§ Mr. SquireTo ask the Secretary of State for Social Security if he will publish a table showing the number of(a) working heads and (b) dependants facing marginal tax and benefit withdrawal rates in excess of 50 per cent. in the manner of his answer on 25 March 1988, Official Report, column 244.
§ Mr. Peter LloydPrecise details can be provided only in overall terms. On the basis of the earlier reply the figures for families with children are as follows. Before taking account of the effect of the March 1988 Budget, an estimated 510,000 workings heads with 1.4 million adult and child dependants had marginal deduction rates of over 50 per cent. Post-Budget, 480,000 working heads with 1.3 million dependants were in this category. The underlying assumptions are those used in "Impact of the reformed structure of income related benefits" October 1987, copies of which are in the Library. Similar figures for working heads without children are not available.
