The ADHD statistics in the United States are staggering. ADHD, or Attention Deficit Hyperactivity Disorder, is a mental health disorder. It affects millions of Americans and costs billions of dollars each year.
The prevalence of ADHD has been steadily increasing over the past decade and there doesn’t seem to be an end in sight. It is important for those who suffer from ADHD as well as those who don’t to understand what it entails.
Get to know more about this condition so that you can better help them. They need information, not stigma or shame. In this blog post, we will explore some facts about ADHD that you may not have known before.
What percent of the population has ADHD in the United States?
According to epidemiological research, around 5% of adults have attention deficit hyperactivity disorder. ADHD occurs in males and females. In most cases, ADHD will continue throughout a person’s lifetime.
According to statistics, ADHD is the most common neurobehavioral disorder diagnosed in children. There is no cure, and most children do not outgrow it. Approximately two-thirds or more of children with ADHD will need treatment into adulthood.
ADHD Prevalence in Children
6.1 million children (9.4 percent) have an ADHD diagnosis. These children are between the ages of 2-17. The diagnosis of ADHD was long associated with boys than girls, but this is no longer the case. Due to the fact that males are more hyperactive and are subsequently diagnosed, girls are often overlooked.
- 388,000 (2.4 percent) of children ages 2-5 years old.
- 2.4 million (9.6 percent) of children ages 6-11 years old.
- 3.3 million (13.6 percent) of children ages 12-17 years old.
ADHD is the most common neurodevelopmental disorder in children. ADHD is a chronic condition that affects many areas of development and functioning.
ADHD Prevalence in Adults
ADHD is a mental health disorder that affects an estimated 2.8 percent of American adults. The United States has the highest rate of ADHD in adults compared to other countries worldwide.
ADHD is not just a problem for children, ADHD can also continue into adulthood, and is the most common mental disorder in adults.
A 2019 study estimated that the prevalence of adult ADHD was 0.96 percent. This percentage had doubled from 0.43 percent ten years before. ADHD is extremely underdiagnosed in adults.
ADHD Treatment in Children
When children have ADHD, there are different ways they can get help. Parents can also do things to help their children without medicine. Medication is used the most in the treatment of ADHD. Around 75 percent of children receive some type of ADHD treatment. In children:
- 31.7 percent receive medication and behavior treatment.
- 30.3 percent take only ADHD medication.
- 14.9 percent will receive only behavioral treatment.
62 percent of children currently take an ADHD medication. While 46.7 percent of children receive behavioral treatment for their ADHD.
ADHD medication in children has both positive and negative effects. ADHD medication can help students in school. It also has the potential to affect their growth if they are taking these medications for an extended period of time.
Children also receive support from their schools when they have ADHD. ADHD can cause children to have trouble paying attention in school, which is the reason ADHD affects students grades. This lack of concentration causes ADHD sufferers to have bad grades. ADHD can make it more difficult to find friends, which is why most children with ADHD are bullied at school.
- 80 percent of children who have ADHD receive school-based support.
- 40 percent of children have been given social-skills training.
- 31 percent of children have participated in parent training.
- 20 percent of children have received cognitive behavioral therapy (CBT).
ADHD is increasingly being diagnosed in teens who suffer from other mental health disorders. These include depression, anxiety and obsessive-compulsive disorder.
ADHD can also be mistaken for bipolar disorder. It is very important for people who have ADHD to know the difference between the two. Then they can know how to best treat this condition without falling into an incorrect diagnosis.
For two-thirds of children who have ADHD, they have at least one other condition.
- 51.5 percent of children who have ADHD will also have behavioral/conduct problems.
- 32.7 percent of children with ADHD also have anxiety problems.
- 16.8 percent of children with ADHD will have depression.
- 13.7 percent of children with ADHD have also been diagnosed with autism spectrum disorder (ASD).
- 1.2 percent of children with ADHD have been diagnosed with Tourette syndrome.
- Around 45 percent of children with ADHD also have a learning disorder.
- Loss of Control Eating (LOC-ES), a type of eating disorder, affects 12 times more children with ADHD.
Children with ADHD
The majority of children with an ADHD diagnosis have mild to moderate symptoms:
- 43.7 percent have moderate ADHD symptoms.
- 41.8 percent have mild ADHD symptoms.
- 14.5 percent have severe ADHD symptoms.
Severe ADHD is usually given an earlier diagnosis, at five years old.
ADHD is likely hereditary. 41 to 51 percent of families with a minimum of one child diagnosed with ADHD will have a parent with the condition.
One in five students who are diagnosed with ADHD does not receive the proper school-based services that they need to succeed. ADHD can cause students to struggle, which is why this statistic is important. Parents should contact their child’s school and talk to them about an EOP or 504 plan for their child.
Parents should also contact their child’s teachers to ask for ADHD accommodations. Students with ADHD need their parents to help them do well in school and get the support they need from teachers.
The number of children who have ADHD has been tracked via parent-reported ADHD diagnosis. There is little evidence about how reliable these reports are as a sign of a medical diagnosis.
When they used numbers from parent reports, the estimate for ADHD was about the same as when they used numbers from health care records. This means that using what parents report may be a valid way to track how many children have ADHD in the community.
