According to the census of 1790, about how many free people of african ancestry lived in the colonies?

760,000

Explanation:

This is the amount of free people of African ancestry that lived in the colonies according to the census of 1790. This shows that free African people were common throughout the history of the United States. However, their status became more compromised as slavery became more entrenched. During the 1800s, plantations became more productive, which increased the demand of African slaves and put free people of African ancestry in a more precarious situation.
