I am skeptical.
I did the survey - but as always, many of the questions seemed stupid to me, so I did what every normal person (well MY normal) would do: I got offended and then lied. A Lot!
For example: "I often crave adventure" is a meaningless question. One of my coworkers thinks this means ordering the "spicy" tacos at Taco Bell every other thursday for lunch (but not too much adventure!). Another person I know perceives this as sledging their way on foot to the north pole with a group of disabled veterans in order to raise money for a charity. Same question. Very different responses.
I have personally participated in all of the activities listed more than once. Twice for some of them. Tens of times for others. Hundreds of times for others. Thousands of times for some physical activities not listed...(the survey missed Hockey, Baseball & Football! AND the other football: soccer) Seems to indicate that this question is just random data collection.
The age brackets seems to lump all "young" people together and all "old" people together... Makes assumptions that only middle aged people are targets. Let's ignore the young and the old?
The "race" question seems totally random (or at the very least extremely narrow minded mid stream bland American centric...). A quick survey of the 20 people I work closest with gives 1 white, 19 "none of the above" (unless "Other or multiple races" is the catch all for my "none of the above").

But it was fun. A bit.

P.S. IMHO, Scubaboarders are NOT representative of divers. Scubaboarders are the core fanatics (with a healthy sprinkling of the lunatic fringe included). I suggest 9 out of 10 divers have never heard of Scubaboard. As proof I see way too many split fins, snorkels & Spare Airs and ZERO BP's, SMB's or doubles on my dive trips.
ymmv...
