What the numbers show

Ohio’s 1,487,393 companies place it 13th nationally, 2.3% of the U.S. total. Activity clusters in its largest metros — Columbus, Cincinnati and Cleveland alone account for 23.9% of the state’s companies — while industrial & mechanical is the dominant sector at 27.1%. 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.
