Final answer:
The large increase in the African American population in the Southern Colonies between 1700 and 1770 can be attributed to high natural population growth among African Americans and the continued demand for enslaved labor.
Step-by-step explanation:
The large increase in the African American population in the Southern Colonies between 1700 and 1770 can be attributed to several factors. The large increase in the African American population in the Southern Colonies between 1700 and 1770 can be attributed to high natural population growth among African Americans and the continued demand for enslaved labor.
One of the main reasons was the high natural population growth among African Americans. Slaves were forced to reproduce, which contributed to the increase in population. Additionally, the demand for enslaved labor remained high during this period, as cash crops like tobacco and sugar required a large labor force.
