Since the initial birth sweep, NCDS cohort members have been followed up ten times. The latest sweep, at age 62, is now complete. Click on a sweep below to learn more about the information collected.
Data from all three waves of our survey of five national longitudinal cohort studies, including NCDS, are now available. Find out about the topics covered, response and how to access the data.
View the level of response for every major NCDS sweep and read our guidance on handling missing data.
In addition to the main NCDS sweeps there have been a number of sub studies. You can find out more about these on the following pages:

George is Professor of Population Health and Statistics at the UCL Social Research Institute and currently holds the posts of Principal Investigator of the National Child Development Study and 1970 British Cohort Study at the Centre for Longitudinal Studies. Prior to joining UCL he held posts at the London School of Hygiene and Tropical Medicine and the University of Cambridge. George is a multidisciplinary quantitative social scientist and a longitudinal population surveys methodologist. His main research interests relate to socioeconomic and demographic determinants of health over the life course and the mechanisms that underlie generational differences in health and mortality. His methodological work in longitudinal surveys focusses on applications for handling missing data, causal inference and measurement error.
Researchers investigating the links between childhood mental health and people’s later outcomes can now access a wealth of new cohort study data, originally collected more than 50 years ago.
Only children can manage the emotional and psychological demands of caring just as well as those who share duties with siblings, according to UCL researchers.
This project aims to develop a conceptual and empirical understanding of social isolation across the life course and generate comparable measures across cohorts.
