Global interactions: migration systems processes and policies.

The authors use examples from the other 17 chapters in this book to help describe the key elements of a systems approach to the study of international migration. They conclude that "in an increasingly interconnected world few countries can be simply categorized as receivers or senders of migrants and only the adoption of a wide perspective with regard to migration can advance our understanding about the coexistence of inflows and outflows of migrants from the same country or of the simultaneous admission of highly skilled workers and low-skilled ones by another." The geographical scope is worldwide. (EXCERPT)
