Detroit, the largest city in Michigan, is situated in the southeast part of the state on the Detroit River. Detroit is one of the largest manufacturing cities in the U.S. and is the center of the automobile manufacturing industry, which has experienced a decline due to foreign competition in the past decade. The health and medical care sector is important to the economy, and employment in the finance, insurance, and real-estate industries has inched up in the Detroit metropolitan area since the early 1990s.
