The regulation of prostitution in the country is not among the enumerated powers of the federal government. It is therefore exclusively the domain of the states to permit, prohibit, or otherwise regulate commercial sex under the Tenth Amendment to the United States Constitution, except insofar as Congress may regulate it as part of interstate commerce with laws such as the Mann Act. In most states, prostitution is considered a misdemeanor in the category of public order crime–crime that disrupts the order of a community. Prostitution was at one time considered a vagrancy crime.
