I believe the concern is that the sample of respondents is not random, and indeed, not really representative of any particular population. Thus, the data reflects the bias not of the population of that specific area alone but also the channels via which this program is disseminated.

Also self reported data is often flawed in and of itself

Oh for sure. I get that. My own bias showed even though I tried not to.

Maybe so, but that’s not the entirety of the issue here.

The other main problems are sampling bias (ie, the survey is sent to folks who are not representative of the broader population), and non-response bias (ie, the types of people who elect to respond to such a survey are not representative of the broader population).
