How many people around the world do you think are victims of slavery today? Modern slavery is a hidden crime that is especially hard to measure. That’s why a group of researchers came together to develop the Global Slavery Index, which measures slavery as accurately as possible. The 2016 Global Slavery Index estimates there are 45.8m people worldwide in slavery today. That is more than the entire population of Canada, Poland, Uganda or Malaysia.
