Governments should promote the development of affordable housing in urban periphery communities. The US Department of Housing and Urban Development defines households spending more than 30 percent of their income on housing as “cost burdened” and estimates that some 12 million households spend over 50 percent of their income on housing. This problem is especially severe in the suburbs, where more Americans live below the poverty line than in the urban core. Investing in affordable housing in Urban Periphery communities can make residence in the community attractive and accessible to people who work in the metro center.
