Managing International Labor Migration in the 21st Century

Abstract

Migration is defined by the United Nations as the movement from one of the world's 200+ nation states to another for 12 months or more, regardless of the purpose for being outside the country or birth or citizenship or legal status in the new country. According to this fairly inclusive definition, there were 175 million migrants in 2000, which means that 3 percent of the world's residents are outside their country of birth or citizenship as immigrants, foreign students and workers, or unauthorized residents.
