Chattel slavery is characterized by ownership of one person by another and individuals in this form of slavery are bought and sold as commodities. It is the least common form of human trafficking today; however, it was the most prevalent in the United States until the 1865 passage of the Thirteenth Amendment to the United States Constitution.
Early and forced marriage primarily affects girls and women who are married to men without any choice. They then live as servants to the men and often experience physical and/or sexual violence in the home environment.
Forced labor is characterized by an individual being forced to work against her or his will, without compensation, with restrictions on freedom, and under violence or its threat. This term is also sometimes used in reference to all forms of human trafficking.
Involuntary domestic servitude is a form of forced labor in which an individual performs work within a residence such as cooking, cleaning, childcare, and other household tasks. This becomes trafficking when the employer uses force, fraud and/or coercion to maintain control over the individual and to cause the worker to believe that she or he has no other options but to continue in the position. This type of environment puts the individual at increased risk because she or he is isolated and authorities are not able to easily gain access to inspect the workplace.
