Once primarily thought of as a medical issue, disability is now recognized as a critical issue of identity, personhood, and social justice. By discussing challenges confronting people with disabilities, their families, and accounts of disability experiences, this volume situates disability within broader social movements, policy, and areas of marginalization, providing a critical examination of the experiences of people with disabilities and how disability can affect identity. A foundational introduction for those intimately connected with a person with a disability and those interested in the science behind disability, this collection covers all aspects of disability in the US. Topics cover characteristics of disability; disability concepts, models, and theories; important historical developments and milestones for people with disabilities; prominent individuals, organizations, and agencies; notable policies and services; and intersections of disability policy with other policy.
