What the numbers show

Maryland’s 1,466,919 companies place it 14th nationally, 2.3% of the U.S. total. Activity clusters in its largest metros — Baltimore, Silver Spring and Rockville alone account for 21.7% of the state’s companies — while industrial & mechanical is the dominant sector at 31.6%. 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.
