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.
Organized crime
Human trafficking for the purpose of sexual exploitation is a major cause of contemporary sexual slavery and is primarily for prostituting women and children into sex industries. Sexual slavery encompasses most, if not all, forms of forced prostitution. The terms "forced prostitution" or "enforced prostitution" appear in international and humanitarian conventions but have been insufficiently understood and inconsistently applied. "Forced prostitution" generally refers to conditions of control over a person who is coerced by another to engage in sexual activity. Official numbers of individuals in sexual slavery worldwide vary. In 2001 International Organization for Migration estimated 400,000, the Federal Bureau of Investigation estimated 700,000 and UNICEF estimated 1.75 million. The most common destinations for victims of human trafficking are Thailand, Japan, Israel, Belgium, the Netherlands, Germany, Italy, Turkey and the United States, according to a report by UNODC.
