Washington DC Population History

The District of Columbia was formed in 1791 from territory ceded by Maryland and Virginia, but remained in some respects under their jurisdiction until the National government moved there in 1800. The District included the existing small cities of Georgetown and Alexandria as well as the site chosen for the Nation's new capital, Washington. In 1846 the portion south of the Potomac River, including Alexandria, was retroceded to Virginia.

In 1800 the census reported the District as part of Maryland and Virginia. All populations shown in the table exclude the portion returned to Virginia in 1846.
