Partners
ESDS Overview
• provides access and support for key economic and social data
• distributed service, bringing together centres of expertise in data creation, dissemination, preservation and use
• provides seamless and easier access to a range of disparate resources for UK Higher and Further Education sectors and beyond
ESDS overview
• core archiving service (UKDA) plus four specialist data services
• ESDS Government (CCSR/UKDA)• ESDS International (MIMAS/UKDA)• ESDS Longitudinal (ISER/UKDA)• ESDS Qualidata (UKDA)
• provide: value-added data and documentation service-specific web pages and help support and training teaching datasets/online samplers discussion lists/newsletters publicity and promotion
UKDA’s role
• overall integration and management of ESDS
• acquiring, processing, preserving and disseminating data
• central registration service operating across the ESDS
• central 'first stop' help desk service • cataloguing and describing data• maintaining and developing web sites• publicity and training• user support
Sources / type of data
Data for research and teaching purposes and used in all sectors and for many different disciplines
• official agencies - mainly central government
• international statistical time series
• individual academics - research grants
• market research agencies
• public records/historical sources
• qualitative and quantitative

Access to data
• End User Licence
– data can only be used by registered users (some exceptions relating to teaching)
– to preserve the confidentiality of, and not attempt to identify, individuals, households or organisations in the data
– to use the correct methods of citation and acknowledgement in publications
– to supply the bibliographic details of any published work based on the data collections
– to offer for deposit any new data collections which have been derived from the materials supplied
ESDS Government data
• General Household Survey/Continuous Household Survey (NI)• Labour Force Survey/NI LFS• Health Survey for England/Wales/Scotland • Family Expenditure Survey/NI FES• British/Scottish Crime Survey• Family Resources Survey • National Food Survey/Expenditure and Food Survey • ONS Omnibus Survey • Survey of English Housing • British Social Attitudes/Scottish Social Attitudes/Young People’s
Social Attitudes/NI Life & Times• National Travel Survey• Time Use Survey• Vital Statistics for England and Wales
Benefits of the large-scale government datasets
• good quality data– produced by experienced research organisations– UK/GB - usually nationally representative with large
samples. Interviewers all over country– good response rates– well documented, NISRA, ONS, UKDA, QB etc.
• continuous data– e.g. Continuous Household Survey 1983, allows
comparison over time– data is largely cross-sectional
• hierarchical data– individual and household– 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 analyse
ESDS Longitudinal Data
• main studies that are primarily UK Research Council:
– British Household Panel Survey (BHPS)– British Birth Cohort studies:
• National Child Development Survey (NCDS)• British Cohort Study 1970 (BCS70)• Millennium Cohort Study (MCS)
– English Longitudinal Study of Ageing (ELSA)– Longitudinal Study of Young People in England
(LSYPE) – possible forthcoming Medical Research Council
population study datasets – 1946 Birth Cohort
British Household Panel Survey
• collected and deposited by the ULSC at Essex
• follows the members of 5500 households first sampled in 1991
• interviews conducted annually
• become a major resource for understanding the dynamics of British households

values, health, education, housing and household organisation

• teaching and learning
Using ESDS data for teaching
• tutor registers with ESDS and downloads data
• registers a usage (for micro data)
• tutor makes data available to students (if online only via secure network)
• tutor asks students to register or sign access agreement for teaching (not always necessary, but to be encouraged)
