§ Mr. John Mooreasked the Secretary of State for Social Services what was the total number of returns made in each census for which figures are available; and what 100 per cent. would have produced in numbers of total returns for the same period.
§ Mr. MoyleA single return may apply to a person, a household, or an institution; the number of returns is not available but the number of persons in England and Wales returned in recent censuses has been:
1951 43,757,888 1961 46,104,548 1971 48,749,575 The census in this country covers an overwhelming proportion of the population. In 1951 and 1961 the estimated percentage covered was 99.69 and 99.98 respectively. In 1971 a detailed study was undertaken and it was estimated that there had been a net over-enumeration of 0.01 per cent.; this was attributed 551W to persons being returned as present on census night at more than one address.
§ Mr. John Mooreasked the Secretary of State for Social Services how many compulsory questions were asked in each of the censuses for which such details are available.
§ Mr. MoyleUsing, so far as practicable, a comparable definition of what constitutes a single question, the numbers of questions—or parts—asked at each census in England from 1841 onwards have been as follows:
1841 8 1851 8 1861 8 1871 8 1881 8 1891 12 1901 11 1911 17 1921 13 1931 11 1951 20 1961 33 1971 32 In Wales, there has been an additional question on Welsh language from 1891 onwards.
§ Mr. John Mooreasked the Secretary of State for Social Services what was the cost of the census for each census for which figures are available.
§ Mr. MoyleThe cost charged to the Census Vote of the General Register Office for England and Wales is as follows:
£000 1851 94 1861 96 1871 120 1881 123 1891 121 1901 148 1911 162 1921 351 1931 300 1951 1,550 1961 3,100 1971 13,500 From 1951 the figures include also sums chargeable to the Votes of Departments other than the General Register Office.
§ Mr. John Mooreasked the Secretary of State for Social Services why there was no discussion in the White Paper on the 1981 census, Command Paper No. 7146, 552W on how much of a census needs to be compulsory as opposed to voluntary.
§ Mr. MoyleThe Census Act 1920 provides no basis for voluntary questions.
