In 2021, research showed that for every 100 white children diagnosed with ADHD, there are 83 Black and 77 Hispanic children, and just 48 Asian children, with the diagnosis.
The prevalence estimates of ADHD in Mainland China, Hong Kong, and Taiwan were 6.5%, 6.4%, and 4.2%, respectively, with a pooled estimate of 6.3%.
The highest rates emerged from Africa (8.5%) and South America (11.8%). Corroboration comes from a dimensional ADHD scale used in 21 countries. Japanese and Finnish children scored lowest, Jamaican and Thai children scored highest, and American children scored about average (7).
Researchers examined data on more than 17,000 children in the United States in another study, published in Pediatrics. They found that compared with white children, Black children were 36 percent less likely and Latino children were 56 percent less likely to be diagnosed with ADHD.
The prevalence of adult ADHD is estimated as 1.65% in Japan [3] and 1.2 to 3.2% [2, 4] worldwide.

Conclusions: ADHD may be a common disorder among Chinese children, the symptoms of which may increase the likelihood of parent depression. There is a need for greater detection of ADHD in schools and an acknowledgement of the challenges the disorder creates for academic success and family wellbeing.
Pooled prevalence rate of ADHD was 15.9% (95%CI 11.6% - 20.7%) among Black children and adolescents, 16.6% (95%CI 11.6% - 22.2%) among Whites, 10.1% (95%CI 6.9% - 13.8%) among Latinos and 12.4% (95%CI 1.4% - 31.8%) among Asians.
Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Around 1 in every 20 Australians has ADHD. While ADHD is more common in boys — it's under diagnosed in girls and adults. More than 3 in 4 children diagnosed with ADHD still have symptoms as an adult.
ADHD is the most prevalent mental disorder affecting children in Australia – it affects approximately 281,200 Australian children and adolescents (aged 0-19) In Australia ADHD is currently under-diagnosed, particularly in girls and in the adult population.
Rather, the rise seems to be due to an increase in access to healthcare; a decrease in stigmatization about receiving mental health care; and greater awareness of the symptoms of ADHD among clinicians, guardians, educators, and patients. In the past, ADHD was only diagnosed in children who were hyperactive.
It is defined by the symptoms of inattention and/or hyperactivity/impulsivity. The prevalence of ADHD is reported to be 3–7% in children in USA,1 and approximately 7.7% in Japan (using parents' rating).
The prevalence of ADHD among the adults have been studied in a small scale (6-8), which did not provide information on the prevalence in children. The prevalence of ADHD in children was reported with a wide range such as 5.9% and 9.0% in Korea, even though they were confined to Seoul (9,10).
Studies investigating the characteristics of Korean ADHD patients have reported similar patterns to international studies. Despite methodological differences, some studies have reported the prevalence of ADHD in the Korean population to be 5.9% to 8.5% [15-17].
You can inherit genes that boost risk for ADHD from your mother, from your father or from both parents. In a recent Norwegian study, inherited risk was somewhat higher when a child's mother had ADHD compared to their father, but researchers weren't certain why that would be.
These may include hyperfocus, resilience, creativity, conversational skills, spontaneity, and abundant energy. Many people view these benefits as “superpowers” because those with ADHD can hone them to their advantage. People with ADHD have a unique perspective that others may find interesting and valuable.
The CDC study, reported in March of this year, found overall, 14% of children 3-17 have ever been diagnosed with either ADHD or learning disability, including 17% of Black children, 15% of white children and 12% of Hispanic children. (See chart.)
ADHD prevalence among Japanese adults was estimated to be around 1.65% [8], which is lower than the estimated 2.5% prevalence of ADHD in adults from a meta-analysis [9].
For adults with AD/HD, the prevalence is around 2.5%. The prevalence of AD/HD in Hong Kong is similar to that in other countries.
Although the prevalence of ADHD in Singapore has been estimated to be less than 5%,* ADHD is the fourth-highest contributor to disease burden (as measured in disability-adjusted life years) in children aged 14 and below.
The prevalence of ADHD among Arab populations is variable according to published studies, ranging from 6-16 percent. That is more or less equivalent to the occurrence in the United States, where the prevalence is reported from 5-10 percent.
ADHD is estimated to affect around 5% of children and 2.5% of adults worldwide, according to the World Health Organization (WHO). However, these estimates can vary depending on the criteria used for diagnosis and the population studied.
