Having this information and understanding who lives in your household allows us to select surveys that are relevant to you (or to your household).
All the factors we ask about (age, gender, profession, who lives in your household, etc) collectively figure into lifestyle, which is a major factor in determining what products and services (and related surveys) may be of interest to you and your family. For example, we send surveys about products for children (and their parents) only to members who have children in their households.
Please be assured that all the information you provide is kept confidential. For more on how we protect your information, please visit the MySurvey Privacy page.
