These follow multiple generations of people across the whole of their lives.
We survey cohort members at regular intervals, each time collecting information on the different aspects of their lives. The studies are rich resources, offering researchers a breadth and depth of data that can be used to answer a wide range of questions.
The data are free to access from the UK Data Service and some other trusted research environments.
In addition to our core studies, we work with partner organisations on the management of several affiliate cohort studies.
