ILO estimates 27.6 million people are in forced labor worldwide. Global estimates put total modern slavery at 49.6 million, up 12% since 2016. These figures break down into different systems of exploitation across regions, including trafficking, forced labor, and coerced work.
Key Takeaways
- British Empire abolished slave trade in 1807, freeing 160,000 by 1860 via West Africa Squadron capturing 1,600 ships
- Mauritania has 2.1% prevalence, 90,000 in hereditary slavery despite bans
- Globally, 50 million people live in modern slavery as of 2021, including 28 million in forced labor and 22 million in forced marriages
- By 1820, Brazil had imported 4 million slaves, comprising 35% of its population
- 18th-century Virginia imported 45,000 slaves, shifting to internal trade post-1808 ban
- The Trans-Atlantic Slave Trade forcibly displaced approximately 12.5 million Africans between 1525 and 1866, with detailed records showing 10.7 million survived the Middle Passage to arrive in the Americas
Slavery still affects millions today, making urgent action on forced labor and exploitation more necessary than ever.
