Since 2022, the surveyed unit have been evolved, leading to a break in series which affects time comparisions.

Some treatments may also affect time comparisions :

• change of the wording of a question ;

• evolution of adjustment methods.

Both ICT surveys on more or less than 10 persons employed can be compared, but the user has to pay attention on scope differences.

Data from the ICT survey can be supplemented by data from the ICT-VSE survey in enterprises with less than 10 persons employed, but be careful to be aware of the differences in scope between the two surveys.
