Why has international migration become an issue of such intense public and political concern? How closely linked are migrants with terrorist organizations? What factors lie behind the dramatic increase in the number of woman migrating? This very short introduction looks at the global phenomenon of human migration - both legal and illegal - to reveal that migration actually presents opportunities that must be taken advantage of in light of the current economic climate. The author debunks myths such as the claim that migrants take jobs away from local workers, and that they take advantage of the health care system and western living conditions without returning any benefits of their own, and reveals that society as we now know it can not function without them. Not only do migrants fill a key gap in the domestic labour market, they also have a significant impact on the economies of their home countries - in places such as Mexico and the Philippines, the remittances they send home often exceed official development aid. Using interviews with migrants from around the world, the author presents the human side of topics such as asylum and refugees, human trafficking, migrant smuggling, development, and the international labour force. His goal throughout is to allow readers to see beyond the negative spin usually given the subject by the media and politicians, and come to their own conclusions on the international migration situation today.
