This grouping was relevant before NAF Rév. 2 was in force (before 2008).
These activities correspond to the code EN of the NES classification :
- post and telecommunications ;
- consultancy and assistance ;
- operational services ;
- research and development.
As the INSEE classifies market services according to their main user, telecommunication services, legal services, control services and technical analyses etc. are services to businesses that are partially consumed by households.Since the introduction of NAF rev. 2, this grouping of activities no longer applies.
