In his preface to this volume, Lester M. Salamon writes that "Homelessness among children and youth is too serious a problem to be ignored in our national social policy. Both for its immediate effects on those who are homeless, and for the inadequacies it reveals in our social support systems, homelessness among children and youth has truly become a national tragedy. If this book helps to bring this problem to national attention, to document its scope and consequences, and to point the way toward possible solutions, it will have amply served its purpose." Based on a conference sponsored by The Johns Hopkins University Institute for Policy Studies last year, this volume brings together some of the best research and policy analysis ever assembled on this important issue. Among the contributors are Lisa Mihaly, Marjorie J. Robertson, James D. Wright, Yvonne Rafferty, Kay Young McChesney, Chester Hartman, Michael A. Stegman, Linda A. Wolf, and Carol W. Williams. The volume covers issues from the scope of child homelessness to its broader impacts and causes and the social responses needed to copy with it. The volume focuses on two populations with differing needs and solutions: very young children (infants, pre-schoolers, and school age children) who are part of homeless families, and older young people who are homeless but on their own (pregnant teens and teen parents, runaways, and older adolescents). Central to the volume is a critical examination of the health, mental health, developmental and educational impacts produced by homelessness; causes of the problem in society, the economy, and our housing market, and the levels of existing support systems. In short, this is a comprehensive state-of-the-art examination of homelessness as it affects children, and will be greeted as such by policy-makers at all levels of government and by professionals in economics, sociology, social work, and urban studies.
