In all of its work, Trajectoires makes an effort to take into account the phenomena of influence on vulnerable publics, notably those who by nature of their migration are more exposed, and which can often create obstacles to their ability to be included in common law protection systems.

As such, the identification of instances of Human Trafficking (defined in France by the article 225-4-1 in the penal code) is part of an integrated methodology the organization uses when conducting social diagnosis and action research.
Trajectoires focuses on less-studied phenomena of exploitation: pressure to commit crimes, coerced begging, exploitation within encampments, etc.
