– The state of Ohio was included for the first time in the 1810 Census. However, the original information from Ohio and some others states have been lost or destroyed. These include Georgia, Mississippi, New Jersey, Tennessee, and the District of Columbia.
Inconsistency of Format – There were no standard forms for the census in 1810. Therefore, the format varies as widely as the number of enumerators.
Native Americans – Most Native Americans in the US were not counted on the 1810 Census. At this time, “Indians not taxed,” which were those living on reservations or in unsettled territory, were not counted.
