Service groups: diverse core business activities
A quarter of the business groups included in the French business census have their core activity in the goods and services sector or the financial services sector. These groups control half the employees in these sectors: a large number of them are in the financial services sector, with a lesser number in individual services. Amongst the 4,000 service groups there is a sufficient number of businesses to have diverse activities; this is the case for half of these groups. It is often the group's core business activities that become diversified. Service sectors such as the postal service, telecommunications or sanitation, are dominated by very large groups, involved in numerous activities.
