Got me wondering how representative the ScubaBoard membership actually is compared to the overall population of divers.
There are different ways to look at this that come to mind.
1.) Overall population of divers = # certified divers who have not quit diving entirely.
Problem: The instructor who does a hundred dives/day, & leads dive club trips to dive resorts & live-aboards, is counted the same as the OW-cert.'d vacation diver who dives 2 or 4 tanks on a cruise every other year.
2.) Overall population of
dives. So if an instructor does 200 dives/year, he counts 5 times what I do at 40, and I count 20 times the 2 dives/year on a cruise guy.
3.) Magnitude of Expenditure (I made that term up). You judge based on what people spend, either personally or in terms of where they control what others spend. So that instructor who does 200 dives/year
and decides which resorts the dive club of 20 will hit this year counts for a lot. People often speak of the wife/mother in a family making a lot of the purchasing decisions, so marketing might target her the most. Similarly, are we most interesting in divers, avid divers, professional divers who influence their students, dive shop owners who decide what gear lines to stock & rent, etc...?
