The graphs show that the number of enslaved people brought to the United States slowly increased starting in the late 1600s and became highest around the mid-1700s to about 1800, before dropping afterward. Overall, only about 5.1% of the enslaved people taken from Africa ended up in the United States. The graphs by state show that places like South Carolina and Louisiana received much larger numbers of enslaved people compared to northern states like Massachusetts, Rhode Island, and Pennsylvania. The graph of countries involved in exporting enslaved people from Africa shows that several countries, including Great Britain, Portugal/Brazil, France, and Spain/Uruguay, were responsible for large numbers over time. Another graph shows that earlier enslaved people arriving in the United States mostly came directly from trans-Atlantic voyages, while later more came through intra-American transfers. The mortality graph shows that many people died during these voyages, with trans-Atlantic trips usually having mortality rates around 10–20%, while intra-American voyages varied more and became higher in the early 1800s.
