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 Maine directory total; size shares use records with a known employee count. Data compiled by Factur, a sales and marketing firm for B2B manufacturers.
