Migrant sex work
Whether or not human trafficking and migrant sex work should be considered the same concept has been a contentious debate among feminist activists, government officials, scholars, and religious organizations for the past 15 years. This debate currently dominates much of the public discussion surrounding human trafficking and sex work. On one side of the debate are anti-prostitution activists who conflate migrant sex work and human trafficking because they do not believe in voluntary prostitution or because they view any migration for the purpose of sex work as human trafficking. This perspective has largely dominated mainstream governmental and NGO perspectives toward human trafficking across international contexts. On the other side of the debate are pro-sex work academics and activists who argue for the separation of voluntary migrant sex work from involuntary human trafficking and a greater focus on labor and migration rights instead of trafficking. This group works for the recognition of the right of prostitutes to pursue sex work as a legitimate form of work, more flexible and open borders for migrants, and a greater focus on the spectrum of coercive labor conditions.
Prostitution
Sex trafficking is defined as using coercion or force to transport an unwilling person into prostitution or other sexual exploitation. The United Nations stated in 2009 that sex trafficking is the most commonly identified form of human trafficking and estimates that about 79% of human trafficking reported is for prostitution (although the study notes that this may be the result of statistical bias and that sex trafficking tends to receive the most attention and be the most visible). Sex trafficking has been described by Kul Gautum, Deputy Executive Director of UNICEF, as "the largest slave trade in history." It is also the fastest growing criminal industry, predicted to outgrow drug trafficking. While there may be a higher number of people involved in slavery today than at any time in history, the proportion of the population is probably the smallest in history.
