In your personal experience, do you find the "1% of the population has a stutter" to be a bit overblown?

In your personal experience, do you find the "1% of the population has a stutter" to be a bit overblown? I'm 28 and I have met 3 people who stutter in my entire life. I can only recall 2 actually, but I'm sensing there was a 3rd somewhere along the way I'm forgetting. And none in primary school, high school, university, going by oral exams and presentations. It seems like it comes from an old study done in God knows when and everyone just runs with it.
