Human trafficking is complex and dynamic. It is widespread but exact numbers are hard to come by. It follows patterns, but every situation is also unique. There is so much more to learn.

1. Trafficking involves transporting someone into a situation of exploitation. This can include forced labor, marriage, prostitution, and organ removal. This kind of exploitation is known by a few different names — “human trafficking,” “trafficking of persons,” and “modern slavery” are the ones accepted by the US Department of State.

2. It is estimated that internationally there are between 20 million and 40 million people in modern slavery today. Assessing the full scope of human trafficking is difficult because so cases so often go undetected, something the United Nations refers to as “the hidden figure of crime.

3. Estimates suggest that, internationally, only about .04% survivors of human trafficking cases are identified, meaning that the vast majority of cases of human trafficking go undetected.

4. Human trafficking earns global profits of roughly $150 billion a year for traffickers, $99 billion of which comes from commercial sexual exploitation.

5. Globally, an estimated 71% of enslaved people are women and girls, while men and boys account for 29%.
