What are you considering 'Active'? I know there are a few people that could probably give you some good ideas on how to go about actual research of this. I also think everyone would agree that it is going to be a very tough number to get. A definition on 'Active' is key in determining injuries and fatalities among 'Active' vs 'Inactive later'.
The actual number of cave dives per year would be the most beneficial number in my mind.
