In 1810, the slate of questions asked by assistant U.S. marshals was identical to the 1800 census. This census recorded the name of the county, parish, township, town, or city in which each family resided. Each family was listed by the name of the head of household and asked the following questions:

• Number of free White males and females aged, respectively:
  • under 10 years of age
  • of 10 years but under 16 years
  • of 16 years but under 26 years
  • of 26 years but under 45 years
  • 45 years and upward
• Number of all other free persons
