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).<ref name="Polanczyk">{{cite journal|author=Polanczyk G, de Lima MS, Horta BL, Biederman J, Rohde LA|title=The worldwide prevalence of ADHD: a systematic review and metaregression analysis|journal=Am J Psychiatry|date=2007|volume=164|issue=6|pages=942–48 |pmid=17541055|doi=10.1176/appi.ajp.164.6.942}}</ref>
