Below, I have included videos from the National Archives. These short films were created by the US Census Bureau to train the 1940 census enumerators on their general duties and responsibilities. The first one is a general overview. The second is a training video reviewing the major questions relating to the general population. The third and fourth video relate to the housing and agriculture census. These last two censuses are no longer available, as they were destroyed. But, nonetheless, they are interesting to watch.
. How many of your parents, grandparents will finally show up for the first time in this census?
These videos give a good visual of what life was like in 1940.
