In Switzerland, where I live, the communities of rock climbers and ski tourers are quite overlapping. I often rock climb in sport setups (single or multi-pitch and bouldering) but almost never go ski touring because I feel it's too dangerous in a way I cannot control. I know that ski touring on gentler slopes with good conditions is rather safe, but then it's not so interesting. I'm a good amateur skier but I'd rather go to resorts, that I mildly like, because I don't want to take this risk.
I don't know whether my feeling is backed by statistics. Most websites I found on the topic are not so solid, and they mix rock climbing with high-altitude mountaineering (e.g., Climbing is the most dangerous sport there is: Look at how many people die climbing Annapurna). In the same way, they also mix ski touring with resort skiing, which is clearly much safer (avalanche risk is minimal, you may hit or be hit by someone but help comes quite fast).
My question: is there any reference that compares in a statistically sound way the dangers of rock climbing (i.e., bouldering + single pitch + multi pitch sport climbing) with those of ski touring?
