Exploring the lessons that can be drawn from the United States's experience in providing affordable, low-cost housing, this book reviews recent developments in the US regarding such provision. Topics covered include: the changing role of the federal government; greater responsibility of state and local government; and innovative financial mechanisms. The book comprises case studies of success stories. A conclusion weaves together the strands developed in the individual case studies, examines criteria that define success, identifies common factors, and considers opportunities for developing more effective policies and programmes.
