On 01 April 2012, the 1940 Census will be released from the 72-year privacy mandate!
There will be NO index available, however, and so researchers will be required to know the Enumeration District in the city or town where their ancestors lived.
If you would like to help in this effort, visit www.stevemorse.org for more details about a project to create a free time-saving tool for your fellow genealogists.
