HC Deb 27 March 1991 vol 188 cc409-10W
Mr. Dewar

To ask the Chancellor of the Exchequer if he will publish a table showing the derivation of the financial year gross domestic product market price deflators now used in Cm 1520, together with a similar derivation for the financial year gross domestic product market price deflator without adjustment for the effect of the introduction of the community charge.

Mr. Mellor

The GDP market price deflator for past years is calculated from the ratio of data on cash and constant price figures for GDP at market prices. Figures for the current year and future years are Treasury forecasts. Details of the method used to adjust the GDP deflator series to remove the discontinuity associated with the abolition of domestic rates, are given in paragraphs 7 to 12 of appendix A of the "Statistical Supplement to the 1990 Autumn Statement"—Cm 1520. The unadjusted GDP deflator series consistent with the adjusted figures published in Cm 1520 is:

Unadjusted GDP deflator (1989–90 = 100)
1963–64 11.2
1964–65 11.7
1965–66 12.3
1966–67 12.8
