The United States 1920 Census, conducted one month from January 5, 1920, determined the resident population of the United States to be 106,021,537 - an increase of 15.0 percent over the 1910 Census. The 1920 census covers 95 to 97 percent of the population.<br><br>Federal census takers were asked to record information about every person who was in each household on the census day. 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 Commerce Department's Census Office in Washington, D.C.<br><br>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.
