What the numbers show

Indiana’s 962,481 companies place it 22nd nationally, 1.5% of the U.S. total. Activity clusters in its largest metros — Indianapolis, Fort Wayne and Evansville alone account for 28.2% of the state’s companies — while industrial & mechanical is the dominant sector at 28.3%. 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.
