Global migration is a multi-disciplinary field of academic inquiry dedicated to understanding the complex processes, causes, patterns, and consequences of human movement across international borders. It investigates the diverse forms of transnational mobility, the structural factors driving it, the experiences of migrants, and its profound socio-economic, political, and cultural impacts on individuals, societies, and global systems. This concept serves as a critical lens for analyzing the dynamics of population redistribution, inequality, development, and international relations in an increasingly interconnected world.
