The 1810 U.S. Census

The 1810 census, dated August 6, 1810, asks the same questions as 1800, but many states' pages are lost, so check what survives before you search.

Two facing handwritten pages headed Aggregate Amount of each description of Persons within the District of Massachusetts, listing Boston, Chelsea and the harbor islands of Suffolk County with counts of free white males and females by age

The third census began on Monday, August 6, 1810. The law required an actual visit to every dwelling or to the head of every family. The questions about people did not change from 1800.

A second law that year asked the same assistants to gather facts on manufacturing, but nobody told them which questions to ask. The notes they made vary widely and sometimes appear right on the population pages, such as a count of a family's looms, sheep, or yards of cloth.

  • Maine was part of Massachusetts.
  • Ages are as of August 6, 1810, even when the visit came later. In Salem, Massachusetts, the count ran from August 6 to August 29.

Other schedules
