In the event of war a National Register was taken that listed the personal details of every civilian in England and Wales. The 1931 census was destroyed by fire. No census was taken in 1941 because of the war. So the 1939 register is the only national census-like resource available for this period. Findmypast has searchable indexes; database results and some digitized images are available with a fee-based subscription.
