The region we denominate North America, consisting of Central America, Mexico and the United States, is one where sex trafficking has been deeply rooted. This article, based on a qualitative methodology which included in-depth interviews with 155 women from Central America, offers a comparative analysis of the characteristics of the sex trafficking suffered by migrant women in the different countries of the region. It concludes that in the case of those who travel to the United States, the victims are mainly young women who are lured by sex trafficking networks with false promises of glamorous or well-paid jobs; in Mexico many victims are kidnapped by criminal groups, and in Central America, the victims are mostly minors prostituted by people who are close to them or who are deceived by pimps.
