Preparations for taking the 1941 Census were interrupted by the outbreak of war on 3 September 1939 and the census never went ahead. The National Registration Act 1939, which set up a national register for the issue of identity cards, authorised the Registrars General to compile the register using the administrative machinery already being prepared for the census. But the new registration recorded far less information than the census – simply name, address, sex, marital status, age and occupation. Some statistics from the 1939 register were published in 1944, but they were not comparable with those from previous censuses.
