US census records — the researcher's most-used source, decoded

Short answer

US census records are the backbone of American genealogy. Taken every ten years since 1790, they snapshot the country's population at a moment in time and — from 1850 onward — name every person in every household. The most recent public release is the 1950 census, opened by NARA in April 2022.
