Today, there are 40.3 million slaves on the planet. Today. And the locations of slaves are visible via satellite imagery. Via ⁦@bigthink 

For those only aware of or focused on slavery in the past: In 1981 [sic], Mauritania became last country to abolish slavery. But the number of slaves has been estimated to be 43,000 (or 1.0% of the population) and possibly up to 600,000 (or 17%!) in 2015. 

If you want to know more about how the institution of slavery actually works, in 2019 [sic]!, in countries throughout the world (in Africa and Asia especially), see this remarkable book by @achoifitz 

Your periodic reminder that there is slavery in the world today, not just in the past: Nigerian 'torture house': Kaduna school was 'like hellfire'
