What was South slave population in 1730?

The South's slave population in 1730 was approximately 150,000. This number was a relatively small percentage of the total population of the region, which was about 1.5 million. However, the slave population was growing rapidly, and by 1770 it had reached nearly 500,000. This growth was due in large part to the high birth rate among slaves and the importation of new slaves from Africa. The slave population was also concentrated in certain areas of the South, particularly in the coastal regions and the Mississippi Valley.
