The differences of ICT by years surveys can be compared. Nevertheless, it may happen that the wording of a question is slightly modified. The evolution of adjustment methods may affect certain developments at the margin.

As for comparisons with ICT surveys  in enterprises with less than 10 persons employed, in addition to the differences in scope, the user should also pay attention to the time difference with the chosen ICT vintage, depending on the modules of the questionnaire he is interested in.

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. The latest ICT-VSE survey covers 2016 data.
