Migrant sex work
Sex work and sex trafficking conflation is also a heavily debated legal topic. Several scholars argue that existing legal provisions aimed at combating human trafficking, such as the U.S. Trafficking Victims Protection Act and the 2000 United Nations Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children, do not adequately account for the variety of sex worker conditions and contexts, voluntary or involuntary. For instance, Filipina hostesses who migrate to Japan to work as entertainers must give up their legal documents to their recruiters during the migration process. While the law considers the process of giving up a passport to a third party intermediary as a condition of human trafficking, several scholars, activists, and the sex workers themselves do not regard this to be human trafficking, particularly when individuals consent to this component of the migration process.
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.
