born, grow, live, work and age. Marmot's key point is that health does not suddenly collapse only at the bottom. Instead, each step down the class hierarchy tends to bring fewer resources and worse outcomes. That makes health inequality a gradient across society, not a simple poor-versus-rich split.

Wilkinson and Pickett add a psychosocial argument. In The Spirit Level, they claim that relative inequality itself damages health by producing shame, status anxiety, insecurity and chronic stress. Even where basic survival is possible, living in a sharply unequal society can still damage physical and mental health because people compare themselves to others and experience relative deprivation.

Marxists push the argument further by locating poor health within capitalism itself. Navarro argues that capitalism produces exploitation, alienation and dangerous working conditions, while the biomedical model often individualises illness and hides its social causes. From this perspective, class-based ill health is not an accident. It is built into a system that depends on cheap labour, insecure employment and unequal access to resources.
