§ Ms. CorstonTo ask the Secretary of State for Social Security what was the average disposable income of households, and of adults and children, within households, at 1989 prices, for each year from 1979 to 1989, inclusive, for the poorest and for the richest 20 per cent. of households, before and after equivalisation, based on the data collected for the households-below-average-income analysis.
§ Mr. BurtThe information can be provided only at disproportionate cost. The information that is available is in the table. HBAI presents figures in a, standard format: only for years 1979, 1981, 1987 and 1988–89—that is, 1988 combined with 1989—before and after housing costs; 947W equivalised for household size and composition; using the median as the average measure for subdivisions of the income distribution; and at April 1992 prices. This is in line with the recommendations made in the stocktaking report produced last year after consultation with independient external analysts.
It is not our practice to produce unequivalised information.
