§ Mr. Nicholas BrownTo ask the Chancellor of the Exchequer what was the total and average investment income and earned income in 1989–90 and 1990–91 of(a) the top 1 per cent., (b) the top 5 per cent., (c) the top 10 per cent., (d) the bottom 70 per cent., (e) the bottom 50 per cent., (f) the bottom 10 per cent., of taxpayers and (g) all taxpayers.
§ Mr. Maude[holding answer 25 February 1991]: Estimates are in the table.
167WAll estimates are provisional and subject to a wide margin of error since they are based on a projection of the 1988–89 survey of personal incomes and the coverage of investment income in the survey is incomplete. In some cases investment income on which basic rate liability is satisfied by deduction at source is not reflected in the survey. Information on the investment income of the bottom 10 per cent. of taxpayers is not available.
