well based on personal observation wrt to pilots, in general, although I know of many pilots of all races...in fact I know of a part 61/91 operation that has perhaps 50% minority pilots, or even more---it's a good mixture...the biggest problem, I see is that flying is thought of ignorantly, by many Blacks' as a 'White people's thing'....
wrt to finances, well in the US they have avaition in high schools, I don't know why they think this way, but it is prevalent, so as a result, you have fewer Black pilots
this mode of thinking prevails much less so, it seems, amongst Latinos ---just an observation...call me racist if you'd like
final answer: many more White pilots!
