Data & Statistics
Children with ADHD
How many children have ADHD?
The percent of children estimated to have ADHD has changed over time and can vary by how it is measured. Recent surveys of parents(https://www.cdc.gov/ncbddd/adhd/features/key-findings-adhd72013.html) show that approximately 11% of children 4-17 years of age (6.4 million) have ever been diagnosed with ADHD as of 2011.
The American Psychiatric Association states in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) that 5% of children have ADHD1. However, other studies in the US have estimated higher rates in community samples.
CDC uses datasets from parent surveys and healthcare claims to understand diagnosis and treatment patterns. On this page you can see information from three different studies:
- Healthcare claims data on medication and psychological services (ages 2-5).
- Survey data on diagnosis and medication treatment (ages 4-17)
- Survey data on medication and behavior treatment (children with special health care needs ages 4-17)
Medication and Psychological Services Among Children Ages 2-5 Years (Healthcare Claims Data)
American Academy of Pediatrics (AAP) guidelines(https://www.cdc.gov/ncbddd/adhd/guidelines.html) (2011) state that behavior therapy is the recommended first line treatment for Attention-Deficit/Hyperactivity Disorder (ADHD) in young children, and should be tried before medication is prescribed. To understand treatment patterns for children ages 2-5 years receiving clinical care for ADHD, healthcare claims for psychological services and ADHD medication were compared for patients covered by MarketScan commercial employer-sponsored insurance (ESI, 2008–2014) or by Medicaid (2008–2011).
- In both ESI and Medicaid populations, the percentage of children ages 2–5 years receiving clinical care for ADHD increased over time.
- In both populations, about 3 in 4 children ages 2-5 years with ADHD received ADHD medicine, and only about half or fewer received any form of psychological services.
- During 2008–2011, 2–5 year-old children covered by Medicaid were twice as likely to receive clinical care for ADHD compared with similar-aged children covered by ESI.
- Among 2-5 year-old children with ESI, the percentage in clinical care for ADHD that received psychological services did not increase after the release of the 2011 AAP guidelines; a similar analysis was not done for children with Medicaid since data past 2011 were not available.
Medication and Behavior Treatment Among Children Ages 4-17 Years (Survey Data)
The data from a national sample of children with special health care needs, ages 4-17 years, collected in 2009-10, showed that most children with ADHD received either medication treatment or behavior therapy; however, many were not receiving treatment as described in the best practice guidelines from 2011.
- Less than 1 in 3 children with ADHD received both medication treatment and behavior therapy, the preferred treatment approach for children ages 6 and older.
- Only half of preschoolers (4-5 years of age) with ADHD received behavior therapy, which is now the recommended first-line treatment for this group.
- About half of preschoolers with ADHD were taking medication for ADHD, and about 1 in 4 were treated only with medication.
ADHD medication and behavior therapy among children with ADHD (ages 4-17) with special health care needs
Data are from the National Survey of Children with Special Health Care Needs, collected in 2009-2010. Parents were asked about their child’s ADHD medication use in the previous week and about behavior therapy in the previous year.

Diagnosis and Medication Treatment Among Children Ages 4-17 Years (Survey Data)
- Recent surveys asked parents whether their child received an ADHD diagnosis from a health care provider. The results show that:
- Approximately 11% of children 4-17 years of age (6.4 million) have ever been diagnosed with ADHD as of 2011.
- The percentage of children with an ADHD diagnosis continues to increase, from 7.8% in 2003 to 9.5% in 2007 and to 11.0% in 2011.
- Rates of ADHD diagnosis increased an average of 3% per year from 1997 to 2006 [Read article] and an average of approximately 5% per year from 2003 to 2011.
- Boys (13.2%) were more likely than girls (5.6%) to have ever been diagnosed with ADHD.
- The average age of ADHD diagnosis was 7 years of age, but children reported by their parents as having more severe ADHD were diagnosed earlier.
- Prevalence of ADHD diagnosis varied substantially by state, from a low of 5.6% in Nevada to a high of 18.7% in Kentucky.
State-based Prevalence Data of ADHD Diagnosis (2011-2012)
Parents were also asked about whether their child was taking medication for ADHD. The results show that:
- The prevalence of children 4-17 years of age taking ADHD medication increased from 4.8% in 2007 to 6.1% in 2011
- More US children were receiving ADHD treatment in 2011 compared to 2007; however, as many as 17.5% of children with current ADHD were not receiving either medication for ADHD or mental health counseling in 2011.
- In 2011, geographic variability in the percent of children taking medication for ADHD ranged from a low of 2% in Nevada to a high of 10.4% in Louisiana.
