This series contains estimates of Approximated Social Grade for all Household Reference Persons aged 16 to 64 years and for all usual residents in households using the grade of the Household Reference Person, aged 16 to 64 years.

There are two univariate datasets, SG001EW for Household Reference Persons and SG002EW for usual residents in households. There are an additional 11 multivariate datasets (SG003EW to SG013EW), most of which are for characteristics of usual residents in households with Household Reference Persons aged 16 to 64 years.

This socio-economic classification is used by the market research and marketing industries to analyse spending habits and consumer attitudes. It is not possible to assign social grade precisely from Census 2021, although the Market Research Society's method provides a good approximation.
