1 Requirements for 2011 Cross-sectional Microdata Ed Fieldhouse SARs Support Team University of Manchester

2 The SARs family 2001 FileSample typeGeographyAvailability Individual Licensed SAR 3% sample of individuals UK: GOR (+ Wales, Scot, NI, Inner/Outer London) EUL CCSR Small Area Microdata 5% sample of individuals UK: LA (or constituency in NI) EUL CCSR Special Licence Household SAR 1% hierarchical file None: England and Wales only Special Licence UKDA Individual CAMS Same sample as Individual Licensed SAR LA (GB) or Constituency (NI) IMD info for SOA In house at ONS Household CAMS 1% hierarchical file All of UKIn house at ONS

3 Our first thoughts for Data in secure setting (CAMS) –100% population data (with sub-setting)? –Flexible tabulation and/or multivariate analysis –Download facility/bespoke samples? –Confidentiality checks –Widen number of locations Special Licence files –SL Household SAR (with large households) –SL Individual SAR (with LAD geography) –Special topic samples (e.g. employment) General purpose files –Safe data (EUL) with less detail –Available publicly and to overseas researchers

4 Key features Coverage Size Ethnicity and religion Geography Multivariate Household structure Comparability with other census products Easy access

5 Importance of features 2011

6 Key considerations Safe setting or safe data (or other access arrangements) Varied user requirements Expert users versus general users Geographical detail versus variable detail versus sample size Set-up and maintenance costs

7 Independent consultancy: The value of the SARs Marginal cost of output as compared to the cost of the census Diverse range of uses Real life value – not well reflected in usage figures: e.g. –Informs sampling –Synthetic data for policy planning –Monitoring equal ops Untapped demand

8 From the independent report: Ideas for 2011 Broad agreement on key points Need to reflect the diversity of uses with appropriate products: –Simple data for quick reference –Professional use data –Access to full detail in secure setting Clear timescales are necessary to allow users to plan
