Through a social justice and equity lens, this book examines how families, sport, and leisure connect to broader social issues in society. It goes beyond describing oppression and disadvantaged identities and focuses on advocacy and ways forward to challenge the status quo. Adopting an interdisciplinary approach, the book draws upon different theories to present important new work on topics as diverse as the role of parents and siblings within youth sport; the family in sport for development and peace; and grandparent–grandchild relationships in sport, leisure, and family tourism. Several topics also bring attention to the multiplicity of family lives such as LGBTQ older adults as well as children and young people in the care of the state. Together, these studies provide important insight into how sport and leisure reflect and refract key contemporary social issues within the context of familial lives. This is fascinating reading for any student or researcher with an interest in sport, leisure, education, development, sociology, social work, or social policy.
