What are the 3 regions of colonial settlement in what is today the united states and what was their economy based on?

Northern, middle, and southern colonies.

Explanation:

The northern colonies had the largest population of any of the colonial regions and were the most similar in regarding to religion. However, this religious zeal began to give way before a growing economy in the early to mid eighteenth century. Rich merchants began to have more influence than puritan preachers. Fish was New England's major export, but livestock and timber also were major exports in the New England economy which was tied to the Atlantic trade routs.

Economically, the Middle Colonies focused mainly on being self sustaining. They lived on family farms where they grew enough to live on. They did not focus on growing large amounts of cash crops like the Southern Colonies. However, the Middle Colonies did export a significant amount of wheat, which made many colonists in this region very wealthy.  

The Southern Colonies also had their own unique traits. The major export in the Southern Colonies was tobacco, which was grown in very large quantities on large plantations. The tobacco business was a very labor intensive process. The southern colonies quickly became the most wealthy region of the British colonies. The wealthiest southerners dominated southern politics and created an oligarchy.
