Who Is Affected by Stuttering

About 5% of children stutter for 6 months or more.1 Stuttering most commonly begins around age 5 but generally occurs any time between ages 2 and 7.2 About 75 out of 100 children who stutter get better without treatment.1 Boys are more likely than girls to keep stuttering.1

Those with persistent speech problems have developmental stuttering. Approximately 1% of adolescents are affected by developmental stuttering.3 This figure drops to approximately 0.8% by adulthood.2
