Deciphering Miscellaneous Codes Appended to the 1940 Census in One Step

The codes that appear in the various lettered columns of the 1940 U.S. Census
have been summarized in a
book by Robert Jenkins
These codes were put on the census pages well after the
enumeration was done, and therefore provide no additional information. However, sometimes
knowing the code can help you determine the information in cases where the quality of the
microfilm is poor or the handwriting of the enumerator is difficult to read.
To decipher the information, enter the codes from the appropriate census column into the boxes below.
