  1. Accessing the NCDS and the BCS70 via the Economic and Social Data ServiceJack KneeshawNCDS/BCS70 workshop 19 March 2009 ESDS Longitudinal

  2. Economic and Social Data Service • provides access and support for key economic and social data • distributed service, bringing together centres of expertise in data creation, dissemination, preservation and use • core archiving services plus four specialist dataservices

  3. ESDS Longitudinal Jointenterprise: • UK Data Archive (UKDA) • UK Longitudinal Studies Centre (ULSC) based at ISER • supports a range of longitudinal data collections but seven ‘core’ collections in particular: • National Child Development Study (NCDS) • 1970 British Cohort Study (BCS70) • Millennium Cohort Study (MCS) • British Household Panel Survey (BHPS) • English Longitudinal Study of Ageing (ELSA) • Longitudinal Study of Young People in England (LSYPE) • Families and Children Study (FACS)

  4. Data Deposit, Processing, Retrieval and Access

  5. The data themselves - NCDS

  6. The data themselves – BCS70

  7. Data not held by the ESDS • some additional data, derived from further minor data collections, data cleaning etc., only available via CLS at present • these data are added to the ESDS collection from time to time

  8. Ensuringconfidentiality • cohort members promised confidentiality • datasets deposited with ESDS are fully anonymised • datasets go through further process of checking at the UKDA • ESDS users undertake not to identify individuals

  9. Documentation A variety of NCDS/BCS70 documentation is available, including: • guides to datasets • lists of publications • annotated questionnaires • interactive data dictionaries • ‘Data Notes’ series • other survey-related documentation, inc. working papers etc. Available both from CLS and ESDS web sites.

  10. Retrieval and access • web access, via ESDS site, to data and metadata • documentation (codebooks, questionnaires) freely available to any ESDS user (registered or unregistered) • data can be browsed and frequencies run by any user (registered or unregistered) using Nesstar • full datasets are freely available for download for the majority of our registered users • data supplied in a variety of formats • SPSS • Stata • tab-delimited text

  11. Special licence access • several ‘special licence’ (SL) datasets have recently been made available: NCDS: biomedical, local authority 1958-74 BCS70: county data 1986, 1996, 2000 • strategy to provide access to datasets that are detailed, yet anonymised • as these data pose a higher risk of disclosure, they have additional special conditions attached to them • the SL requires the signature(s) of the researcher(s) and the institution with responsibility for the researcher; also needs the explicit permission of the data owner to release the data to the researcher(s)

  12. Online access for registered users Registered users can: • download full datasets • order data via online order system • browse/analyse/download data in Nesstar To register: • login via UK Fed or Athens • click-through or sign/return data access agreement (legal undertaking) • (to access data) register a usage (formerly a project)
