Data & Statistics


In the United States

  • The American Psychiatric Association states in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) that 5% of children have ADHD1.  However, studies in the US have estimated higher rates in community samples.
  • ADHD Throughout the Years

    Timeline of ADHD diagnostic criteria, prevalence, and treatment
  • The percent of children estimated to have ADHD has changed over time. A historical view provides the necessary context to understand changes in what we know about ADHD, including estimates of the rates of ADHD across time, changes in diagnostic criteria, and medication treatment.
  • Recent surveys asked parents whether their child received an ADHD diagnosis from a health care provider. The results show that:
    [Read Summary]
    • Approximately 11% of children 4-17 years of age (6.4 million) have 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.

Medication Treatment

[Read summary]

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.

Peer Relationships

[Read article]
 

  • Parents of children with a history of ADHD report almost 3 times as many peer problems as those without a history of ADHD (21.1% vs. 7.3%).
  • Parents report that children with a history of ADHD are almost 10 times as likely to have difficulties that interfere with friendships (20.6% vs. 2.0%).

 

Injury

  • A higher percentage of parents of children with attention-deficit/hyperactivity disorder reported non-fatal injuries (4.5% vs. 2.5% for healthy children). [Read article]
  • Children with ADHD, compared to children without ADHD, were more likely to have major injuries (59% vs. 49%), hospital inpatient (26% vs. 18%), hospital outpatient (41% vs. 33%), or emergency department admission (81% vs. 74%). [Read article]
  • Data from international samples suggest that young people with high levels of attentional difficulties are at greater risk of involvement in a motor vehicle crash, drinking and driving, and traffic violations. [Read article]

 

Economic Cost

  • Using a prevalence rate of 5%, the annual societal ‘‘cost of illness’’ for ADHD is estimated to be between $36 and $52 billion, in 2005 dollars. It is estimated to be between $12,005 and $17,458 annually per individual. [Read article]
  • There were an estimated 7 million ambulatory care visits for ADHD in 2006. [Read article]
  • The total excess cost of ADHD in the US in 2000 was $31.6 billion. Of this total, $1.6 billion was for the treatment of patients, $12.1 billion was for all other health care costs of persons with ADHD, $14.2 billion was for all other health care costs of family members with ADHD, and $3.7 billion was for the work loss cost of adults with ADHD and adult family members of persons with ADHD. [Read article]
  • ADHD creates a significant financial burden regarding the cost of medical care and work loss for patients and family members. The annual average direct cost for each per ADHD patient was $1,574, compared to $541 among matched controls. The annual average payment (direct plus indirect cost) per family member was $2,728 for non-ADHD family members of ADHD patients versus $1,440 for family members of matched controls. [Read article]
  • Across 10 countries, it was projected that ADHD was associated with 143.8 million lost days of productivity each year. Most of this loss can be attributed to ADHD and not co-occurring conditions. [Read article]
  • Workers with ADHD were more likely to have at least one sick day in the past month compared to workers without ADHD. [Read article]
