Our studies

The UCL Centre for Longitudinal Studies is home to a unique series of UK national cohort studies. Our studies follow the lives of multiple generations of people.

Each of our four core studies follows large, nationally representative groups of people born in a given year. Our oldest study charts the lives of a group of Baby Boomers born in the late 1950s, while our youngest keeps up with a group born at the turn of the new century.

In 2021, CLS also became part of the management teams for three new longitudinal studies: the Early Life Cohort Feasibility Study, Children of the 2020s, and the COVID Social Mobility & Opportunities Study. These new studies will follow groups of young people whose formative years have been shaped by the COVID-19 pandemic and other recent world events.
