SCOTTISH HOUSEHOLD SURVEY: Methodology 2003/2004

Appendix 1
Scottish Mosaic

Scottish MOSAIC is a neighbourhood classification system developed by Experian. It draws on a large number of Census variables, augmented by some published non-Census information, to generate a way of discriminating between postcodes in terms of housing and population types, and densities. The system has 12 broad groups, subdivided into 47 types. The whole of each postcode is allocated to whichever MOSAIC category appears the most appropriate, on the basis of the overall statistics for the postcode. This 'geo-demographic' system has been used in the sampling for the SHS.

At the sampling stage, it enables us to stratify postcodes by MOSAIC type prior to drawing the addresses for the survey, thus ensuring that our random sample of addresses properly reflects the profile of Scotland. In 2000, the MOSAIC classification was extensively revised. While this does not affect its use for sampling, it has made MOSAIC less appropriate for analysis of the survey and makes the classification used since 2001 incompatible with previous data.
