The number of poor people in U.S. suburbs rose by 63.6% between 2000 and 2011, from 10 million to well over 16 million people. For the first time, there are now more people living in poverty in the suburbs than in cities. In some metro areas, the number of poor people living outside the city proper has jumped even more rapidly. In the Atlanta, Ga., suburbs there are roughly 480,000 more people living below the poverty line than there were in 2000, an extraordinary 158% increase in the number of the suburban poor. Based on data collected by the Brookings Institution as part of a comprehensive study on suburban poverty, 24/7 Wall St. reviewed the 10 cities with the biggest increases in suburban poverty between 2000 and 2011.
