The main causes of human trafficking are poverty, war, and other social issues. Some women are made to believe promises of a better life, sometimes by people who are known and trusted to them. Traffickers may own legitimate travel agencies, modeling agencies and employment offices in order to gain women's trust. Others are simply kidnapped. Once overseas it is common for their passport to be taken away by the trafficker and to be warned of the consequences should they attempt to escape. This may include beatings, rape, threats of violence against their family and death threats. It is common, particularly in Eastern Europe, that should they manage to return to their families they will only be trafficked once again. When an area has a lot of prostitutes some people say its a "sexidemic" (too much).
