I asked myself this question and came up with some surprising answers. I read that in 2019, there were 664,000 pilots in the US, but 197,000 of them were Student. So, only 446,000 had at least a Private Pilot Certificate. Are those numbers right? I've made it to CFII myself, but didn't think that I was in such a small group. I guess that can be right, but I'm still kinda shocked.
