Question

How did the north population differ from the south's population?

Answer 1

Hello!

The North's population primarily consisted of white people. The north also had many abolitionists (people against slavery).
The South, however, was made up of white people and slaves. Most white people in the South agreed with the idea of slavery and promoted it. 

I hope this helps answer your question!

Answer 2

The North's population was much larger than the South's.
