This book is about the phenomenon of transit migration to Europe, and its impact on states and people.This book presets topical subject: the issue is politicized and mediatized. It combines new research data with an originality in approach: both top-down and bottom-up. It focuses inside and outside Europe.Challenging traditional approaches to migration, which see migrants in narrow categories (legal and illegal, newcomer and settler), "Transit Migration" shows that migrants and refugees live in transit for years, a stage in the migration course profoundly affecting destination countries and the migrants themselves.
