More than 17,000 people have taken part in BCS70 since it started.
As you were growing up, your parents or guardians will also have taken part in the study as well. During your time at school information was also collected from your teachers. In 2004, when you were 34, we asked your children (if you had any at this time) to complete a questionnaire and a number of assessments. You can learn more about who we’ve spoken to on the ‘Survey’ pages.
In 2012, when you were 42, we asked your partners (and you) to give us permission to add information from health records held by the NHS and economic records held by the Department of Work and Pensions (DWP) and Her Majesty’s Revenue and Customs (HMRC) to the information you have given us in our surveys over the years.
