Between 1525 and 1866, 12.5 million Africans were shipped to the New World.
10.7 million survived the dreaded Middle Passage, disembarking in North America, the Caribbean and South America.
Only about 388,000 were shipped directly to North America.
Some scholars estimate that another 60,000 to 70,000 Africans ended up in the United States after touching down in the Caribbean first, so that would bring the total to approximately 450,000 Africans who arrived in the United States over the course of the slave trade.
