In Chapter 2, “Social Exclusion: A Lens for Understanding Aging in the Context of Migration,” Amanda Grenier and Jill Hanley explore the merits of thinking through social exclusion as a conceptual framework to better understand the experience of aging within the context of migration, in terms of the structural, organizational, and relational issues at the intersections of aging and migration and how they affect the lives of older migrants. Using composite examples at micro, meso, and micro levels of community-based practice, they illustrate dimensions of social exclusion in action, and how these affect the experiences of older migrants in the contexts of family sponsorship, dependency, and care. The authors underscore the need for a critical agenda that links the analysis of social exclusion with mechanisms for inclusion through advocacy and political change.
