Final answer:
Most enslaved people according to the 1790 census lived in the Southern states, with heavy concentrations in farming regions and certain cities in the Lowland South.
Step-by-step explanation:
According to the 1790 census, most enslaved people lived in Southern states of the United States. In particular, they were largely concentrated in the Lowland South, on farms, and in cities such as Charleston, New Orleans, and Atlanta. The Chesapeake region also had a significant number of slaves, who were involved in tobacco cultivation. The enslaved population underwent a massive change between 1790 and 1810 due to the expansion of Southern states and territories. The number of slaves did not increase rapidly until the mid-1830s with the boom in cotton production, despite the doubling of the free population in the South over that period. By 1860, the population of enslaved African Americans grew dramatically to 3.95 million, marking one of the largest forced internal migrations in the United States.
