Migration and the Future

This chapter explores the emerging dynamics that will define the future of global migration, focusing on four major areas: environmental change, lifestyle migration, irregular migration, and the relationship between health and mobility. It begins by analyzing how climate change—through rising sea levels, drought, and extreme weather—will increasingly drive human displacement and reshape migration patterns. Case studies such as Hurricanes Maria and Ian illustrate how environmental shocks can transform temporary evacuation into long-term migration, even within developed nations. The chapter then turns to lifestyle migration, highlighting how affluence, globalization, and remote work have enabled new forms of voluntary mobility among middle-class professionals and retirees seeking alternative ways of living. In contrast, it examines irregular migration and the intensifying securitization of borders, emphasizing how economic demand, inequality, and political instability sustain unauthorized movements despite restrictive policies. Finally, the chapter investigates the intersection of migration and health, particularly through the lens of the COVID-19 pandemic, showing how global mobility both facilitates and is disrupted by public health crises. Together, these themes underscore that the future of migration will be shaped by climate stress, technological change, health insecurity, and enduring global inequality.
