While much has been written about the decline of central cities, very little research has examined the problem in their suburbs. This report focuses on the suburbs of older industrial cities and how best to address the challenges they face. Using census data, literature review, and four in-depth case studies, the authors provide a detailed portrait of the underlying forces shaping distressed suburbs. It highlights a range of best practices used in case study cities for fostering growth and reducing poverty. These lessons can be instructive both to local leaders working to turn their cities around and to the federal policy makers supporting them.
