It has been observed that migrants often cross a range of countries before reaching their final destination in Europe . This phenomenon is called transit migration, migrants are increasingly risking their lives when moving in this way. Because of fear over illegal immigration and for humanitarian reasons transit migration has become a cause of concern for public and policy alike. This paper looks at the emergence of the concept and surveys some empirical studies. It examines the discursive use of the idea, its politicised character and blurred nature, and highlights some methodological difficulties in studying transit migration. Finally, some human rights and policy implications will be raised.
