The economy may be on the mend from the Great Recession, but poverty is a growing problem. The percentage of Americans living in poverty rose from 12.4% in 2009 to 14.6% in 2015. As numbers culled by 24/7 Wall Street point out, it's also more common for people to be living in a neighborhood designated as one of "extreme poverty," meaning it has a poverty rate of 40% or more. Here are the 10 places where poverty is concentrating the fastest: 
 -  Bakersfield, Calif.
  -  Phoenix-Mesa-Scottsdale, Ariz.
  -  Toledo, Ohio
  -  Indianapolis-Carmel-Anderson, Ind.
  -  Fresno, Calif.