Teens with ADHD
Teens with ADHD are at increased risk for substance abuse, anxiety disorders, mood disorder. They may also have problems in school such as truancy or dropping out due to the fact they can’t keep up academically.
About two-thirds of teens who suffer from ADHD also have problems with anxiety. This is because ADHD can make teens feel stressed by their everyday life. This can lead to other problems like anger, depression, or even learning disabilities.
Teenagers with ADHD tend to be in more traffic accidents, be issued moving violations and engage in risky driving behaviors. ADHD also causes teens to have an increased risk of self-harm, suicide attempts and suicidal ideation.
27 percent of teens with ADHD will also have substance abuse disorder. Teens with ADHD tend to also clash with their parents more. Teenage girls with ADHD will tend to struggle with social acceptance and have poor self-esteem. Teen boys with ADHD have more problems in school. This is with attendance, GPA, or focusing on homework.
- Teen boys with ADHD miss school three to ten percent of the year.
- Teen boys are more likely to drop out of high school between 2.7 and 8.1 percent of the time.
- Teen boys with ADHD fail 7.5 percent of their classes.
- Teen boys with ADHD have lower GPAs. Usually five to nine points lower than teen boys without ADHD.
Adults with ADHD
According to statistics on ADHD adults account for roughly 5 percent of diagnosis. ADHD is usually diagnosed in children, however ADHD does not end when a child becomes an adult. ADHD will continue into adulthood and the symptoms of ADHD must still be present.
ADHD can make life difficult for adults. It can be hard to hold a job, maintain healthy relationships and keep up with responsibilities of everyday life. This can include things such as paying bills on time or cooking dinner. ADHD can cause adults to fall into debt, lose their jobs and even have their car repossessed. This is due to the ADHD brain’s inability to focus long enough on the task at hand.
Women are more likely to find an ADHD diagnosis as an adult. Girls tend to have inattentive ADHD and are not diagnosed as children. This is because their behavior is not as disruptive as children who have hyperactive ADHD.
Women who have ADHD are more likely to suffer from low self-esteem and have anxiety. ADHD medication is used less often by females than males.
ADHD Statistics: Demographics, Race & Ethnicity
ADHD affects many children and adults worldwide. It’s important to understand that there are certain demographics in America and around the world who suffer from ADHD more than others.
In the years 2016-2018, about 13.8% of children aged 3-17 had ever been diagnosed and had ADHD or a learning disability. Black children (16.9%) were more likely to be diagnosed than white (14.7%), Hispanic (11.9%), and American Indian/Alaska Native children (12%).
This means that non-Hispanic black children aged 3–10 years, were more likely to be diagnosed with ADHD or a learning disability. This is compared with non-Hispanic white or Hispanic children.
Kids aged 3-10 are less likely to have ADHD or a learning disability than kids ages 11-17. This is true for every race and ethnicity.
For children of all racial and ethnic groups, the federal poverty level had an impact on the diagnosis of ADHD or a learning disability. Only non-Hispanic white children were diagnosed differently by parental education.
Rates of ADHD among adults of all races and ethnicities are increasing, but gaps remain.
- White individuals: 0.67 in 2007 increasing to 1.42 percent in 2016.
- Asian individuals: 0.11 in 2007 increasing to 0.35 percent in 2016.
- Native Hawaiian/Pacific Islander individuals: 0.11 in 2007 increasing to 0.39 percent in 2016.
- Black individuals: 0.22 in 2007 increasing to 0.69 percent in 2016.
- Hispanic individuals: 0.25 in 2007 increasing to 0.65 percent in 2016.
- American Indian and Alaskan Native individuals: 0.56 in 2007 increasing to 1.14 percent in 2016.
How common is ADHD in 2021 in the United States?
In the past, attention deficit hyperactivity disorder was not taken as seriously as it is now. In the United States, many people now get help for their mental health problems. This means that ADHD is found and properly diagnosed more frequently.
ADHD is the most common mental health problem of children and adolescents in the United States. ADHD is estimated to affect over 6 million children.
Who is most affected by ADHD in the United States?
Male children are more frequently diagnosed with ADHD. This is because males tend to have more hyperactive symptoms that cause disruption. The proportion of males with ADHD is 12.9 percent, whereas the proportion of females with ADHD is 5.6 percent.
Children ages 12-17 years old are most likely to be diagnosed with ADHD. When children enter secondary school, they often start to show symptoms of ADHD.

- Asian (15%)
- White individuals (14%)
ADHD affects many people, but some groups are affected more. For example, those who live below the poverty line and girls versus boys. It also affects adults ages 26-34.
A study of 19 research papers including over 150,000 US Black children ages 12 to 18 years old showed an ADHD prevalence rate of 14%. The authors stated that black people are more likely to have ADHD than the general population of the US. More attention needs to be paid to the ADHD diagnoses of Black people. There are different social backgrounds that need to be taken into account.

We can use the US Census Bureau to figure out how many children are in this age group in the world. There were 1,795,734,009 people aged 5-19 worldwide in 2013. This means that 7.2 percent of these people have ADHD which is 129 million children worldwide who have ADHD.
