Access to data is handled differently for each of the studies. This page summarises the access procedure for each.

Hertfordshire Cohort Study (HCS)

The Hertfordshire Cohort Study has governance and access arrangements that comply with MRC data sharing policy. The survey data are accessible to bona fide researchers by contacting Professor Cyrus Cooper, Director of the MRC Lifecourse Epidemiology Unit at the University of Southampton, who can forward a collaborators’ agreement.

Research metadata (i.e. descriptions of the study and the questions asked) can be accessed via the MRC Gateway Portal.

 

MRC National Survey of Health and Development (NSHD)

The 1946 MRC National Survey for Health and Development (NSHD) has governance and access arrangements that comply with MRC data sharing policy. The survey data are accessible to bona fide researchers by applying through the NSHD website.

Research metadata can be accessed via the MRC Gateway Portal and the NSHD Metadata repository.

1958 National Child Development Study (NCDS)

The majority of NCDS survey data can be accessed by bona fide researchers through the UK Data Service at the University of Essex. Anyone wishing to access the data will need to register with the UK Data Service before downloading. Some datasets are only available via Special Licence, or via the UK Data Service Secure Lab. Access arrangements comply with ESRC Research Data Policy.

Data from the biomedical sweep collected in 2002/3, including most data generated from the biological samples is available via Special License. However, access to the majority of genotypes generated from NCDS participants is governed by the Wellcome Case Control Consortium CDAC. Access to genotypes linked to other variables or applications for access to DNA and for new uses of biological samples is via the Access Committee for CLS Cohorts (ACCC).

Research metadata, including basic frequencies, is available using NESSTAR at the UK Data Service. The Centre for Longitudinal Studies (CLS) website provides copies of the questionnaires and documentation used in the study. The CLS data dictionary offers further metadata including variables and frequencies.
