The United Kingdom Census of 1841 recorded the occupants of every United Kingdom household on the night of Sunday 6 June 1841. The enactment of the Population Act 1840 meant a new procedure was adopted for taking the 1841 census. It was described as the "first modern census" as it was the first to record information about every member of the household, and administered as a single event, under central control, rather than being devolved to a local level. It formed the model for all subsequent UK censuses, although each went on to refine and expand the questions asked of householders.
