Information gathered: enumerate
In 1840, the Census was taken of the existing states (Delaware, Pennsylvania, New Jersey, Georgia, Connecticut, Massachusetts, Maryland, South Carolina, New Hampshire, Virginia, New York, North Carolina, and Rhode Island), the three districts (Kentucky, Maine, and Vermont) and the Southwest Territory (Tennessee.)
The census schedules (the actual written records of information from each household) were, by legal mandate, posted in "two of the most public places within [each jurisdiction] there to remain for the inspection of all concerned..." There were no forms for this Census. Each Census taker created his own schedule format.
A complete set of the schedules, along with summary data for the counties, and, in some areas, for the towns, was filed with the State Department. In 1812, when the British burned the Capitol during the war, the schedules from many of the states were destroyed. Copies had also been filed with District Courts, but many of those had been lost over the years. The records are not complete.
Remaining records are in the United States National Archives. To view microfilm of released census schedules (all schedules more than 72 years old) contact the regional NARA center at Laguna Niguel. Digitized versions can be accessed through Ancestry.com.
