What is the social differences between the North and South during the Civil War?

The North was a highly industrialized society fed by a large number of small family farms. It had a relatively large and mobile middle class, and consisted of a large diversity of ethnic groups, even though most of the nationalities were Caucasian and Protestant, but with a sizable minority of Irish Catholics. The South was primarily agrarian, largely due to a small number of large single-product cash-crop plantations owned by a wealthy minority of Caucasian Protestants, with a concentration of Catholics in and around Louisiana, but whose labor force consisted of a mix of first, second, and third generation African slaves. There was practically no manufacturing base in the South.
