With the abolishment of slavery in Romania, gypsies scattered across Europe. It is estimated that 200,000-280,000 migrated to the west since 1960. Recent discrimination and violent harassment of Gypsies in Romania, Bulgaria, and the former Yugoslavia has caused many Gypsies to migrate to Western Europe. Only recently has the E.U. and international community paid to this significant minority. The greying of populations and the reduced birthrates of many couples in the industrialized world means that most industrialized nations will need migrant labor.
Many industrial countries are now concerned about the greying of their populations.
This is a global phenomenon but the effects are being felt first in the industrialized countries that had their demographic transition earlier. To achieve a numerically stable population, countries will have to have immigrants.
