Recreational scuba divers are not that well described. The challenge researchers face is finding a representative sample. For example, if we conduct a survey of ScubaBoard members then that might be biased towards one segment of our community, but ignore others. Same if we survey dive club members, or insured divers, or newly certified divers... Over the years, if you take all these types of studies into account, we might generally paint a picture of who we are. But, to obtain a proper snapshot we would need to randomly sample people and ask "Are you a diver?". To do this in a small village might be affordable, but to get a nationally representative sample would cost millions of dollars. And,... that is just what the CDC have done.
The CDC coordinate a year-round random telephone-based survey in every US state and, in three of the last six years, in addition to the nearly 300 questions they've asked about people's lives, they have also asked if people were active in the previous month. If so, were they most active at scuba diving? So, for what may be the first large scale random sample survey of active US scuba divers, anyone interested can download the short, two-page paper here: http://journals.sagepub.com/doi/10.1177/2047487318790290
I don't know about the rest of you, but I see more than a passing resemblance to me in these results.
