Why Census Records are Important: Few, if any, records reveal as many details about individuals and families as do the U.S. federal censuses. The population schedules are successive "snapshots" of Americans that depict where and how they were living at particular periods in the past. Because of this, the census is often the best starting point for genealogical research after home sources have been exhausted. Some Enumerator Instructions: The 1920 Census was begun on 1 January 1920. The actual date of the enumeration appears on the heading of each page of the census schedule, but all responses were to reflect the individual's status as of 1 January, even if the status had changed between 1 January and the day of enumeration. For example, children born between 1 January and the day of enumeration were not to be listed, while individuals alive on 1 January but deceased when the enumerator arrived were to be counted. The following questions were asked by enumerators: a.. Name of street, avenue road, etc. b.. House number or farm c.. Number of dwelling in order of visitation d.. Number of family in order of visitation e.. Name of each person whose place of abode was with the family f.. Relationship of person enumerated to the head of the family g.. Whether home owned or rented; if owned, whether free or mortgaged h.. Sex i.. Color or race j.. Age at last birthday k.. Whether single, married, widowed, or divorced l.. Year of immigration to United States m.. Whether naturalized or alien n.. If naturalized, year of naturalization o.. Whether attended school any time since 1 September 1919 p.. Whether able to read q.. Whether able to write r.. Person's place of birth s.. Mother tongue t.. Father's place of birth u.. Father's mother tongue v.. Mother's place of birth w.. Mother's mother tongue x.. Whether able to speak English y.. Trade, profession, or particular kind of work done z.. Industry, business, or establishment in which at work aa.. Whether employer, salary or wage worker, or working on own account ab.. Number of farm schedule Due to boundary modifications in Europe resulting from World War I, some individuals were uncertain about how to identify their national origin. Enumerators were instructed to spell out the name of the city, state, province, or region of respondents who declared that they or their parents had been born in Germany, Austria-Hungary, Russia, or Turkey. Interpretation of the birthplace varied from one enumerator to another. Some failed to identify specific birthplaces within those named countries, and others provided an exact birthplace in countries not designated in the instructions. There are no separate Indian population schedules in the 1920 census. Inhabitants of reservations were enumerated in the general population schedules. Enumerators were instructed not to report servicemen in the family enumerations but to treat them as residents of their duty posts. The 1920 census includes schedules for overseas military and naval forces.
