The New Republic: Detroit's Collapse Shown in Maps
"The Motor City has been in decline for decades; its population peaked at 1.8 million in 1950 and declined to just 700,000 people in the last Census. Predictably, its economy faltered—especially over the last decade. The unemployment rate is over 18 percent; fewer than half of adult residents are employed. A shrinking tax base made the city’s debt unsustainable—forcing it into bankruptcy."
