HC Deb 14 April 1983 vol 40 c436W
Mr. Field

asked the Chancellor of the Exchequer if he will list the numbers of families with children living under the tax threshold for each of the past 20 years.

Mr. Ridley

[pursuant to his reply, 28 March 1983, c. 66]: I regret that information is not available on which to base estimates for each of the past 20 years A rough estimate, however, is possible for the year of the 1971 census, when about one and a half million families with dependent children did not pay income tax.
