Our four core studies follow large, nationally representative groups of people born in a given year: the 1958 National Child Development Study, the 1970 British Cohort Study, Next Steps (born in 1990), and the Millennium Cohort Study (born in 2001). CLS is part of the UCL Social Research Institute and funded by the Economic and Social Research Council.

Alissa Goodman, Director of Centre for Longitudinal Studies, said:

“At the Centre for Longitudinal Studies we are delighted to join the UK Health Data Research Alliance. This will support our core strategy to make the social and health research data from our UK birth cohort studies as discoverable and accessible as possible to a wide research community. The Alliance plays a crucial role in promoting the visibility and use of  UK research data resources, and we are excited be part of this community and to actively collaborate in its development.” 


CLS manages the collection, curation, and dissemination of data for four major national cohort studies: the 1958 National Child Development Study (NCDS), the 1970 British Cohort Study (BCS70), Next Steps (previously known as LSYPE), and the Millennium Cohort Study (MCS). 

The majority of CLS research data is collated from questionnaires completed by the cohorts’ study members or their families at periodic study sweeps. Other specialised forms of data available for research are biomeasures, biological samples, accelerometry, genetics, geographical data, and externally linked health records and administrative records.  

Most CLS research data are available from the UK Data Service. We also disseminate some research data via other UK data sharing platforms, such as SAIL Databank, the UK Longitudinal Linkage Collaboration (UK LLC) and the European Genome-Phenome Archive (EGA). In addition, access to certain research data is governed internally by the CLS Data Access Committee (CLS DAC) because data access is subject to specialised access arrangements, such as paradata, genetic data and biological samples. To request data directly from CLS, researchers need to apply directly to the CLS DAC.
