It is where cop Axel Foley is from, notorious for its poverty and crime as well as its cultural history.
Detroit was founded on July 24, 1701, by the French explorer and adventurer Antoine Laumet de La Mothe, sieur de Cadillac. The Detroit area emerged as a significant metropolitan region within the United States as construction of a regional freeway system was completed in the 1950s and 1960s. With these commuting ties allowing social and economic integration across a larger area, the Detroit name sometimes refers to the three-county Urban Area (population 3,734,090, area of 1,337 square miles (3,460 km2), as of the 2010 United States Census), the six-county Metropolitan Statistical Area (2010 Census population of 4,296,250, area of 3,913 square miles [10,130 km2]), or the nine-county Combined Statistical Area (2010 Census population of 5,218,852, area of 5,814 square miles [15,060 km2]). The Detroit–Windsor area, a commercial link straddling the Canada–U.S. border, has a total population of about 5,700,000. The Detroit metropolitan region currently holds roughly one-half of the state's population. "Detroit" is a metonym for the American automobile industry and an important source of popular music legacies celebrated by the city's two familiar nicknames, the Motor City and Motown. Other nicknames arose in the 20th century, including City of Champions beginning in the 1930s for its successes in individual and team sport, The D, Hockeytown (a trademark owned by the city's NHL club, the Red Wings), Rock City (after the Kiss song "Detroit Rock City"), and The 313 (its telephone area code). Detroit's auto industry was an important element of the American "Arsenal of Democracy" supporting the Allied powers during World War II.
Between 2000 and 2010 the city's population fell by 25 percent, changing its ranking from the nation's 10th largest city to 18th. In 2010, the city had a population of 713,777, more than a 60 percent drop down from a peak population of over 1.8 million at the 1950 census, indicating a serious and long-running decline of Detroit's economic strength. Commensurate with the shift of population and jobs to its suburbs or other states, the city has had to adjust its role within the larger metropolitan area. Downtown Detroit has seen an increased role as an entertainment hub in the 21st century, with the opening of three casinos, new stadiums, and a riverfront revitalization project. However, many neighborhoods remain distressed.
The state governor declared a financial emergency in March 2013, appointing an emergency manager. On July 18, 2013, Detroit filed the largest municipal bankruptcy case in U.S. history. It was declared bankrupt by Judge Steven W. Rhodes of the Bankruptcy Court for the Eastern District of Michigan on December 3, who cited its $18.5 billion debt and declared that negotiations with its thousands of creditors were unfeasible.
