Source: 1939 England and Wales Register

Initially taken due to the onset of war with the purpose of producing National Identity Cards, the register later came to be multi-functional, first as an aid in the use of ration books and later helping officials record the movement of the civilian population over the following decades and from 1948, as the basis for the National Health Service Register. The 1939 Register is an extremely important genealogical resource, not only for the rich detail and information recorded for each person and household, but also in helping to bridge a thirty-year gap in census data. The census taken in 1931 was destroyed during the Second World War and no census was carried out in 1941 due to the ongoing conflict. The register, as held by The National Archives, contains data only for England and Wales and does not include records from households in Scotland, Northern Ireland, the Channel Islands or the Isle of Man.
