What the numbers show

Washington’s 1,614,549 companies place it 11th nationally, 2.5% of the U.S. total. Activity clusters in its largest metros — Seattle, Spokane and Vancouver alone account for 26.9% of the state’s companies — while industrial & mechanical is the dominant sector at 28.5%. 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.
