What percentage of children are affected by hyperactivity according to research?

The correct percentage of children affected by hyperactivity according to research is typically around 3%. This figure aligns with estimates for Attention-Deficit/Hyperactivity Disorder (ADHD), which indicate that approximately 3-5% of school-age children are diagnosed with this condition. Hyperactivity is one of the key characteristics often observed in children with ADHD, and the prevalence rates are generally well-established in the field of developmental psychology.

While options like 0.03% or 0.3% suggest extremely low rates that would not be reflective of current research findings, the figure of 3% captures the reality of how common hyperactivity is in the pediatric population. This highlights the growth in awareness and diagnosis of ADHD over the years, leading to more accurate and definitive estimates.
