Centre for Longitudinal Studies (CLS)

The Centre for Longitudinal Studies (CLS) is an ESRC Resource Centre, based at the Institute of Education, University of London. CLS houses three of Britain's internationally-renowned birth cohort studies:

  • 1958 National Child Development Study (NCDS) - "a continuing, multi-disciplinary longitudinal study which takes as its subjects all those living in Great Britain who were born between 3 and 9 March, 1958."
  • 1970 British Cohort Study (BCS70) - "a continuing, multi-disciplinary longitudinal study which takes as its subjects all those living in Great Britain who were born between 5 and 11 April, 1970,"
  • Millennium Cohort Study(MCS) - a continuing, longitudinal study whose sample was "drawn from all live births in the United Kingdom over 12 months (from 1 September 2000 in England and Wales and for 59 weeks from 22 November 2000 in Scotland and Northern Ireland)."

CLS provides support and facilities for those using data from the three studies, as well as conducting research using the cohort data, with a special interest in family life and parenting, family economics, youth life course transitions and basic skills. CLS does not provide access to the actual data.
