As the third census of the United States, the 1810 census was to be completed within nine months (later extended to 10 months), using August 6, 1810 as the official enumeration date. Questions regarding residency and age were based on that date.
Using the name of the head of each household, Census enumerators were asked to count the number of free white males & females by age category, all other free persons (except Indians not taxed), and slaves. New in 1810, the first inquiry on manufacturers' equipment and product values were certified by census enumerator and Assistant Marshall William W Bryan on January 11, 1811.
Stamped and handwritten page numbers were later added to the census. Somehow, pages 224-248 were reversed before the page numbers were assigned. Also, no page was designated as "223". To view the original page order, view the chart at the bottom of this page.
