1970 British Cohort Study
The 1970 British Cohort Study (BCS70) is a continuing, multi-disciplinary longitudinal survey monitoring the development of babies born in the UK during the week of 5–11 April 1970.
The first wave in 1970, called the British Births Survey, was conducted by the National Birthday Trust Fund together with the Royal College of Obstetricians and Gynaecologists in order to collect information to compare with those of the National Child Development Study (NCDS). The following two sweeps in 1975 and 1980, when the study was known as the Child Health and Education Study (CHES), were carried out by the Department of Child Health at Bristol University. The 1986 survey was conducted by the International Centre for Child Studies and called Youthscan which was then taken over for the following surveys by the Social Statistics Research Unit (SSRU), now known as the Centre for Longitudinal Studies (CLS). By 2016 there were 770 papers and books published about the 1970 British Cohort Study.
The scope of the BCS70 has been broadened in the course of the different surveys. While the focus was on medical aspects at birth, factors such as physical, educational, social and economic development were subsequently taken into account.
Methodology and scope
The primary method of data collection consists of face-to-face interviews (with the parents), self-completion questionnaires and psychological and educational measurements. The sample size included 17,287 babies in England, Scotland, Wales and Northern Ireland born in 1970.
The findings from the BCS70 have generated over 770 publications, a list of which can be found here. One key publication which also includes data of other British Cohort Studies is Elsa Ferri, John Bynner and Michael Wadsworth (eds.)(2003) Changing Britain, Changing Lives: three generations at the turn of the century
