Activity clusters in its largest metros — Wilmington, Dover and Newark alone account for 61.9% of the state’s companies — while industrial & mechanical is the dominant sector at 30.4%. 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.
