New England geography, with its hilly terrain lent itself to small, isolated, independent farms which could be worked by small families. Vast southern plantations demanded large numbers of farmhands to work the large cash crops, and others to process or refine the crops into finished goods.
Southern colonies were a rural type of colony. The southern colonies were very rich with agriculture. These colonies were also a place to live for the wealthy. Since the southern colonies had many wealthy people, there were also a lot of slaves.
