Thanks for the link. These numbers get you close, but only with women, not minorities. Also, we need the new certificates issued based on gender. If we knew how many newly minted pilots were out there, and their ratio, we could compare that to the numbers seen in new-hire classes, and get an idea what is going on. The total numbers break down to about 6% of all commercial pilots are women, about 3.5% of all ATP's are women. Compare that to what you see at your place of employment. Also keep in mind that more and more women are getting into aviation, so that means that the ratio will show more of the older, more qualified pilots are mostly men. What we actually need are employment numbers. I don't know of anyone keeping track of that, or the numbers of people who quit flying by choice. I know that where I work, 16% of the F.O.s are women. And that is in Alaska where women are hard to come by! Maybe someone sees a bias against women in hiring, but the numbers don't reflect that from what I see in my little corner of the world.
