Why did more enslaved Africans live in South Carolina than did white people?

More enslaved Africans lived in South Carolina than white people did, because the southern colonies were most plantation colonies, so they were made up of slaves working on agriculture with a few wealthy families and plantation owners. These colonies were rural and made all their wealth from crops, so they essentially were based on needing more manual labor than they did people running the plantations or families living in the area.
