As the global population ages, disability demographics are shifting. Societal transformation and global health inequities have changed who is likely to reach old age, who is likely to live with disability, and the relationship between aging and disability in various socio-cultural and geopolitical contexts. The Aging–Disability Nexusbreaks new ground by bringing gerontology and disability studies into dialogue. This thoughtful examination of competing narratives about disability and aging explores the distinction between aging witha disability and aging intodisability, revealing how multiple identities, socio-economic forces, culture, and community give form to our experiences.
