What is a requirement for respondents when additional survey questions are displayed based on demographic criteria?

When additional survey questions are displayed based on demographic criteria, it is important for respondents to meet specific attributes that align with the survey's targeted audience or research goal. By requiring that their income meets a specified threshold, the survey ensures that the responses it collects are relevant and appropriate for the demographic criteria being examined. This approach helps create a more tailored and focused analysis, as the survey can gather insights from individuals who have conditions or experiences that fit the intended demographic profile being studied.

For example, if a survey is aimed at understanding the purchasing behavior of high-income households, effectively filtering respondents based on their income ensures that the data collected reflects the opinions and behaviors of that specific group. This leads to more meaningful insights and actionable results.

Other criteria, such as age, being a current customer, or having submitted previous survey responses, may serve different purposes but do not directly tie into the demographic filtering designed to enhance the relevance of additional questions in this context.
