I'm not a statistician, and I'm not sure it's possible to tease any useful information about the actual safety of cycling from this report. Granted the information is potentially useful for public health planning.
I agree with you. It's a subtle thing, but the report isn't looking at the safety of individual activities from the point of view of the participants. I know for example that I spend way more time on my floor than on my bike, so my floor is probably safer on a per hour basis.
Ok. Here's a question: If one were a public health official and wanting to reduce the quantity of head injuries, would it be sensible to choose the segment from this report having the largest quantity and to attack that segment first? Would it make sense to look at household injuries from flooring and furniture and so forth, and how to prevent those?
