1940 Census Records

As we indicated in Census Records a census must be 72 years old before it is available to the public. In 2012 the 1940 US Federal Census became 72 years old and so on April 2, 2012 The U.S. National Archives and Records Administration (NARA) provided public access to the 1940 Census for the first time. The NARA provides free digital images of the Census.

The 1940 US Federal Census records contain important information about ancestors - like the names and ages of parents, children and siblings. In addition you can find information about an individual's education, birthplace, employment status, occupation and wage and salary information for 1939.

For a complete list of the information contained in the 1940 Census as well as the information that is included in all previous US Census years see Information in Census Records - 1870 through 1940. Here you will find the information recorded for each census year from 1870 through 1940.

Search the 1940 Census

The National Archives (NARA) provides access to the images of the 1940 Census and these records can be read free of charge at 1940 Census Records.

When the census data in the 1940 Census was released in 2012 it was not indexed. So for example you couldn't enter an ancestor's name and find the page where his or her census records are located. However, it is now indexed and searchable at the major genealogy sites that offer access to the 1940 Census.

So for example you can go to Family Search - 1940 US Census where you can enter an ancestor's name and find his or her census records.

You can also organize your searches around the enumeration districts used in 1940. These districts refer to the area of a city or town that an enumerator (census taker) covered when asking the census questions. If you know where a person was living in 1940 then you can find the enumeration district and this will help you find that person in the Census.

Find a 1940 Enumeration District

NARA has provided a number of ways to find the 1940 Enumeration Districts at Online Public Access. Here you can search the 1940 Census Maps to find the name and number of the Enumeration District in which your ancestor lived.

Here is how to search for the Enumeration District - enter 1940 Census maps + the county + the state. Here is an example used by NARA - 1940 Census maps Sussex Delaware. When you receive your search results you will find a map and you should zoom into the map to find the street location where your ancestor lived. You will see the Enumeration District printed on the map - the first number is the county number and the second number is the enumeration district number within the county.

If you don't know where a person was living in 1940 you might look at the 1930 Census to find where the person was living in 1930. You might also try a Telephone or City Directory that was compiled around 1940 and World War II Draft records might also indicate where a particular family was living in 1940. You can also try looking at family records that might contain an address - letters and envelopes, newspaper clippings and passports as well as birth, marriage and death certificates.

Once you know the Enumeration District then you can find information about your ancestor in the online 1940 Census.

Search Census Records

In general the US Census is indexed by the words or terms found on the written census. So if there were spelling mistakes on the written census these misspellings will appear on the indexed census. If you can't find a census record for your ancestor try different spellings in your search terms.

You might also try different search terms that are spelled correctly. For example change the search for "Raymond Kane" to a search for "Ray Kane". If Ray Kane was transcribed from the written census then you will probably find your ancestor's written census record with this search term.
