United States Census, 1920 - FamilySearch Historical Records

United States

What is in This Collection?
Index to the population schedules from National Archive microfilm publication T625, Fourteenth Census of the United States, 1920. The collection is part of Record Group 29 Records of the Bureau of the Census. The census will identify the place of residence on January 1, 1920 for each person counted. The collection is arranged alphabetically by state, then by county, and by enumeration district (ED). Enumeration districts may not always be arranged in numerical order within each state. The index was created by FamilySearch and Ancestry.com.

Population schedules were recorded on large sheets with rows and columns. The schedules are arranged by state, county, place, and enumeration district. The districts are not always filed in sequential order. The arrangement of families on a schedule is usually the order in which the enumerator visited the households.

Federal census takers were asked to record information about all the people who were in a household on the census day, which was 1 January for the 1920 census. A census taker might have visited the residence on a later date, but the information collected was to have been about the people in the residence 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 of the Commerce Department in Washington, D.C. The schedules cover 95 to 97 percent of the population.

The U.S. federal census has been taken at the beginning of every decade, beginning in 1790, to apportion the number of representatives a state could send to the House of Representatives. 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.

Federal censuses are usually reliable, depending on the knowledge of the informant and the care taken by the census enumerator. Realize that any family member or even a neighbor may have supplied information to the census taker. Some information may have been incorrect or deliberately falsified.
