These are raw numbers. While they may not provide details, they do present some interesting pieces of information. Much of the information you suggested is not readily available. Fleet sizes change for year to year, a wide variety of operations are conducted, a large variation for fleet usage, occupancy may not be accurately recorded and so on makes that sort of information difficult if not impossible to figure.
But some of the raw data points out some eye opening figures.
The R44 has twice the fatality rate of the R22.
The BH206 and the AStar have an above average fatality rate, even though they are primarily professionally flown.
The Hiller 12 has almost half the fatality rate of the BH47 even though both are used extensively in utility and ag work.
These numbers give you some food for thought. While much of the requested/suggested data would be nice to have, it would almost have to be done on an annual basis which would make the numbers too small and fluctuate to radically.
What is it about the type of operations they do or the design that makes for that difference?
Note that the R22, S300 and the Enstrom 28/280 are reasonably close in fatality rates. All three are heavily used as trainers. The BH206 and AStar are also fairly close in the fatality rates, but the H500 is half that of the AStar. Also similar use, charter, utility, ag, etc.
