§ Ms CorstonTo ask the Secretary of State for Social Security what was the average equivalent household income at April 1994 prices for(a) the poorest 20 per cent. and (b) the richest 20 per cent. from the latest households below average income analysis, before and after housing costs, in 1979, 1981, 1987, 1988–89, 1990–91, 1991–92, according to economic status categories (i) single or couple self-employed, (ii) single, in full-time work, (iii) couple, both in full-time work, (iv) couple, one in full-time, one in part-time work, (v) couple, one in full-time work, one unemployed or not employed, (vi) couple, one or both in part-time work, (vii) single retired pensioner, (viii) couple, both retired pensioners, (ix) single, unemployed or non-employed, (x) couple, both unemployed or non-employed, (xi) three or more adults, all unemployed or not employed and (xii) others.
§ Mr. BurtThe information is provided in the tables. It should be noted that the results do not track the income of individuals over time but compare the average median income for each group in each year shown. Changes in the average for each group over the whole period —1979 to 1991–92—are more reliable than those over shorter periods.
Care should be taken in the use of these single estimates as some are based on a small number of cases. Estimates which are particularly uncertain are shown in brackets. These are based on a sample of less than 100 benefit units.
