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."
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.
