Keep the following in mind before doing the SCCA demographic survey you may have received in your email.
1) Before you click on that link to do the SCCA survey you got in your email, know that this year, you are required to answer all questions. Not all people want to answer some of the personal ones (e.g. income, age, etc).
2)Furthermore, the survey email gives you a "unique link". In surveymonkey (the vendor they are using), by using the unique link, they actually collect the specific recipient's data (ie. your data is not anonymous).
As a result of the above two reasons (especially #2), I am not completing the questionnaire.
BTW, here is the link to survey monkey explaining anonymous vs. non-anonymous surveys:
(note the 3rd bullet: "Anyone using the email invitation collector could potentially track an email address on the response."
