Saint-Domingue absorbed roughly ten percent of the entire Atlantic slave trade.

Evidence

Over 100,000 slaves were reported to have died during the middle passage, and many more deaths probably went unrecorded. Starting in the late 1730s, between 10,000 and 20,000 African men, women, and children were imported to Saint-Domingue each year. By the middle of the 1780s that number had risen to 30,000 to 40,000. Imports reached their peak in 1790, when nearly 48,000 Africans were disembarked in the colony. This number does not include the slaves imported into the colony before the eighteenth century, nor does it account for the constant influx of slaves brought in via the thriving contraband trade, which naturally left few written traces. We will never know exactly how many slaves were brought to Saint-Domingue. Estimates range from 850,000 to a million. Even though it became a full-fledged plantation society later than other Caribbean colonies and was destroyed decades before the end of the Atlantic slave trade, Saint-Domingue accounted for perhaps 10 percent of the volume of the entire Atlantic slave trade of between 8 and 11 million. — Dubois, Laurent, Avengers of the New World_ The Story of…, 147
