Our online bibliography is an excellent resource for finding publications based on data from the NCDS as well as our other three studies. It includes over 5,000 publications and is searchable by study, year, author, journal name, title and abstract.
The 1958 National Child Development Study (NCDS) is following the lives of an initial 17,415 people born in England, Scotland and Wales in a single week of 1958. It started in 1958 at birth, as the Perinatal Mortality Survey.
What’s in the study?
Over the course of cohort members’ lives, we have collected information on their physical and educational development, economic circumstances, employment, family life, health behaviour, wellbeing, social participation and attitudes.
The study has become an invaluable data source on such topics as the effects of socioeconomic circumstances, and child adversities on health, and social mobility. It has also become an important resource for the study of genetics.
What has the study found?
This study has made influential discoveries about every stage of life. Research has uncovered the wide-reaching negative effects of mothers’ smoking during pregnancy. It has shown how mental health problems develop across childhood and into adult life. It has revealed how economic inequalities are transmitted across generations, and the origins in childhood of health inequalities in middle age. Government, doctors, teachers, charities and others have used findings to develop services and policies that help improve people’s lives.
Today the 1958 cohort is one of the best resources in Britain for understanding the lifelong factors affecting retirement and ageing.
Who funds the study?
NCDS receives core funding from the Economic and Social Research Council. The next NCDS sweep, at age 62, is co-funded by the Medical Research Council, the US National Institutes of Health and the Department for Work and Pensions.
Since the initial birth sweep, NCDS cohort members have been followed up ten times. The next sweep will take place in 2020 – 2021 when the cohort members will be in their early sixties. Click on a sweep below to learn more about the information collected.
Data from Waves 1 and 2 of our survey of five national longitudinal cohort studies, including NCDS, are now available. Find out about the topics covered, response and how to access the data.

In addition to the main NCDS sweeps there have been a number of sub studies. You can find out more about these on the following pages:
This commemorative book tells the story of one of the longest running and most important studies of its kind in the world.
Information from the NHS about cohort members’ health care and treatment in hospitals has now been linked to two longitudinal cohort studies, which have collected survey data over six decades – the 1958 National Child Development Study (NCDS) and the 1970 British Cohort Study (BCS70)…
This provides information about the background to the study as well as its sample size, content, and findings. We expect an updated profile to be published soon.

The NCDS is a birth cohort study. It follows the lives of all people born in England, Scotland and Wales in one particular week of March 1958. The birth sweep collected information about 17,415 newly born babies – an amazing 98 per cent of all the births in Great Britain that week.
At 7, 11 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 a total sample of 18,558 cohort members, who have been followed ever since. There has inevitably been some attrition from the sample, but retention rates over six decades have been very strong.
We have collected objective measures of health in both childhood and adulthood.
Medical examinations during childhood, at ages 7, 11, and 16, measured height, weight, vision, hearing, speech, and motor coordination, and recorded information on a range of medical conditions.
The Age 44 biomedical sweep measured vision, hearing, blood pressure, height, weight, waist and hip circumference and lung function. Non-fasting blood samples were collected and (with consent) immortalised cell lines were created and DNA extracted and stored for medical research purposes. A wide variety of assays of the blood were conducted.
These measures, combined with the vast amount of self-reported information about health provided by parents and cohort members throughout life provide researchers with fantastic opportunities to study factors associated with good and poor health throughout the life course.
Mental health and wellbeing have been continually assessed from childhood through to mid-life in NCDS.
Childhood mental health was assessed via medical examination, parent reports and teacher reports. Mental health has been tracked through adulthood (since age 23) using the ‘Malaise’ scale and other measures (including CIS-R at 44), alongside self-reported measures of depression and other mental health problems.
On wellbeing, a life satisfaction scale has been repeatedly measured since age 33 while richer scales of wellbeing have also been more recently included (CASP at 50 and 55, Warwick Edinburgh Mental Well-being Scale at age 50) This comprehensive suite of measures provide researchers with unparalleled opportunities for studying trajectories of mental health and the interplay between mental health and other domains of life.
During the childhood sweeps, information was collected about parental occupations, education, employment and income.
Cohort members have themselves provided detailed information about their own occupations, education, employment and income during each adult sweep making NCDS ideal for studying patterns of economic and social mobility, within and between generations.
The early sweeps of NCDS also collected information about grandparents’ occupation, and at age 62 we aim to find out about the occupations of their children – enabling analysis over four generations. The similar information collected in the other cohort studies gives researchers the opportunity to examine how mobility has changed across successive cohorts.
NCDS is a valuable resource for studying the development of cognitive ability during childhood, and cognitive function in adult life, as well as how cognitive abilities impact upon all aspects of life.
Cognition was first measured at age 7 and then throughout childhood at ages 11 and 16.
In adulthood, basic skills assessments were conducted at age 34, vocabulary assessments were conducted with a sub-sample at age 37 and the Age 50 sweep included assessments of memory, executive function and concentration. The Age 62 sweep will also measure cognition, as will future sweeps, allowing for the study of changes in cognition associated with ageing.
In the Age 50 Sweep, cohort members were asked for consent to link health and economic data to the survey data. Cohort members were able to agree to both, one or neither.
Some data have now been linked and are available to access through the UK Data Service:
Linked health data are available from Hospital Episode Statistics (HES) in England for 1997-2017 (accident and emergency, admitted patient care, critical care, and outpatient). Linked health data from Scottish Medical Records (SMR) for 2000-2015 (outpatient, inpatient and day care, maternity, Prescribing Information System) will be available soon.
Future data linkage
We are currently applying to refresh the HES linkages which will include COVID-19 data and plan to also refresh the SMR records.
We are pursuing linkages to records kept by the Department for Work and Pensions and HM Revenue & Customs, including about benefit claims, participation in employment programmes, jobs, earnings, tax and National Insurance.
