Many of the UK's major longitudinal studies are - broadly and with caveats attached - equivalent to surveys in
other countries. Even where they are not broadly equivalent, particular survey questions/modules may be
comparable with questions/modules asked in other national and international surveys.
Ideally, this equivalence is by design (ex-ante harmonisation). Where it is not by design, it can be the
product of efforts made after the data were collected (ex-post harmonisation).
This page lists a number of key, cross-national, longitudinal data harmonisation projects (mostly ex-post) and
points users in the direction of data and resources created by these projects.
Birth cohort study harmonisation data/resources
Socio-economic/multi-purpose panel harmonisation data/resources
- Cornell University User Package for the Cross-National Equivalent File (CNEF), 1980-2008 | The
CNEF contains equivalently defined variables for the Panel Study of Income Dynamics (PSID), the German
Socio-Economic Panel (SOEP), the British Household Panel Study (BHPS), the Household Income and Labour Dynamics
in Australia (HILDA), the Korea Labor and Income Panel Study (KLIPS), the Swiss Household Panel (SHP), and the
Canadian Survey of Labour and Income Dynamics (SLID).
- European Community
Household Panel (ECHP) | The ECHP ran from 1994-2001, collecting data annually on income, living conditions,
housing, health and work in the EU. The BHPS provided the UK component of the panel.
- European Union
Survey of Income and Living Conditions (EU-SILC) | The successor to the ECHP, the EU-SILC contains
cross-sectional and longitudinal design elements. The UK's General
Household Survey has made significant adaptations to provide the UK component of the panel.
Longitudinal study of ageing harmonisation data/resources
- Survey of Health, Ageing and Retirement in Europe
(SHARE) | SHARE is a cross-national longitudinal study of ageing, covering respondents aged 50+ in 18 European
countries. Whilst the English Longitudinal Study of Ageing (ELSA) is not formally part of SHARE, both projects have
maintained comparability through harmonisation. Note: Registered ESDS users may request access to the
ELSA portion of the data from a project to harmonise ELSA Wave 2 and SHARE Wave 1 (both 2004) data undertaken by
Valeria Bordon at the University of Mannheim. Contact firstname.lastname@example.org for further details. The
SHARE portion of this joint database can be accessed via
