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."

On the other hand, a federally funded task force conducted a survey and instead looked at a sample of victims reported to the authorities. It found that sex trafficking represented the second largest type of human trafficking at 46%, with labor trafficking representing the largest share at 54%. The discrepancy in results between reported and documented cases could possibly be explained by the fact that sex trafficking is more familiar to authorities, and as a result has a higher chance of being investigated.
