1940 US Census

The 1940 US Census was the sixteenth census taken by the United States Census Bureau and was taken during the second year of World War 2 but was finished more than a year and half prior to the entry of the United States into the war. The census determined that the population of the U.S. was 132,164,569 which represented a population growth of 7.3% as compared to the 1930 census. When the records of the census were released by the National Archives on April 2nd, 202 after the mandatory 72 year waiting period, it provided the first consolidated database of archive files for the Americans who participated in WW2 available for use in military records and family research from the time.

The official record date of the 1940 Census was April 1st, 1940; however, information was collected for the full month of April that year. There were a number of questions added to the survey that include the highest education level reached, wage information, where personnel were located five years before, and also introduced new sampling techniques. For the first time, one person in every 20 that was surveyed was asked additional questions on their census questionnaire. There was also a field test conducted of the planned census questions in 1939. The census fulfilled the federal requirement that a United States census be taken every ten years in order to determine the appropriate number of representatives each state is entitled to in the United States House of Representatives. The first U.S. Census undertaken was in 1790.

1940 Census Information
In the United States, the census is the only record that provides a comprehensive description and the issues relevant to most of the population of the country on that given day. The 1940 U.S. Census accomplished this task similar to the other census’ that have been taken in the country since 1790. Since the data from the census was made public in 2012, the information provided includes specifics on how the Great Depression and FDR’s New Deal program in the 1930s impacted Americans. During this timeframe, the population of the various American territories was assessed to be 2,477,023 persons (Puerto Rico, Alaska, American Samoa, Hawaii, Guam, American Virgin Islands, and the Panama Canal).
A change when compared to past censuses, the U.S. 1940 one had surveys taken only by enumerators who went door to door in the United States to collect information. If someone was out when the enumerator visited, they would come back. People were also counted who were living in trailer camps, hotels, and tourists during the survey and were counted on April 8th and 9th, 1940.

How to Search 1940 Census Data by Name
Unfortunately, the U.S. Government project that makes 1940 Census data available for free online does not yet have a by name search capability included on the website. If you are unable to locate the information that you require for either a military records or family genealogy search, then turning to a commercial product is likely the answer. One of the websites that I have used to research family members who took part in WW2 is archives.com. If you are in for a “one-off” lookup, the site has a seven day free trial period. On the seventh day, you get charged for the service, so make sure to try it out and cancel if you don’t want to make use of the number of features offered by the service.
Step 1 – Register for the archives.com service to help find Your Ancestors.
