On April 2 the National Archives released online census records for 1940 and the site received more than 22 million hits in the first three hours, which temporarily crashed the website. Individual records from a decennial census are made available every 10 years, as soon as the government’s legally mandated 72-year waiting period ends. The nearly 4 million images of handwritten census pages provide information on person’s names, ages, addresses, marital status and number of children. The website is at http://1940census.archives.gov/ and you need to first identify the enumeration district before you can find the names and addresses you are seeking.
The Davis Family Library also has individual family census records for 1790 to 1930 for Vermont on microfilm and the Genealogy Research Guide can provide more detailed information for researching family history.
