1921 United Kingdom census

The United Kingdom Census 1921 was a census of the United Kingdom of Great Britain and Ireland that was carried out on 19 June 1921. It was postponed for two months from April due to industrial unrest and no census was taken in Ireland due to the Irish War of Independence. It was the first census in the UK to ask about place of work and industry, and whether a marriage had been dissolved by divorce.[1]
