Overview
A review of 102 studies estimated ADHD's worldwide prevalence in people under the age of 19 to be 5.29%. 10% of males, and 4% of females have been diagnosed in the U.S.[1]
Prevalance
A review of 102 studies estimated ADHD's worldwide prevalence in people under the age of 19 to be 5.29%. There was wide variability in prevalence estimates, mostly due to the methodological characteristics of studies (for example, diagnostic criteria used) and, to a lesser extent, geographic location (North America having a significantly higher rate of ADHD than Africa and the Middle East).[2]
Gender
10% of males, and (only) 4% of females have been diagnosed in the U.S.[3] This apparent sex difference may reflect either a difference in susceptibility or that females with ADHD are less likely to be diagnosed than males.[4][5]
