The following links will take you to the relevant area of the UK Data Service for each of our four studies:
These pages contain comprehensive user guides for each dataset, data dictionaries and the list of datasets that are available for access. For any questions on our cohort data (such as how to download data or find variables), or if you have any questions about the data you have downloaded, the UK Data Service Helpdesk will be able to direct you to the experts most able to provide the answers you need.
Find the variables you need for your research project, using the CLS Excel data dictionaries. These enable you to search by variable name, research topic, questionnaire type, etc.
The UK Data Service also offers an online search platform for NCDS and BCS70 data deposited under End User Licence.
Researchers have produced a range of topic-specific guides to the content available in our studies and other UK longitudinal studies.
A guide to the cognitive measures in five British birth cohort studies (CLOSER website)
A guide to the dietary data in eight CLOSER studies (CLOSER website)
Catalogue of Mental Health Measures (standalone website)
Physical activity across age and study: a guide to data in six CLOSER studies (CLOSER website)
Information about CLS research questionnaires and variables is also searchable through CLOSER Discovery, an online platform that allows users to explore the content of multiple UK longitudinal studies.
The CLS studies documentation currently available in CLOSER Discovery covers most survey instruments, questions and variables for the the 1958 National Child Development Study, the 1970 British Cohort Study, Next Steps and the Millennium Cohort Study.
To check which data from each of our studies is included in Discovery, take a look at the content pages.
Our online bibliography includes published material based on our study data. This bibliography can help you and other researchers find out what work has already been done using our data. It also lets us know how useful the data are to the research community, which can help us to secure funding for the future of our studies.
Please do tell us about any of your work that uses our data (journal articles, books, reports, working papers, conference presentations, etc.) so that we can add it to the bibliography. You can email us at email@example.com.
