The Legislature has often written laws for Detroit by specifying municipalities with a population greater than 750,000. According to the 2010 Census, Detroit no longer has 750,000 residents. The next legislative target will be 500,000 people.

In May 2011, the State Legislature's Tax Policy Committee delayed action on bills that would revise that number at the request of AT&T over claims it is owed money by the city.

Laws need to be changed by July 1, 2011 in order for the city to continue collecting a higher income tax of 2.5% for residents and 1.25% for non-residents, as well as the 5% tax on utilities and telecom services. In June 2011, the State House approved a bill extending this tax to cities with populations of 600,000 or higher.
