21. Shreveport, Louisiana

Three out of ten people in Shreveport live below the poverty line and because of this, crime rates have soared to double the state numbers. It may be of note that instead of people choosing to move to Shreveport to settle there, residents have opted to leave the city in search of better opportunities elsewhere. In the last five years alone, the number of people living in the city decreased despite the US population growing by almost 4%.
