census questions

The census records contains the recorded answers to questions. NARA has put the census forms and questions online. The 1940 census form is available as a scanned image of an original blank census form, as a printable PDF, and even as fillable online form.
Many questions asked in the 1940 census are identical to questions asked in earlier and later census. There were supplementary questions, including the place of birth of father and mother, a question that is be very helpful to genealogists. Other supplemental questions of interest to genealogists are the mother tongue, whether the person is a veteran, whether the person has a social security number, and whether a woman has been married before.
The page that contains all this ends with a helpful list of abbreviations used.

enumerator instructions

The census forms were filled in by the enumerators. To fully understand how they did, you can read the enumerator instructions. NARA has put both Abridged Instructions to the Enumerator and Complete Instructions to the Enumerator complete with Occupation and Industry Classifications.

enumeration districts

The 1940 census is organised by enumeration district (ED). You do not need to wait for the 1940 U.S. Census Community Project to complete the name index, but can immediately search the census by enumeration district. In fact, even when the name index has been completed, you may still want to search by enumeration district.
The main challenge is finding the enumeration for a 1940 address. NARA has the 1940 Census Maps that show the enumerations districts, but although this available through their Online Public Access search, using the maps to finds the enumeration districts is doing it the hard way.
The easy way is using the census utilities that Stephen Morse has added to his famous One Step pages. The ED Finder find the enumeration district for all cities with more than 50.000 inhabitants, the ED Description utility for 1940 find the enumeration district for rural areas, and last but not least the 1930/1940 ED Converter utility converts from a 1930 enumeration district to a 1940 enumeration district.
