Illinois has a rich history of American manufacturing. It is the 5th largest state by GDP in the United States today and one of our most diverse state economies. Manufacturing has traditionally been the largest industry in Illinois, making up around 14% of the state’s total economic activity. A lot of that manufacturing is centered around farm machinery and auto – since Illinois is centrally located in our country, it’s an attractive spot for distribution.
