Navigating the 1940 U.S. Census - free webinar now online by Thomas MacEntee but I'm going to watch it later today (it's free until 19 March 2012 here).
Is it perfect? No, mainly because I don't know the death date of many of the persons on this list, and they may live in a place other than the birth, marriage or death place in my database. I'll gladly take this imperfect list to doing the 1940 census search by a trial and error process.
UPDATE 10:45 a.m.: In my haste, I neglected an even better report - the "Print a Census List Report." Geoff noted this in the comment to my initial post. This report provides the married name, birth date, death date, age at death, and a possible location, with an estimate of the probability based on all of the information available in the file. Here's a screen shot of it:
I'm sure that Geoff will highlight the process, and all of the Census Tool features, in the webinar on Friday, and my guess is that I have missed many of the features that have been added to help researchers with a Census search.
