Migration is a process in which individuals and groups of people leave their homes for various reasons. The current mobility of people is higher than ever before in modern history1 and continues to increase sharply, becoming one of the determining global issues of 21st century. Almost all of the approximately 200 world states are countries of origin, transit or destination for the migrants.
