When Black Immigrants Outnumbered White Immigrants

In the March 2005 issue of American Heritage Yale historian David Brion Davis writes about slavery as"The Central Fact of American History."

In the course of his article he notes:

"By 1820 nearly 8.7 million slaves had departed for the New World from Africa." How many whites had emigrated by that time from Europe? 2.6 million.
