1. Detroit, Michigan

The worst and most dangerous city to live in in the whole of the United States, Detroit’s crash from a once industrial city to where it is now, is a sad story of urban decline. Home to almost 1.8 million residents at the peak of the car making industry in the US in the 50s, it is now home to 2/3 of half of its former numbers. The closure and downsizing of many of the job-providing assembly plants have left many unemployed and have triggered the migration of workers away from the once bustling city.
