"An analysis by The Associated Press, based on data collected by the U.S. Postal Service and the Housing and Urban Development Department, shows the emptiest neighborhoods are clustered in places hit hard during the recession of the 1980s — cities such as Flint, Mich.; Columbus, Ohio; Buffalo, N.Y.; and Indianapolis.""In some sections of certain areas like Cincinnati's Over-the-Rhine neighborhood, roughly two of every three homes are vacant or used by squatters. The area is more than 70 percent black and poor, with unemployment often around 50 percent. It's a place where simmering resentment and frustration boiled up into three days of rioting in 2001 after police fatally shot a young, unarmed black man fleeing arrest on traffic warrants."
"In Buffalo, there are as many as 10,000 vacant, abandoned homes. Suburban sprawl, an aging population and manufacturing losses have left the city with a population under 300,000 — about half what it was during the 1950s."
