Manufacturing in Michigan has always been a bellwether for the health of the industrial U.S. In many ways, Michigan arose as a manufacturing state. While hunting and trapping were pre-eminent during its time as part of the Northwest Territories, logging slowly grew after statehood in 1837. Cheap and plentiful lumber attracted manufacturers, and industry drove a booming economy as the state took a lead role in the industrial revolution of the late 19th and early 20th centuries. Manufacturing grew rapidly into the 1970s.
