The scope of the survey has changed significantly compared to the 2012 ICT-VSE, which may impact the changes observed between the two surveys. As for comparisons with ICT surveys on enterprises with 10 or more persons employed, in addition to the differences in area, the user will also have to pay attention to the time difference with the year of the ICT survey selected, depending on the modules of the questionnaire in which the user is interested.

The changes in the stratification of the sample and the correction methods can also affect certain changes.

The ICT-VSE survey data can be supplemented by the data of the ICT survey in enterprises with 10 or more persons employed, while paying careful attention to the differences in area between the two surveys.
