CLOSER

The UK is home to the world's largest and longest-running longitudinal studies.

CLOSER, the home of longitudinal research, is the interdisciplinary partnership of leading social and biomedical longitudinal population studies, the UK Data Service and The British Library. We are based at the UCL Social Research Institute (SRI).

Our mission is to increase the visibility, use and impact of longitudinal population studies, data and research to ensure that longitudinal evidence is used to address the health, social, economic and environmental challenges facing the UK, now and in the future.
