U.S. Census
The United States has conducted a census of its population every ten years since 1790. The most recent census available to us at present is the 1940 census, due to a 72-year privacy restriction.
MyHeritage has the full set of USA census records from 1790 to 1940, with a total of 650 million names. These records constitute the single most important source of documentation for family history in the USA.
