While transnational migration research primarily focuses on working migrants and the logics of the labor market, it is becoming increasingly clear that older people also participate in seasonal cross-border relocations. Professional disengagement, increased life expectancy, material security, consumption-oriented lifestyles, biographical travel experiences, and harmonizations within the EU facilitate living in two or more places in Europe. After providing a theoretical foundation for transnational aging migration, Claudia Kaiser analyzes the migration system using Mallorca as a case study, examining the actors, their life worlds, and transnational practices, while highlighting the contradictions of the aging process under the conditions of transnational aging migration. The book is aimed at educators and students in sociology and geography.
