This questionnaire allows you to obtain essential information about your participants (age, gender, etc.).

The various criteria assessed through this questionnaire are traditional criteria for population segmentation.

In the case where you are targeting a specific population, these indicators will help you determine if your participants are a good fit for your target sample.
These pieces of information also enable you to verify that your sample is representative of the overall population.

If you wish to study different groups of participants, socio-demographic data allows you to create your various conditions.
