Chattanooga's bucking another trend.
A comprehensive study released Monday by the Brookings Institution showed that while poverty is increasing nationwide, it has hit suburbs harder than cities in the last dozen years.
Brookings researchers used census and other federal data to show that the number of people living in poverty in the suburbs rose by 64 percent nationwide between 2000 and 2011. That's compared to a 29 percent increase in cities.
The formula holds true for Tennessee's largest cities: Knoxville's suburban poverty rate rose 50.1 percent, compared to 15.3 percent in the city.
