This chapter views the increase that has occurred in migration between nations as a component of the increased economic and cultural connections that have also occurred among nations (i.e. globalization). The chapter also introduces the major types of migrants, and the prevalence of each type, including: high and low-skill workers, refugees fleeing from dangerous situations, victims of traffickers, exiles, foreign students and separated family members seeking to reunify. The chapter concludes with a discussion of how migration and tourism are both similar to each other and different.
