Article I, Section 2 of the United States Constitution states of the census:
"The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct."
Therefore, every 10 years, since 1790, the U.S. government has conducted a census of the population of its states and territories. The directing administrator or agency has changed from the Secretary of State (1800 to 1840), to the Interior Department (1850 to 1900), to the Department of Commerce's Bureau of Census (1902 to present). If you are looking for pre-1980 data on a specific state, please see our State Censuses subject guide.
The following census materials contain no names. Instead, they feature statistical demographic data that is helpful in painting a picture of a particular geographic location. See Bureau of the Census Catalog of Publications: 1790-1972 (C 3.163/2-2:790-972) for a comprehensive guide to statistics published by the Census Bureau from 1790 to 1972.
