New England colonies (CT, RI, MA, NH, and VT) had small farms but excelled in shipbuilding, fishing, trading and producing rum. Middle colonies (NY, NJ, PA, and DE) produced wheat on larger farms and large port cities like New York and Philadelphia. Southern colonies (MD, VA, NC, SC, and GA) grew tobacco on large plantations and corn and rice on smaller farms. These colonies had the most slaves by far. The only city with a large population was Charleston, South Carolina. Significance-The environment-climate and soil-was a major factor in the different development of the colonies. People developed different attitudes about religion, government, and slavery, with enormous implications for the future decades.
