You are right. The study does not contain information regarding the quantity of people representing those age groups. **Is it possible to gain access to this raw data?** Answer: "*Data not already presented in this article but generated during and/or analyzed for this study are not publicly available due to the risk of identifying participants. Researchers interested in using portions of these data should contact the corresponding author.*" So, you could always try to contact Seth and Yaruss in [this](https://www.reddit.com/r/Stutter/comments/16o8l2l/participate_in_stuttering_research_exploring_the/) post, to officially request the data. Another way to find similar data on the quantity of people representing those age groups is: **Step 1**: [https://www.google.com/search?q=suicide+rate+2023+by+age](https://www.google.com/search?q=suicide+rate+2023+by+age) **Step 2**: Pick a link in the google search, such as: [https://www.cdc.gov/suicide/suicide-data-statistics.html](https://www.cdc.gov/suicide/suicide-data-statistics.html). [This](https://i.imgur.com/x4Yu6RV.png) diagram states that people in the age group of 10-24 have the least suicide rates, whereas people in the age group of 24-44 and 44-64 have the highest suicide rate.
