The following is a simplistic wild guess.
Accord to SHARE: "SHARE serves more than 20,000 individuals representing
over 2,000 of IBM's top enterprise computing customers."
What percent of the SHARE members have IBM mainframes? 90%? That would be
1,800 share members w/MFs.
What percent of the world's companies with IBM mainframes are SHARE members?
10%? That would be 18,000 companies w/MFs world-wide.
On average, 10 individuals per company.
What percent of those individuals are mainframe systems programmers? 50%?
That would be 90,000 sysprogs world-wide.
What percent are z/OS? 25% That would be 22,500 z/OS sysprogs
world-wide.
What percent are z/VM? 25% That would be 22,500 z/VM sysprogs
world-wide.
What percent are z/Linux? 25% That would be 22,500 z/Linux sysprogs
world-wide.
etc.
18,000 companies w/MFs world-wide? Seems low.
