4 SAR users disciplines

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

6 Thinking ahead to 2001 What will be possible? Flexible outputs? Secure settings? Larger data handling capabilities? Different disclosure constraints?... Need to fix a starting point as soon as possible Balance diverse user needs and disclosure control and production/maintenance costs No single solution - portfolio of products

7 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

8 Possible portfolio 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
