Upon the abolition of slavery in the USA, there were suddenly millions of former slaves set free. But they were left without an obvious workplace. On the other side, millions of jobs done previously by slaves were now without manpower.
I would guess that at least some slaves stayed as – now paid – employees of their former owners, while those who were brutally mistreated, or who hoped they could find better employment elsewhere, just left.
However, I don't know about the statistics. There are many detailed articles about the end of slavery in the US, discussing different futures of freed slaves (some getting their own farms, some migrating North, even a very few migrating to Africa), but no statistics are given.
Were those who stayed an insignificant number, the majority, or somewhere in-between?
Are there detailed statistics? Or if there aren't, can at least rough estimates be inferred? I'm referring to former slaves being in the direct employ of their former owners, so cases of getting the land they worked on as their own, don't count.
