1970s and decline

In November 1973, the city elected Coleman Young as its first black mayor. After taking office, Young emphasized increasing racial diversity in the police department, which was predominantly white. Young also worked to improve Detroit's transportation system, but the tension between Young and his suburban counterparts over regional matters was problematic throughout his mayoral term.

In 1976, the federal government offered $600 million (~$ 2.5 billion in 2023) for building a regional rapid transit system, under a single regional authority. But the inability of Detroit and its suburban neighbors to solve conflicts over transit planning resulted in the region losing the majority of funding for rapid transit. The city then moved forward with construction of the elevated downtown circulator portion of the system, which became known as the Detroit People Mover.

The gasoline crises of 1973 and 1979 affected auto industry. Buyers chose smaller, more fuel-efficient cars made by foreign makers as the price of gas rose. Efforts to revive the city were stymied by the struggles of the auto industry, as their sales and market share declined. Automakers laid off thousands of employees and closed plants in the city, further eroding the tax base. To counteract this, the city used eminent domain to build two large new auto assembly plants in the city.

Young sought to revive the city by seeking to increase investment in the city's declining downtown. The Renaissance Center, a mixed-use office and retail complex, opened in 1977. This group of skyscrapers was an attempt to keep businesses in downtown. Young also gave city support to other large developments to attract middle and upper-class residents back to the city. Despite the Renaissance Center and other projects, the downtown area continued to lose businesses to the automobile-dependent suburbs. Major stores and hotels closed, and many large office buildings went vacant. Young was criticized for being too focused on downtown development and not doing enough to lower the city's high crime rate and improve city services to residents.

High unemployment was compounded by middle-class flight to the suburbs, and some residents leaving the state to find work. The result for the city was a higher proportion of poor in its population, reduced tax base, depressed property values, abandoned buildings, abandoned neighborhoods, and high crime rates.

On August 16, 1987, Northwest Airlines Flight 255 crashed near Detroit Metro airport, killing all but one of the 155 people on board, as well as two people on the ground.

In 1993, Young retired as Detroit's longest-serving mayor, deciding not to seek a sixth term, with Dennis Archer succeeding him. Archer prioritized downtown development, easing tensions with its suburban neighbors. A referendum to allow casino gambling in the city passed in 1996; several temporary casino facilities opened in 1999, and permanent downtown casinos with hotels opened in 2007–08.
