Because of privacy laws that protect identifying information for 72 years, the 1940 Census is the most recent census in which records can be researched in detail.

The sixteenth United States Census officially began on April 1, 1940 and took just over a month to complete.  The total population recorded was 132,164,569.  The official cutoff for enumeration was 12:01 a.m. on April 1.  Therefore, births that occurred after this date were not included.

Unique Features of the 1940 Census

Sampling – The 1940 Census contained some questions that were not asked of every person counted.  These extra questions were only asked of about one of every twenty people to provide a data sample.

Government Workers – The 1940 census categorized government workers as either “private or non-emergency government” employees or those who performed “public emergency work.”  Public emergency work included employees of the Works Progress Administration, Civilian Conservation Corps, and the National Youth Administration.

Urbanization – The 1940 census recorded the urbanization of America with great detail.  One question asked where the person lived 5 years prior and whether or not it was on a farm.  Workers were categorized by occupation, industry, and class.  Perhaps one of the most revealing indications of urbanization was the recording of persons who lived in “hotels, tourist or trailer camps, missions, and cheap one-night lodging houses (flophouses).”

Women – Women were given more attention in the 1940 census.  The enumerators asked women if they had been married more than one time, their age at their first marriage, and how many times they had given birth.
