Health inequalities

What are health inequalities?

Health inequalities are preventable and unjust differences in health status experienced by certain population groups. People in lower socio-economic groups are more likely to experience chronic ill-health and die earlier than those who are more advantaged. Health inequalities are not only apparent between people of different socio-economic groups – they exist between different genders and different ethnic groups1.

Health inequalities are often observed along a social gradient. This means that the more favourable your social circumstances such as income or education, the better your chance of enjoying good health and a longer life. While there is a significant gap between the wealthy and the poor, the relationship between social circumstances in health is in fact a graded one.

What causes health inequalities?

"Inequalities in health arise because of inequalities in society – in the conditions in which people are born, grow, live, work and age"    

Sir Michael Marmot, 2010

The causes of health inequality are complex but they do not arise by chance.  The social, economic and environmental conditions in which we live strongly influence health. These conditions are known as the social determinants of health, and are largely the results of public policy.

Cross sectoral work on the social determinants of health

IPH has set out cross sectoral work on the social determinants of health as a key area of action within it's Corporate Plan 2010-2013. Working closely with others, IPH aims to create greater awareness among the health sector, government agencies and the public of the importance of social determinants of health. This is in line with broad public health approach advocated in Northern Ireland's Investing for Health strategy and the Republic of Ireland's Strategy Quality and Fairness.
