What the numbers show

Arizona’s 1,846,881 companies place it 8th nationally, 2.9% of the U.S. total. Activity clusters in its largest metros — Phoenix, Scottsdale and Tucson alone account for 47.2% of the state’s companies — while industrial & mechanical is the dominant sector at 28.0%. 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.
