§ Ms CorstonTo ask the Chancellor of the Exchequer what was the average equivalised disposable income per adult at 1990 prices for 1979, 1987 and 1990 of(a) single-parent households, (i) with one child and (ii) with two or more children, (b) two-parent households with (1) one child, (2) two children and (3) three or more children and (c) other households with children by quintile and decile groups of households.
§ Mr. NelsonThe information is not available in the precise form requested because the equivalence scale used is based on households rather than adults. In addition, the figures are only available at current prices.

The one adult with children household type is not subdivided further for the same reason.
Any difference between the average equivalised disposable income of household types within a quintile group is likely to result from sampling errors.
These figures are not strictly comparable over time because of changes in classification of both income and taxation and because of changes in the "Family Expenditure Survey".
