And idea how many of those Cirrus and Cessna 172 accidents involved
fatalities?

A quick look at the NTSB database reveals 85 fatalities for Cessna
172s since January 1, 2008, and 48 fatalities for Cirrus SR-22s since
that same date.

I was asking Ron for the number of accidents in his count that yielded
fatalities, not the number of fatalities for your subset.

There are 26,163 Cessna 172s registered currently, and 3,746 Cirrus
SR-22s.

As has been already pointed out to you, the registration count for
Cessna 172s does not provide any idea how many are actually in use for
any measurement period. Here is what the FAA says about their
registration records with respect to this issue:

"Of the more than 343,000 aircraft registered, an estimated 104,000, or
about one-third, are possibly no longer eligible for registration."

Now, if you are convinced that 23,000 Cessna 172s are idle and only
3000 or so are flying, and/or that all Ciruss SR-22s are flying,

Unfortunately you continue to use data sets that have already been
pointed out as unreliable basis for normalization.
