Attention deficit hyperactivity disorder, commonly called ADHD, affects millions of children and adults across the United States. Understanding how many people have ADHD in the US helps highlight the need for better diagnosis, support, and treatment options.
Below is a snapshot of ADHD prevalence, diagnosis rates, and treatment trends in the United States based on the latest national data available.
| Metric | 2016 | 2020 | 2023 |
|---|---|---|---|

Prevalence of ADHD Across Age Groups in the US
ADHD is often associated with children, but it also affects a significant number of adolescents and adults. The condition can continue into adulthood, and many adults remain undiagnosed.
Among children and teens, prevalence has steadily increased over the past decade. This trend reflects better recognition among parents, teachers, and clinicians. Adults with ADHD may experience challenges at work, in relationships, and in daily routines that prompt evaluation and treatment.
Diagnosis Rates by Gender and Race
Diagnosis patterns vary across gender and racial groups, which can reflect differences in access to care, cultural attitudes, and how symptoms present.
Boys are still identified with ADHD more frequently than girls, though the gap is narrowing. White children tend to have higher diagnosis rates compared with Black, Hispanic, and Asian children, though awareness and advocacy are reducing these disparities over time.
Treatment Approaches and Medication Use
Treatments for ADHD typically include medication, behavioral therapy, coaching, and educational or workplace accommodations. Medication is the most common approach, especially among school-age children, but many people benefit from a combination of strategies.
Access to therapy and consistent medication management remains unequal across regions and income levels. Telehealth expansion has improved access for many families, though not all communities benefit equally.
State-Level Differences in ADHD Identification
ADHD diagnosis rates do not appear evenly across the United States. Some states report higher percentages of children with diagnosed ADHD, which may be linked to healthcare policies, provider availability, and school-based screening programs.
These differences can also reflect variations in diagnostic criteria or in families’ ability to seek evaluations. States with stronger school-based health programs often identify more cases early and connect families with services.
Moving Forward with ADHD Awareness and Care
As understanding of ADHD grows, communities can support better identification, treatment, and accommodations.
- Promote awareness of ADHD symptoms in children and adults
- Support early screening in schools and primary care
- Expand access to culturally responsive care
- Encourage workplace and school accommodations
- Invest in training for clinicians and educators
