      summary: Sector benchmarks by NAF activity code (medians vs peers)
      description: 'Sector benchmarks and sector statistics for a French NAF activity code (any level: division, groupe, classe, sous-classe): number of active companies, median company age (with quartiles), workforce-bracket distribution, and — when at least 5 companies file public accounts — median revenue, EBITDA margin, pre-tax result and debt ratio. Peer comparison in one call: place a company against its peers. Aggregates only, no personal data; sectors with fewer than 5 companies are excluded.'
