From the U.S. Census News Release:
In anticipation of the April 2 release of 1940 Census records from the National Archives, the U.S. Census Bureau is launching a new page on its website. Strict confidentiality laws ensure that census records are only unsealed after 72 years have passed, so genealogists, historians and researchers have waited with great eagerness for this release.
The site features an interactive overview of the 1940 Census, including questions asked on the census form, history facts, blogs, a 1940 Census video, pictures and a countdown clock. From the site, users will also find a direct link to the National Archives website for looking up individual 1940 Census records.
In addition, there is a newly released infographic providing a rich visual depiction of how characteristics of the U.S. population have changed between 1940 and 2010. This is the first in a series of three infographics that will explore topics related to the 1940 Census.
