The survey does not feature a sampling plan: it exhaustively covers networks with more than seven retail outlets.

The retail outlets have different forms, depending on the network's business sector: agencies (real-estate, temping, etc.), salons (hairdressing, beauty), establishments (hotels, restaurants), etc.

Accordingly, a database listing the networks (and network heads) has been produced based on various sources, including both internal INSEE sources (annual business survey of service companies) and external sources (trade publications, company websites), etc.

400 companies at the head of one or more networks were surveyed, representing a total of 450 different networks.
