BCS70 Birth survey (1970)
The first BCS70 survey took place in 1970 and was conducted by the Department of Child Health and the National Birthday Trust Fund.
17,198 cohort members took part in total.
This sweep consisted of:
A form which was filled out by the midwife
A 3 part questionnaire (Part I was normally completed by the midwife in an interview with the mother shortly after the birth. Part II was completed from the records and from personal experience. Part III related to the first seven days after the birth, some portions being filled in as a diary. For multiple births separate forms were completed for each child).
More information about the coverage of each element of the survey and the downloadable questionnaires are provided here.
The data are available from the UK Data Service. Guidance on how to use the data is provided here.
Fieldwork was funded by the Medical Research Council, National Birthday Trust Fund, Department of Health and Social Security and Royal College of Obstetricians and Gynaecologists.
