Currently international migration is occurring on a large scale. According to some data, in the year 2000 the number of migrants all over the world amounted to 174.8 million people or 2,9% of total world population. The lion’s share of this migration was undertaken by laborers seeking better jobs and working conditions. The globalization of the world economies has brought about the formation of a worldwide labor market, resulting in the exporting and importing of foreign labor. In the year 2001 the number of migrant laborers was approximately 40 million. If you include their family members, this total grows to 120 million people. The sheer volume of the numbers involved in the migration of international labor "significantly affects the economy and labor force of more than 100 countries."
