Aaarrgggg....

AOPA & IAOPA would cover some of that.
FAA (if you can dig through the info) will also have a lot of that for the US.

AOPA did not (yes, I'm a member, and called and talked to a "stats guy").
FAA and DOT sites have lots of info but I could not locate the info I asked for above...

Thanks in advance for any sources!
