Notes on the table data
- In the first census (1790) the mean population center was near Chestertown, Maryland.[3]
- The mean population centers of 1820, 1830, 1840 and 1850 were in what is now West Virginia, given West Virginia's split from Virginia in 1863.[3]
- Computation method used until 1950.
- Current computation method.
- The addition of Alaska and Hawaii to the union moved the center about two miles (3 km) farther south and about ten miles (16 km) farther west in 1960.[2]
