Book excerpt: Aging and Social Policy in the United States guides students through an exploration of social policies and policymaking that address the needs of older adults and their families. It situates the experiences of older adults in the context of their environment, examining social welfare policies that affect the rights and interests of older adults. The book begins with an introductory unit, providing a foundation for the book, defining key terms, describing how to analyze the impacts of a policy on a population, and examining the ways in which policy is positioned within societal assumptions. Utilizing the life course perspective, the middle three units of this book situate individual biological and psychological challenges of aging in the context of how they are addressed by individuals, families, and societies, identifying the strengths and challenges of existing and proposed social policies at each of these levels. The concluding unit provides comparative insights as to how aging issues are addressed in a sample of countries around the world. Aging and Social Policy in the United States provides undergraduate and graduate students with critical knowledge and perspectives on the complexities of addressing the needs of an aging population.
