You are right. In numbers, only 400,000 African slaves were brought to what became the United States. The vast majority of African slaves were actually brought to the Caribbean and to South America, with Brazil getting more than any other country.

Two things stand out here. First of all, I had never done a study of this, so I was shocked when I first heard it. You have provided more details here.

What concerns me, is this. We got 400,000 and that’s only about 5%. This means close to ten million were taken out of Africa.

That seems like a very large number for those days.

Also keep in mind that all that early slavery happened almost 200 years before any slaves came to the U.S. in the late 1600’s early 1700’s.
If you look at the percentage of Blacks in Western European countries you find that the number there overall is less than 5%. A great deal of that due to natural migration rather than slavery.
So in the scheme of things without the practice of slavery the U.S. would probably have a natural migration of say less than 2% overall.
