The city of Detroit, Michigan, filed for Chapter 9 bankruptcy on July 18, 2013. It is the largest municipal bankruptcy filing in U.S. history by debt, estimated at $18–20 billion, exceeding Jefferson County, Alabama's $4-billion filing in 2011. Detroit is also the largest city by population in U.S. history to file for Chapter 9 bankruptcy, more than twice as large as Stockton, California, which filed in 2012. While Detroit's population had declined from a peak of 1.8 million in 1950, its July 2013 population was reported by The New York Times as a city of 700,000.
