Sexual slavery is just one reason for human trafficking, as is forced labor.
=== Forced labour === Forced labour, or unfree labour, is sometimes used to describe an individual who is forced to work against their own will, under threat of violence or other punishment, but the generic term "unfree labour" is also used to describe chattel slavery, as well as any other situation in which a person is obliged to work against their own will, and a person's ability to work productively is under the complete control of another person
 In the modern world, more than 50 percent of slaves provide forced labour, usually in the factories and sweatshops of the private sector of a country's economy
