More than 100 years after the auto assembly line was first introduced, Macomb County remains at the forefront of the U.S. auto industry. The transformational growth of this industry is opening up economic opportunities across Macomb County. Ten automotive OEM facilities occupy 25 million square feet and employ more than 35,000 workers here. Since 2010, automotive companies have invested more than $7.4 billion in Macomb County including substantial investments by Fiat Chrysler Automobiles, Ford Motor Company and General Motors. 

Macomb County’s automotive supply chain network is comprised of more than 400 companies that specialize in all stages of product life cycle with significant expertise in research and development, tool and die, and automated systems.
Success in business is dependent on access to a wide and deep pool of talent and experience. Aside from more than 75,000 in the skilled trades, our region employs more than 87,000 engineers and 70,000 R&D professionals. Each year, more than 12,000 engineers graduate from Michigan universities and colleges with degrees in a wide range of disciplines. 

Macomb County is better equipped than any other county in the nation to implement next generation mobility through connected and autonomous vehicle capabilities. The infrastructure and workforce needed to support the emerging demands of this industry exist here. National labs and research facilities creating this synergy include the Ford Romeo Proving Grounds, General Motors Global Technical Center, National Automotive Center (NAC) and U.S. Army Tank Automotive Research Development and Engineering Center (TARDEC).





For generations, Macomb County's skilled and talented workforce has been a driving force in the prosperity of the mobility industry. As employment trends have highlighted an aging workforce, Macomb County has developed a number of inventive and impactful workforce development initiatives which are helping inject new talent into the auto industry.
