This book synthesizes research undertaken over a number of years by the Brookings Institution as part of its Metropolitan Opportunity series, and funded inter alia by the Ford and Annie E. Casey Foundations. It is intended to make a serious and substantial contribution to public policy debates in North America about the changing nature of poverty, in particular its spatial manifestation, and what might be done about it. In this respect, it follows in the long tradition of excellent work coming out of the Institution and supported by Foundations such as these. But the book also sets out to provide a much-needed update on the more recent causes and spatial patterns of poverty in America and to highlight the significance of more recent processes of suburbanizing poverty. Kneebone and Berube have achieved their goal of bringing together in a clear and accessible form a rigorous analysis of the new dynamics of American poverty and its increasing concentration in suburban areas rather than the traditional foci of inner city areas and more remote rural communities.
