International Migration: Definition, Causes and Effects

This paper explores the concept of migration, and its causes and effects, with a focus on international migration. Various journal articles, reports, and policy documents are reviewed to address the controversies concerning the concept and key issues of migration. The paper indicates that migration is not only a contested concept, but migration research has resulted in different outcomes. It is mainly affected by personal, socio-economic, and political factors associated with the origin and host countries. Similarly, scholars have been asking the question, “who is a migrant?” for decades without a definite answer. It is also important to consider “what would happen after migrants obtain host country citizenship”: would they continue to be migrants, the host countries’ citizens, or both? This paper contributes to advancing our knowledge and broadening our understanding of the concept of migration and key issues associated with it. It also serves as a base for further discussion.
