The stuttering prevalence ranges from 0.33% all the way up to 5.6%. Do I think it's either of those two extremes? No. Then if we are talking about incidence (the number of new cases) then the number goes even higher, from 5% all the way up to 17.7%. Here's a review: [https://pmc.ncbi.nlm.nih.gov/articles/PMC3687212/](https://pmc.ncbi.nlm.nih.gov/articles/PMC3687212/) Additionally, the review states that family history has been reported in 71% of cases, so you cannot remove that component to suit what you want to find. **This is the bottom line:** The prevalence rate of stuttering is the same or perhaps more than a disorder like schizophrenia. Schizophrenia has thousands of researchers, and millions of dollars going into its mechanisms and finding treatments for it. The prevalence is not what is holding stuttering research back, it's the sense of urgency. It begins with us. Who's going to advocate for us more than us? Nobody. If you have accepted your stutter, that's fine, you do you. I'm talking to the people that want to understand more about stuttering to hopefully find treatment strategies for it. Here's a study on the prevalence of schizophrenia: [https://www.nature.com/articles/s41380-023-02138-4](https://www.nature.com/articles/s41380-023-02138-4)
