The 1940 census is the only U.S. Federal population census for which the researcher can be absolutely certain who answered the enumerator's questions in every household. This can be useful in evaluating the quality and accuracy of the information. Did the person giving the information know what they were talking about? Are the ages, birthplaces, and other data comparable to information found in other records?
Question 7 on the 1940 census population schedule – "Name" – asked for the "Name of each person whose usual place of residence on April 1, 1940, was in this household." It also directed that "Ab" be written after the names of any person temporarily absent from the household and to record any child under the age of one as "infant" if it had not been given a name. Finally, it directed the enumerator to "Enter (X in a circle) after name of person furnishing information." This image shows the "Name" instruction block which is at the top of each census page:
The 1940 Federal Population Census can be found online in the National Archives Catalog at "Population Schedules for the 1940 Census" at and on websites such as Ancestry.com and FamilySearch.org. Happy hunting!
