ESDS overview
• New national data archiving and dissemination service, running from 1 Jan. 2003 – 2008
• Provides access and specialist support for key economic and social data
• UK Data Archive is a service provider of ESDS and preserves and supplies most of the data
• Other partners include MIMAS and the Cathie Marsh Centre for Census and Survey Research (CCSR) and the Institute for Social and Economic Research (ISER)

Specialist data services
• ESDS Government• ESDS International• ESDS Longitudinal • ESDS Qualidata
Provide - dedicated web sites - data and documentation enhancements - user support - training

Benefits of the large-scale government datasets
• 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
![Page 6: Access to Data via the ESDS/UKDA Jack Kneeshaw ESDS/UKDA.](https://reader036.fdocuments.us/reader036/viewer/2022062312/5515ec5b550346d46f8b51df/html5/thumbnails/6.jpg)
ESDS Longitudinal
• 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

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
• Major resource for understanding the dynamics of British households
• Coverage includes:– income, labour market behaviour, social and political
values, health, education, housing and household organisation
• Recently large new samples were introduced in Scotland, Wales and Northern Ireland

British Birth Cohort Studies
• Impact of childhood conditions on later life and understanding children and families in the UK
• National Child Development Study follows a cohort born in a single week in 1958 - data collected at birth & ages 7, 11, 16, 23, 33, 42
• 1970 British Cohort Study follows a cohort born in a single week in 1970 - data collected around birth & ages 5, 10, 16, 26 and most recently at age 30
• Millennium Cohort Study focuses on children born in 2000 / 2001 - first sweep at 9 months, second sweep at 3 years
• Wide range of social, economic, health, medical and psychological measures

ESDS Qualidata
• Data from ESRC individual research grant awards
• Data from ESRC Programme research grant awards
• Data from ‘classic’ social science studies
• Other funders/sources
• Focus on DIGITAL Collections, but also facilitate paper-based archiving
![Page 11: Access to Data via the ESDS/UKDA Jack Kneeshaw ESDS/UKDA.](https://reader036.fdocuments.us/reader036/viewer/2022062312/5515ec5b550346d46f8b51df/html5/thumbnails/11.jpg)
Types of qualitative data
• Diverse data types: in-depth interviews ; semi-structured interviews; focus groups; oral histories; mixed methods data; open-ended survey questions; case notes/records of meetings; diaries/research diaries
• Multi-media: audio, video, photos and text (typically transcriptions)
• Formats: digital, paper, analogue audio-visual
• Data structures - differ across different ‘document types’
• Scope for re-use across different disciplines
