  • a web-based download service
  • specialist user support (linking with specialist support provided by the Centre for Longitudinal Studies (CLS))
  • training and workshops
  • a range of value-added data enhancements for a number of key UK longitudinal data collections, including the National Child Development Study (NCDS)

The NCDS is a continuing longitudinal study that seeks to follow the lives of all those living in Great Britain who were born in one particular week in 1958. The aim of the study is to improve understanding of the factors affecting human development over the whole lifespan.

The NCDS has its origins in the Perinatal Mortality Survey (the original PMS study is held in the Data Catalogue under SN 2137). This study was sponsored by the National Birthday Trust Fund and designed to examine the social and obstetric factors associated with stillbirth and death in early infancy among the 17,000 children born in England, Scotland and Wales in that one week. Selected data from the PMS form NCDS sweep 0, held alongside NCDS sweeps 1-3, under SN 5565.


To date there have been seven attempts to trace all members of the birth cohort in order to monitor their physical, educational and social development. The first three sweeps were carried out by the National Children's Bureau in 1965, 1969 and 1974. These sweeps form NCDS1-3, held together with NCDS0 under SN 5565. In 1985 the NCDS moved to the Social Statistics Research Unit (SSRU) - now known as the Centre for Longitudinal Studies (CLS) - and the fifth sweep was carried out in 1991. The sixth sweep was conducted in 1999-2000 and the seventh in 2004.

Sweep ID Year Age Study Number
1 NCDS1 1965 7 5565
2 NCDS2 1969 11 5565
3 NCDS3 1974 16 5565
4 NCDS4 1981 23 5566
5 NCDS5 1991 33 5567
6 NCDS6 1999-2000 41-42 5578
7 NCDS7 2004 46 5579

The NCDS has gathered data from respondents on child development from birth to early adolescence, child care, medical care, health, physical statistics, school readiness, home environment, educational progress, parental involvement, cognitive and social growth, family relationships, economic activity, income, training and housing.


Access to the NCDS

Users registered with the Economic and Social Data Service (ESDS) have access to the NCDS datasets via the instant download service or can analyse, visualise, subset and download selected data from NCDS via the online Nesstar software tool.

Users can register with ESDS at: www.esds.ac.uk/aandp/access/login.asp

NCDS - ESDS data holdings and planned future developments

The NCDS data currently available via ESDS cover sweeps 0-7. In addition, a small number of studies based on sub-samples of cohort members of interest to particular research questions are available; for example, data collected in the course of a special study of handicapped school-leavers, at age 18 (held under SN 2024) and data from a 5 per cent feasibility study, conducted at age 20 (held under SN 2025), which preceded NCDS4. A parent migration dataset, based on NCDS5, is held under SN 4324, and a study detailing partnership histories, compiled from NCDS sweeps 5 and 6, is held under SN 5217.

Very usefully, a separate dataset covering response to NCDS over all seven sweeps is available under SN 5560, National Child Development Study Response Dataset, 1958-2005.
