Licence Ouverte / Open Licence 2.0 (Etalab), source INSEE. Counts are of active companies in the Sirene register stock dated 1 November 2026: commercial companies (SARL, SAS, SA and the like) and civil companies such as SCI property companies. Sole traders, associations and public bodies are not counted, and the register lists dormant holding and property companies as active, so a count is of companies on the register, not of trading businesses. A company is counted under its main activity (NAF rev. 2 code) and the commune of its head office; companies whose register entry holds no NAF rev. 2 code are in the totals only. "With employees" means the register holds an employee band of one or more. Industry titles are English renderings of the INSEE labels. Contains data from INSEE, reused under the Licence Ouverte 2.0.
