The answer to that assertion is that you are wrong.
The per capita income of free populations in 1860 as complled by the United States Census was the following:
........................South..............North
...........................$150................$142
Sources: Fogel & Engerman (1860 Census), Wm. Parker
You are a LIAR. I never mentioned “free” population until I analyzed the data you provided trying to prove per capita income higher in the South.
When I realized the fraud you were attempting I pointed out how you were attempting it.
You do realize “per capita” is based upon the ENTIRE population?
