Sex trafficking
There are a number of misconceptions about sex trafficking. Sex trafficking and human trafficking are not to be confused with human smuggling. Human trafficking for sexual or other labor may involve transporting victims across international borders, but to meet the definition of trafficking, there needs only to be exploitation of an individual after they have been coerced or deceived, so it does not necessarily involve transportation across national borders. Human trafficking and sex trafficking are often used as synonyms. However, trafficking for non-sexual exploitation may be even more prevalent than trafficking for sexual exploitation, though accurate estimates of trafficking rates are extremely difficult to obtain. Sex trafficking tends to receive more attention from aid organizations and donors due to the greater public outrage that forced sexual labor evokes compared to forced non-sexual labor and thus incidents of sex trafficking are more frequently reported.
Sex worker
While demographic characteristics of sex workers vary by region and are hard to measure, some studies have attempted to estimate the composition of the sex work communities in various places. For example, one study of sex work in Tijuana, Mexico found that the majority of sex workers there are young, female and heterosexual. Many of these studies attempt to use smaller samples of sex workers and pimps in order to extrapolate about larger populations of sex workers. One report on the underground sex trade in the United States used known data on the illegal drug and weapon trades and interviews with sex workers and pimps in order to draw conclusions about the number of sex workers in eight American cities. However, studies like this one can come under scrutiny for a perceived emphasis on the activities and perspectives of pimps rather than those of sex workers themselves. Another criticism is that sex trafficking may not be adequately assessed in its relation to sex work in these studies.
