This survey focuses first on defining prostitution and then on the motivations of prostitutes. In Part II the overall scope of the problem is examined, along with the various subcultures (e.g., street walkers and call girls) and the prevalence of drugs, crime and victimization. Part III covers teenage prostitution and the issues of child sexual abuse. Part IV details other dimensions of the sex trade industry, such as pornography, male prostitutes, customers, laws, and the effects of decriminalization and legalization. Female prostitution outside the United States is discussed in Part V.
