ADHD Numbers: Facts, Stats and Everything We Need To Know

Learn key statistics about ADHD; a neurodivergent condition frequently overlooked and undiagnosed.

ADHD is a Worldwide Condition

Studies show that ADHD is a condition that affects everyone in both developed and developing countries alike. The ADHD Institute reports that ADHD is experienced by up to 8.1% of the kid's population from toddlers to adolescents in the United States alone, and up to 7.3% of the entire adult population in France. [1]

This data shows a continuously increasing rate of diagnosis and increasing awareness around ADHD.

There's More Number Behind The Current Statistics

Many experts believe that there are undiagnosed cases of ADHD that we need to take into consideration. Due to the stigma associated with ADHD, we tend to overlook those who suffer from it. A study published by the Journal of Attention Disorders[2] showed that only 1 out of 10 people with ADHD were diagnosed correctly or correctly treated for their condition.

These numbers are alarming since undiagnosed or misdiagnosed ADHD still needs emotional support and a proper approach to manage their condition.

Children ADHD to Adult ADHD Statistics

According to CHADD [4], children can get diagnosed as early as 3-7 years old and continue to have symptoms when they grow older. They may still have the same issues and difficulties regarding their academics, relationships, and daily activities - even when they become adults with ADHD.

ADHD Diagnosis: 
Gender Difference

Males have a higher chance of being diagnosed with ADHD than females do. For every three men diagnosed with ADHD, only one woman is diagnosed.

However, men are more frequently diagnosed with Hyperactive ADHD than women who tend to have the Inattentive type of ADHD. Inattentive type of ADHD is the most likely to be undiagnosed, which could explain the disparity of diagnosis between men and women.

What is the Statistics for Treating ADHD?

In 2016, according to CDC[5], approximately 6 Million Children were diagnosed with ADHD, and almost two-thirds of this sample size is taking up medication related to ADHD treatment. Nearly half of them had undergone therapy sessions, including behavioral therapy and tutoring.

Is ADHD dependent on race, gender, nationality, or social class?

Studies show that ADHD is not dependent on a person's race, gender, nationality, or social class. The disorder can affect anyone and every one no matter where they're from and what their background is.

Does ADHD limits the capability of a person to learn?

Yes. ADHD can sometimes harm a child's ability to learn. It can be difficult for them to focus and attend school. Sometimes, learning disabilities such as dyslexia and dyscalculia are comorbid with ADHD, making it even harder to learn.
