"Studies show that recipients of Section 8 vouchers have tended to 
choose moderately poor neighborhoods that were already on the decline, 
not low-poverty neighborhoods.  One recent study publicized by HUD 
warned that policy makers should lower their expectations, because 
voucher recipients seemed not to be spreading out, as they had hoped, 
but clustering together.  Galster theorizes that every neighborhood has 
its tipping point -- a threshold well below a 40 percent poverty rate -- 
beyond which crime explodes and other severe social problems set in. 
Pushing a greater number of neighborhoods past that tipping point is 
likely to produce more total crime.  In 2003, the Brookings Institution 
published a list of the 15 cities where the number of high-poverty 
neighborhoods had declined the most.  In recent years, most of those 
cities have also shown up as among the most violent in the U.S., 
according to FBI data."
