asked the Chancellor of the Exchequer by what amount disposable income has risen since April 1974 in money terms, and in real terms, and in percentage terms on each basis.

Monthly estimates of disposable income are not available. The latest quarterly estimates, seasonally adjusted, show that between the first quarter of 1974 and the third quarter of 1979 personal disposable income increased in money terms by £20 billion—145 per cent.—and in real terms by £2 billion—10½ per cent—when measured at constant 1975 prices.
