Benefits of the large-scale government data
Good quality data- produced by experienced research organisations- usually nationally representative with large
samples- good response rates- very well documented
Continuous data- allows comparison over time- data is largely cross-sectional
Hierarchical data- intra-household differences- household effects on individuals
Longitudinal data
Longitudinal surveys involve repeated surveys of the same individuals at different points in time
Allow researchers to analyse change at the individual level
More complex to manage and analyse
Longitudinal studies
National Child Development Study (NCDS)
British Cohort Study 1970 (BCS 70)
Millennium Cohort Study (MCS)
English Longitudinal Study of Ageing (ELSA)
Families and Children Study (FACS)
Longitudinal Study of Young People in England (LSYPE)

International macro and micro data
ESDS International is split into two types of data:
Aggregate or macrodata …are data that has been aggregated to a country or regional level. This type of data is typically produced by inter-governmental organisations like the UN or World Bank. All the aggregate databanks contain time series data.
Survey or microdata …are data about individuals. This type of data is typically produced by an organisation in the academic sector and looks at values and attitudes.
International macro dataRegularly updated macro-economic time series datasets from selected major international statistical databanks that collectively chart over 50 years of global economic, industrial and political change:
International Monetary Fund
OECD
United Nations
World Bank
Eurostat
International Labour Organisation
UK Office for National Statistics
International data themes
Databanks cover:
economic performance and development trade, industry and markets employment demography, migration and health governance human development social expenditure education science and technology land use and the environment
