1970s British Cohort Study - Life in Your Early 50s Survey

The 1970 British Cohort Study (BCS70) is following the lives of over 17,000 people born across England, Scotland and Wales in a single week of 1970.


Over the course of your lives, we have collected information on all aspects of your lives, including your health, your physical, cognitive and social development, your education and employment, and your home lives.

Thank you for your continued support of BCS70

You can find all the information you need about the study and celebrate the first 50 years of BCS70 on a dedicated website for participants.
