State censuses can be as important as the federal census to genealogists but, because they were taken randomly, remain a much under-utilized resource in American genealogy. State censuses often can serve as substitutes for some of the missing federal census records - most notably the 1790, 1800, 1810, and 1890 censuses. Many state censuses also asked different questions than the federal census, thus recording information that cannot be found elsewhere in the federal schedules.
While not all states took their own censuses, and some have not survived, state and local census records can be found in many locations. Most states which took censuses usually did so every 10 years, in years ending in "5" (1855, 1865, etc.) to complement the federal census. These state census records are most often found at the state archives or state library. Many are also on microfilm through a local Family History Center of the Church of Jesus Christ of Latter-day Saints and online via commercial genealogy databases.
