What the numbers show

Delaware’s 182,448 records place it 47th nationally, 0.3% of the U.S. total, and 37th for large employers. That large-employer rank is well above its rank by records, so its business base is weighted toward bigger companies. Activity clusters in its largest metros — Wilmington, Dover and Newark alone account for 61.9% of the state’s records — and the state leans toward it, financial and communication compared with the rest of the country. For buyers and sellers, that means the deepest pools of suppliers sit in a handful of cities and sectors; the charts above link straight into each so you can shortlist by capability and region.

Methodology

Figures count records in Factur’s U.S. business directory as of July 2026, classified by city and primary industry using NAICS/SIC codes. Records cover manufacturers, suppliers and businesses of all sizes. They are not a count of unique companies: one company can have several records (for example one per department or location), and some records are duplicates. That affects large companies most, so treat raw totals as an upper bound and rely on the ranks, shares and comparisons, which it affects much less. These are directory totals, not official census figures. Percentages are computed against the Delaware directory total; size shares use records with a known employee count.
