1 out of 100

1 out of 100 Is it really true that every 1 out of 100 people has a stutter, or, if you want, 1% of the entire population? I'm currently in school, and I believe that I've met around 500 people (excluding random people from everyday encounters), and there is only one guy who says he has a stutter (I've never seen him stutter). So my question is, is this rumor so-called true, and how many people who stutter have you actually met (excluding stutter support groups, ofc)
