The different steps of the survey ensure that the process meets the requirements for statistical production:
- test of the questionnaire prior to collection
- stratified sample selection
- reminders and checks of data being collected
- clearance
- adjustment of total non-response
- shimming
- adjustment for partial non-response
- compliance notice issued by the Label Committee.

Total non-response is adjusted by reweighting the responding units after calculating homogeneous response groups and partial non-response using hot-deck methods.
Units with a partial non-response rate above a certain threshold (often 80%) are referred to as non-respondents. Some so-called "non-substitutable" units may be treated separately, because of their atypical behaviour and the influence they may have on the results.
The calculation of confidence intervals of the results will also be performed.
