The census was taken in the thirteen original states (Connecticut, Delaware, Georgia, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, and Virginia), the state of Vermont, and the districts and territories that became Kentucky, Tennessee, and Maine. Census data from Delaware, Georgia, Kentucky, New Jersey, Tennessee, and Virginia no longer survives.
