The U.S. has taken 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. While the questions in U.S. census records varied from year to year and in state censuses, from state to state, you can find information like names of other household members, ages, birthplaces, residence, occupation, immigration and citizenship details, marriage information, military service and more. The 1890 census was largely destroyed in a fire, but we have compiled a “substitute” with various other records to help bridge the gap.
