Chart created by the NIDCD Epidemiology and Statistics Program.
This figure displays the prevalence (in percent) of stuttering, stammering, or other speech problem during the past 12 months for children aged 3 to 17 years, based on parent's report that a doctor or other health care professional had identified the condition. There was a marked overall decline in the prevalence of stuttering or other speech problems from the youngest age group (3 to 5 years) to the oldest (15 to 17 years). As shown in the previous figure, male children were more than twice as likely to have stuttering or other speech problems, at least for children 3 to 14 years of age. At age 15 to 17 years, males were only slightly more likely than females to have reported stuttering or other speech problems.
