HC Deb 24 January 1980 vol 977 c364W
32. Sir Brandon Rhys Williams

asked the Chancellor of the Exchequer what is his estimate of the number of single people claiming single person's tax allowance, who are not householders.

Mr. Lawson

About 5 million, not all of whom pay tax after taking account of the allowance. This estimate is for 1977, the latest year available, and is based on the family expenditure survey.
