Follow link below for chart data.

[text version]

Chart created by the NIDCD Epidemiology and Statistics Program.

This figure displays the prevalence (in percent) of stuttering, as determined by an examiner, in young African American (black) and European American (white) boys and girls in Illinois. There are no overall statistically significant differences in prevalence between the black and white children, although other reports have found a tendency for higher prevalence of stuttering in black children. Boys were much more likely to have increased prevalence of stuttering (at least double the rates shown for girls) for both black and white children. For these 3- to 5-year-old children, the prevalence of stuttering did not increase or decrease significantly.
