The survey is conducted every quarter but not all questions are asked every quarter.
In practice, two models of questionnaires were created to take into account these
specificities:
- the first questionnaire corresponds to the months of January and July;
- the second one is sent in April.
- Questionnaire 2021 for the months of January and July (pdf, fr, 616 Ko, 12/10/2021)

The balances of opinion on the half-yearly evolution of investments are published as gross series and seasonally adjusted series. The other balances are annual; they are therefore not seasonally adjusted.
