Twenty-First-Century Migration as a Challenge to Sociology

International migration is, by definition, a social phenomenon that crosses national borders and affects two or more nation-states. Its analysis requires theories and methodologies capable of transcending the national gaze. This applies more than ever in the current epoch of global migratory flows and growing South–North mobility. Sociology claims to be based on the work of scholars from around the world and to have theories and methods valid for all societies. It should therefore have an important role in the development of global migration studies. Yet national approaches, deriving from historical projects of nation-building, have often been dominant. Moreover, the study of migration has been peripheral in national scientific discourses and hierarchies. This has often led to the diverging dual roles of the sociology of migration either as an administrative tool based on micro-analyses of ‘social problems’, or as a form of social critique cut off from actual struggles in institutions, workplaces and neighbourhoods. This article argues for a global sociology of migration, devoted to analysis of migration as part of the social transformations associated with globalisation, and based on global networks of scholars.
