What the numbers show

Michigan’s 1,839,787 companies place it 10th nationally, 2.8% of the U.S. total. Activity clusters in its largest metros — Detroit, Grand Rapids and Southfield alone account for 14.2% of the state’s companies — while industrial & mechanical is the dominant sector at 28.7%. For buyers and sellers, that means the deepest pools of suppliers and manufacturers sit in a handful of cities and one or two sectors; the charts above link straight into each so you can shortlist by capability and region.
