1790 Census Population Results

As Secretary of State in 1790, Thomas Jefferson was chief administrator of the first census. He certified the results reported by marshals and assistants in the original 13 States plus the districts of Kentucky, Maine, Vermont, and the Southwest Territory (Tennessee). A total of 3.9 million people were counted in the first census, although for apportionment purposes the count was around 3.6 million.
