Classification uses
4 (a)Please state for which statistical purposes (surveys etc.) this classification is used and if there are users outside of the Statistical Office. Please indicate at which level the classification is used for data collection and for data publishing.The NS-SEC is used as a measure & good predictor of health, educational & other outcomes.
4 (b)Please give the names of institutions that use the classification for non-statistical purposes (as opposed to statistical purposes in question 4(a)). Also indicate the kind of use (e.g. tax offices, social security, customs, enterprise register, employment services, work permits etc.)Users include academic researchers, schools, colleges & universities, market researchers.
Data collection - operational category/sub-category & analytic class level.
Data publishing - usually analytic class level
4 (c)Please indicate if alternative classifications are used by other institutions of the economy. Are these classifications available and useful for the Statistical Office?The Market Research Society (MRS) uses its own Social Grade classification. A mapping of the NS-SEC to an approximated social grade was produced for the 2001 Census.
