This is a concept used to describe the ways in which care responsibilities are transferred from one household to another, across national borders, forming chains. As individuals move, work in the care sector is internationalized. Through these chains, households in different places around the world are interconnected, as they transfer care giving tasks from one household to another based on power hierarchies such as gender, ethnicity, social class, and place of origin. Global care chains are a phenomenon which is taking place within the context of globalization, feminization of migration, and the transformation of social welfare states. Chains are formed when women migrate to work in the care sector (domestic work, personal healthcare services, etc.), while transferring care work in their own households in origin and sometimes in destination to other women.
