Toledo
Ohio is another Rust Belt state going through economic turmoil, much of it tied to the auto industry. More than 368,000 have left the state than moved in during the last decade.
The Buckeye State's worst year was also 2006, when 45,000 more people left than arrived. Since that year unemployment has worsened -- it stood at about 10.6% in November, just over the national average -- but residents were forced to stay put. With unemployment up all over the country, out-of-work Ohioans have had to hunker down and wait for a rebound.
