My recent article on the dramatic 67% increase in low-income people living in the suburbs from 2000-2011---“As Cities Prosper, Poor People Relocate to Suburbs,” May 21----was based on a newly-released Brookings Institution report. Community Development leader Joe Kriesberg has now written a piece for the National Housing Institute (NHI) questioning one of the report’s key assumptions. Noting that Brookings defined "suburb" “as any municipality with less than 100,000 people, regardless of its wealth, density, housing stock, or anything else, ” Kriesberg argues that this means that “wealthy communities with mostly single family homes can be considered ‘urban’ while dense, poor cities with significant rental housing can be considered ‘suburbs’.” Kriesberg shares my conclusion that new funding is essential to address both urban and suburban poverty, and his article, “More Suburban Poor? Think Again” is definitely worth reading.
