1% of the world population stutter, but where are they?

1% of the world population stutter, but where are they? Hello everybody! I have read that more than 70 million people in the entire world stutters (and that’s about 1% of the global population). I’m from Sweden and I have never meet someone who stutters. It would be nice to actualy meet someone who stutters in person, but I have never noticed anyone stutter like myself. Where are this 1%? Have any of you thought about this too, or is it just me?
