CLS | 1970 British Cohort Study

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

What’s in the study?

Over the course of cohort members’ lives, BCS70 has collected information on health, physical, educational and social development, and economic circumstances among other factors.

BCS70 has become a vital source of evidence on key policy areas such as social mobility, education, training and employment, and economic insecurity.

What has the study found?

This invaluable study has resulted in important findings at each stage of life.

Research based on BCS70 has shown the importance of reading for pleasure for children’s cognitive development, especially in vocabulary and spelling, but also in maths.

Findings from the cohort members’ school years continue to inform the education debates of today. The study has revealed that grammar schools have been no more successful than comprehensives at helping to ensure pupils gained a university degree.

Today, research using BCS70 has shown a strong link between childhood disadvantage and adult mental wellbeing for this generation.

Who funds the study?

BCS70 is core funded by the Economic and Social Research Council. The most recent sweep, at age 46, received additional funding from the Medical Research Council and and the British Heart Foundation.

BCS70 sweeps

Since the birth survey in 1970 there have been nine ‘sweeps’ of all cohort members. The most recent sweep was at age 46. We finished surveying cohort members for this in summer 2018 and the data we have collected will be available from spring 2019 . The next sweep will take place in 2020 when cohort members are age 50.

Special features of this study

Sample design

BCS70 follows the lives of all people born in England, Scotland and Wales in one particular week in 1970. Those born in Northern Ireland were included in the birth sweep, but were not followed up in any of the subsequent sweeps.

During the birth sweep, information was collected about 16,568 babies born in England, Scotland and Wales, and a further 628 born in Northern Ireland who were not followed up subsequently. At ages 5, 10 and 16, the sample was augmented with those who had been born overseas in the relevant week and subsequently moved to Great Britain. This resulted in 68 new recruits at age 5, 286 at age 10 and 46 at 16.

Biomedical data

The Age 46 sweep is collecting extensive information on health to support biomedical and biosocial research.

It includes objective measures of anthropometry (height, weight, body fat, waist and hip circumference), blood pressure/pulse, grip strength, balance, blood samples (for analysis of cholesterol and hba1c, storage for future analyses and DNA extraction). In addition, participants are wearing an ActivPal device for 7 days to measure physical and sedentary activity and completing an online web questionnaire about their diet.

Health has been a continual focus of BCS70, but the Age 46 sweep is the first time that objective measures of health have been collected since childhood. The data collected will provide a thorough assessment of health in mid-life, and when combined with data from previous sweeps will allow for detailed examinations of the predictors of mid-life health status. Cross cohort comparisons will be possible with the 1958 National Child Development Study biomedical sweep.

Children of cohort members

The Age 34 sweep had an emphasis on parenting and children, with cohort members’ own offspring taking part in the sweep.

At age 34, a randomly allocated 1 in 2 sample of cohort members completed an additional interview module and a paper self-completion questionnaire about each of their children.

Cohort members’ children aged over 10 also completed their own questionnaires and a series of cognitive assessments, which allows for the study of transfer of ability from one generation to the next.
