OK, so I felt driven to run the numbers. According to FAA data for active pilot certificates in 2017 (and not counting student pilots), only 5% are held by women. This has been pretty much the case for three decades or more, despite the emphasis on encouraging women in aviation. With regard to pilot age, over half (51%+) are over 50.

For student pilots: Only 1/3 of student pilots are under 24; 1/3 25 to 34; so that means 1/3 of student pilots are 35+. This could indicate learning to fly comes with higher disposable income, but that middle third is also often when extra expenses for raising children come in.

Anyway, yes, we are predominantly old and overwhelmingly male. That two major divisions of EAA are led by women chosen by their membership groups (and in my opinion, led quite ably) -- and are therefore on the Board -- is noteworthy.
