The United States Constitution requires that a population census be undertaken every ten years to determine the appropriation of seats in the United States House of Representatives and for the collection of taxes. The United States was the first nation to legislate a regularly held census. This seventh census taken in the United States recorded the population as of June 1, 1850. It was the first census in which was collected information about every member of a household, instead of the name of the household and the number of inhabitants. It was also the first census to include a question of a person's place of birth.
Enumerators of the 1850 Federal Census were required to use for the first time in the Census's history printed schedules.
