HC Deb 21 December 1984 vol 70 c419W
Mr. Butterfill

asked the Secretary of State for Social Services what factors are responsible for the fall in the number of persons receiving the £1.25 blindness addition to supplementary benefit, from 41,000 in December 1982 to 36,000 in December 1983, as revealed by the Department of Health and Social Security's annual statistical inquiry.

Mr. Newton

The number of claimants receiving the blindness addition in December 1983 quoted by my hon. Friend is a provisional estimate and has yet to be confirmed. The largest variation between the figures for the two years is amongst pensioners. The figures relating to pensioners' claims are based on a sample of one case in 200 and because the total number of cases involved is quite small the figures for both years are subject to fairly large sampling errors: the apparent fall may therefore simply be caused by chance in the selection of the sample.
