A small segment of a small segment. Anecdotally, I know three southpaws that play lefthanded. I know more than that who play righthanded, because it was easier to learn to play that way. Cheaper too. As for "programmes", they don't want to warehouse stuff. So if, they do not have an immediate need, they don't want it. I was able to donate a drum kit through a friend of a friend, but there was someone who could use it.
According to Fender, 07% of the population is at least a beginner guitarist. Some one who at least picked up a guitar and tried to learn how to play it.
So, 07% of the population. Lefties are 10% of the population. Lefties who play standard guitars are, say, 70% of the population. So- guitar players who are starting out are fewer in number than the people who play. We skew older, so we have our own gear.
So. let's be kind and say 60% have no need.
40% of 30% of 10% of 7%, 90% who give up. So, with a population of 336M, you have 23.5M According to Fender, 90% of that 7% quit in the first year. 2,352,000 stick with it.. Lefties clock in at 233,520. Lefties who don't play right handed are (possibly), 70,056. of those, 42,033 *might* need a guitar. Demand was up during the recent health wonkiness, but that seems to be tailing off.
Yeah, there might be two or three that need a left-handed beginner guitar in PA, but I'm not going to hunt them down with bloodhounds.
Might be errors in the math, but math is math.
