What is the total number of human trafficking victims worldwide?
Although it is difficult to measure the magnitude of human trafficking, the International Labour Organization estimates that more than 20 million men, women, and children are victimized by forced labor and sex trafficking worldwide, including the United States.

Several National Institute of Justice (NIJ)-sponsored studies provide interesting data on human trafficking within the United States:
  • Estimating the Size and Structure of the Underground Commercial Sex Economy in Eight Major US Cities (March 2014)
  • Labor Trafficking in North Carolina: A Statewide Survey Using Multistage Sampling (2018)
  • Thirty Percent of Migrant Laborers in San Diego Experience Trafficking Violations (July 2013)
