42. Hammond, Indiana

Environmental damage is an issue catching up with a number of US cities, Hammond included. Citizens have started having problems with air and water pollution as well as lead contamination, mainly due to the industrial nature of the town.

As a result, people have moved onto greener pastures (literally), and the total population has decreased by over 6% in the past decade. Of those remaining in the Indiana city, over 20% live in poverty.
