Data and Statistics

There are various sources for statistical information on ADHD. They include national surveys conducted by the Centers for Disease Control and Prevention (CDC), such as the National Survey of Children’s Health (NSCH) and the National Health Interview Survey (NHIS). Other governmental and non-governmental organizations such as the World Health Organization also provide reliable statistics. Prevalence studies conducted by researchers generate much useful data, as do the healthcare industry’s analysis of prescription drug costs and use. Statistics from several sources are presented here under these categories:

  • General Prevalence
  • Coexisting Conditions
  • Long-Term Outcomes
  • Treatment Data
  • Other Data including adoption, driving, diversion, hereditary risk, prison populations and suicide risk

When analyzing the results of prevalence studies, you may want to take into consideration the sample size; the population being surveyed—whether they are clinicians, parents, teachers, children, adults or a combination of these groups; the questions being asked; and the conclusions of the study.
