The 1940 Census came at a momentous time in our Nation's history — as we recovered from the Great Depression and not long before our entry into World War II. It was also the first Census that looked deeper into the details of much of American life. Now, 72 years later, upon release of the 1940 Census forms by the National Archives, we look back and see just how much America changed.
