Using rough numbers, the FCC say 772000 of our 330,000,000 population have ham radio licenses. Again roughly that is 1/4 of a percent of the population having a license for our hobby.
In even distribution (again roughly to keep this simple) one out of 400 people is licensed.
Yet the numbers in certain occupations appear much higher than 1 out of 400, suggesting a skew towards these professions. Science, medical, military, management, inventors all seem to be over represented.
While we easily can notice clustering where 2, 3 or 10 out of 400 in a field are licensed, it isn’t possible to tell from statistics whether our hobby developed these folk to perform higher or if the hobby just attracts higher performers.
Personal take is the hobby both attracts and develops.
Those interested in and already highly skilled or established on the path becoming highly skilled, seek out the ether and the technology, along with those whose desire to communicate are readily attracted to ham radio. You might consider them “naturals.”
And those who take up the hobby find themselves in the midst of the like minded and in a wonderland of technical possibilities that both cultivates endless opportunities for personal growth through amateur radio.
Doesn’t matter where your starting point is at your ham start
Oh, as for certain to have the people that shine there ends up being those who do not shine so very much that are the contrast. Yet these folks (mostly) are fine hams nonetheless! One observes that by proximity and close examples that those a bit behind in shining out, do advance themselves at least in terms of amateur radio. I’d consider that a validation that ham radio builds your smarts!
Some outstanding folk that have/had ham radio licenses are (taken from a recent Fond du Lac Amateur Radio Club Newsletter):
