World Migration Report

In the 21st century, an estimated 150 million people live outside their countries of birth or citizenship. This means are more migrants than ever before. This text explains how growing ethnic diversity affects economies, cultures, and political institutions, and challenges existing forms of citizenship and national identity. The report presents the basis for understanding the complex issues involved and offers analysis of related aspects. It also looks at the increasingly global economy which has led to an unprecedented influx of newcomers in many countries and examines trafficking, smuggling and the related human and legal aspects.
