As far as "bad" towns, the places listed so far are limp-dick compared to these offerings:
East St. Louis, IL
Watts, CA
Camden, NJ
Gary, IN
The Bronx, NY
N. Little Rock, AR
That's just a start. Anyone who's been to these places knows what I am talking about.
I know what you are talking about Jagger, I've been to them as well. I drove through East St. Louis, IL and it is a complete shit hole! I thought I was in Haiti. Gary Indiana is just an armpit. I have a few to add to this distinguished list: Joliet-IL, Worth-IL, Hammond-IN, East Chicago-IN, they make Camden, Elizabeth and Newark look middle class [which doesn't say much].
Anyone driving on I-80 in Northwest Indiana, don't get off except to get gas.
