What is the estimated prevalence of ADHD in the population?

The estimated prevalence of ADHD in the population is generally recognized to be within the range of 3 to 7 percent. This estimate is supported by numerous studies and meta-analyses that survey children and adolescents, highlighting that ADHD occurs in a significant portion of the population but is not overly common. The broad range reflects variations in diagnostic criteria, age groups studied, and cultural factors that can influence identification rates.

Considering the other options, the lower estimates (1 to 2 percent) do not capture the true prevalence as noted in current research, which demonstrates a higher occurrence rate. The higher estimates (8 to 12 percent and 10 to 15 percent) may reflect specific populations or contexts where ADHD might be more frequently diagnosed or recognized, yet these figures exceed the broader epidemiological consensus based on extensive population-based studies. Thus, the 3 to 7 percent range captures the most accurate and widely accepted understanding of ADHD prevalence in the general population.
