Sex trafficking
Sex trafficking is human trafficking for the purpose of sexual exploitation, including sexual slavery. A victim is forced, in one of a variety of ways, into a situation of dependency on their trafficker(s) and then used by said trafficker(s) to give sexual services to customers. There are three types of activities defined as sex trafficking crimes: acquisition, transportation and exploitation; this includes child sex tourism (CST), domestic minor sex trafficking (DMST) or other kinds of commercial sexual exploitation of children, and prostitution. Sex trafficking is one of the biggest criminal businesses and it has been described as "the fastest growing criminal industry in the world."
Human trafficking
According to estimates from the International Labour Organization (ILO), every year the human trafficking industry generates 32 billion USD, half of which ($15.5 billion) is made in industrialized countries, and a third of which ($9.7 billion) is made in Asia. A 2011 paper published in "Human Rights Review", "Sex Trafficking: Trends, Challenges and Limitations of International Law", notes that, since 2000, the number of sex-trafficking victims has risen while costs associated with trafficking have declined: "Coupled with the fact that trafficked sex slaves are the single most profitable type of slave, costing on average $1,895 each but generating $29,210 annually, [there are] stark predictions about the likely growth in commercial sex slavery in the future." Sex trafficking victims rarely get a share of the money that they make through coerced sex work, which further keeps them oppressed. , profits from human trafficking were about around 150 billion USD each year ranking it along with drug trafficking as one of the most profitable transnational crimes.
