Understanding Society is a world leading study of the socio-economic circumstances and attitudes of 100,000 individuals in 40,000 British households.

It is funded by the Economic and Social Research Council (ESRC) and run by the Institute for Social and Economic Research (ISER). The study allows for deeper analysis of a wide range of sections of the population as they respond to regional, national and international change. Understanding Society will greatly enhance our insight into the pathways that influence peoples longer term occupational trajectories; their health and well-being, their financial circumstances and personal relationships.

Understanding Society also breaks new ground with its interdisciplinary focus. The study will capture biomedical data on 20,000 participants and place this alongside rich social histories, helping us weigh the extent to which people's environment influences their health.
