§ Mr. Norman Lamont[holding answer 10 March 1988] : Estimates are given in the tables for 1978–79 and 1983–84 to 1987–88. Information for other years could be provided only at disproportionate cost. All estimates are based on information reported to tax offices and collected through the annual surveys of personal incomes. For years before 1985–86, estimates exclude employees' contributions to occupational pension schemes and some investment income on which tax is deducted at source.
