Many studies, done by researchers, have concluded that poverty is a major factor which some families have low income, so they must find a way to increase revenue by sending their children to work in different areas. Some parents sell their children, not just for the money, but also in the hope that their children will escape a situation of chronic poverty and move to a place where they will have a better life and more opportunities. (The OSCE Action Plan, n.d., p. 454). Next, human trafficking is another factor that comes from a lack of knowledge. Especially those migrant housing and working in place is not familiar and have not the knowledge about the residential environments. One of the circumstances human traffickers benefit from is the lack of knowledge, especially among young women, about actual possibilities of migration into Western European countries: they either have no or very little information about living conditions and employment opportunities in The European Union (Aradau, 2013, p.2). Finally, the law is the important cause of vulnerability in human trafficking because there are not enough law enforcement. Which can facilitate human trafficking easier. Lack of adequate legislation and of political will and commitment to enforce existing legislation or mandates are other factors that facilitate trafficking in persons. (The OSCE Action Plan, n.d. ,
p. 455).
