This unique book examines variability among custodial grandparent caregivers. It focuses on diversity among grandparent-headed families in domestic and international settings, with over 35 contributors exploring the many factors that contribute to such diversity. It also examines diversity across individual differences especially those of gender and age, ethnicity and race, and culture. An awareness of their uniqueness is essential to the process of understanding the demands of custodial grandparents’ new roles, and in providing appropriate services to them. Whatever the reason, most grandparents raising grandchildren never anticipated that they would parent again. For most, this new role causes significant upheaval in their lives. Problems contributing to stress may include having to give up or reduce hours of work, early retirement, and providing the financial and emotional support for their grandchildren. This book is a valuable resource for practitioners and extension educators who work with grandparents’ raising their grandchildren. It provides a wealth of information and a basis on which national and state-run services can evaluate their current policies and devise funds, services, and programs that will help this growing population successfully raise their grandchildren and our nation’s future leaders.
