International Migration as a World Issue

Abstract

In the twenty-first century, migration has become a global phenomenon, not only because of the sheer number of people involved in migratory flows throughout the world (284 million international migrants, or 3% of the world population), but above all because of its ubiquity: no region, no country in the world is unaffected by migratory flows, and all countries in the world are involved either in emigration, or in immigration, or as a transit country. Most countries are involved in all three of these processes to some extent.
