United States Census State Censuses

Additional information may be found on the United States Census Portal page.

Historical Background
State censuses were often taken in the years between the federal censuses, such as 1875 or 1892. For some states these exist from about 1825 to 1925. They are found in state archives, and copies of most are on microfilm at the Family History Library. The library's most complete collections of state censuses are for Illinois, Iowa, Kansas, Massachusetts, Minnesota, Mississippi, New Jersey, New York, Rhode Island, and Wisconsin.

They are usually listed in the Locality Search of the Family History Library Catalog under [STATE] - CENSUS RECORDS.
