I’m confused. Is stuttering common as people say it is or is it rare? This is my experience, but I heard stuff from lots of other stutterers similar to this too. I stuttered since I was five I’m pretty sure. All my elementary years I NEVER met another kid who stutter, not even in speech therapy as the kids there were there for different reasons like having trouble pronouncing words, Rhoactism, etc. I’m pretty sure I was the only stutterer in elementary, and that confused me because stuttering is supposed to be like REALLY common in kids. I’m fourteen now in highschool. I STILL have NEVER met another kid who stutter. Only met two people: One of my uncles and a teacher of mine, but she outgrew hers. Kids get shocked when they hear me and they have told me I was the first stutterer they have heard of in their lives. Still haven’t met any kids in speech therapy. And then kids get confused of why am I talking like that because they don’t even know about stuttering. My experience. For something that’s supposed to be 1 out of 100, it took awfully years to find another stutterer, for them to outgrow there’s. And my uncles is a mild one too. I’m a moderate-severe one. And don’t forget that a large majority of the stuttering population are people with mild stutterers or some that aren’t even noticeable at all. Yes I know that in the USA when you find out that an estimated 3 million people stutter might seem common, but then I thought about it and New York City has a population of I’m pretty sure eight 8 million or 19 million, and Texas has a population of 30.5 million, and I heard there are only 600,000 stutterers there. In total about 300 million people live in the USA. 3 million seems like a small amount and remember a large majority of stutterers are mild. Then in Great Britain about 66 million (or more) people live there, I heard only 600,000 stutterers are there. So is stuttering common or a bit rare?
