Longitudinal studies track the same people throughout their lives, helping us understand how life in the UK is changing. CLOSER's mission is to maximise their use to help improve our understanding of key social and medical challenges - including how best to combat life threatening diseases, reduce obesity and improve social mobility and life chances.

CLOSER is a partnership of eight UK longitudinal studies, the British Library and the UK Data Service.

New intergenerational study

The Hertfordshire Cohort Study (HCS) comprises a nationally unique study of 3,000 men and women born during 1931-1939 and still resident in the English county of Hertfordshire during the 1990s.

HCS has recently been given permission to start work on an intergenerational study: the Hertfordshire 3G study aims to collect health and lifestyle information from three generations of the same family (namely the original HCS participant and any of their children or grandchildren).
