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. The questions in
U.S. census records varied from year to year and in state
censuses. They typically include names of household members,
ages, places of birth, residence, occupation, immigration and
citizenship details, marriage information, military service and
more.
