13. New York, New York
New York is one of the most popular cities in the US, a center of culture and urban life, and unfortunately, a place with a high number of human trafficking victims. As their journalist investigated, the most of the girls became prostitutes by falling in love with romantic and very charming handsome boys, which eventually become their pimps. Since the number of human trafficking victims is on the rise (almost 50% in the last few years), New York will be on the list of top US cities for human trafficking for a long time.
