Collection Time Period
The U.S. federal census was conducted each decade from 1790 to the present. This information pertains to the census conducted in 1920.

Collection History
Federal census takers were asked to record information about all those who were in each household on the census day, which was 1 June for the 1920 census. A census taker might have visited a house on a later date, but the information he collected was supposed to be about the people who were in the house on the census day. The basic census enumeration unit was the county. Each county was divided into enumeration districts, one for each enumerator. The completed forms were sent to the Census Office in the Commerce Department in Washington D.C. The 1920 census covers 95-97% of the population.

Why This Collection Was Created
The U.S. federal census was taken at the beginning of every decade, beginning in 1790, to apportion the number of representatives that a state could send to the House of Representatives in Congress. In the absence of a national system of vital registration, many vital statistics and personal questions were asked to provide a statistical profile of the nation and its states.

Collection Reliability
Federal censuses are usually reliable, depending on the knowledge of the informant and the care of the census enumerator. Information may have been given to a census taker by any member of the family or by a neighbor. Some information may have been incorrect or deliberately falsified.
