For most enslaved African Americans in the 1800s,

In the early 19th century, most enslaved people in the US South performed primarily agricultural work. By 1850, only 400,000 enslaved people lived in urban areas—where many engaged in skilled labor such as carpentry, blacksmithing, and pottery. Almost three million worked on farms and plantations. Because most of the agricultural output of the South was produced on large plantations, more than half of all enslaved men and women lived on plantations that had more than 20 enslaved laborers; about a quarter lived on plantations that had more than 50.

I hope I can help you :) Have a great day
