- Data are estimates from the Institute for Health Metrics and Evaluation and are based upon the best available data. As all estimates involve some degree of possible inaccuracy, the highest and lowest imagined values are shown as well.
- Data displayed are the values per 100,000 individuals in the given country’s population.
Worldwide, attention-deficit hyperactivity disorder (ADHD) affects about 2.2% of people overall by 2017. This rate fluctuates between .1-8.1%. In Asia, Europe, North and South America, and the Middle East, the range is from .6-7.3%.
ADHD In Children and Adolescents
Not all countries have published data with ADHD for children younger than six years old. Some places do have records concerning this, however. The percentages equal 1.9% for Norway, 1.8% for Germany and 5.4% for Spain.
The World Health Organization (WHO), also surveyed 20 lower-middle to upper income countries. This revealed the U.S. as having the highest ADHD rate at 8.1% in children and adolescents. The three lowest are Iraq at .1%, Poland at .3% and Romania at .4%. Data from this study comes from as late as 2017.

European ADHD Gender Study
Another study, called the European ADORE study, took place over a period of 24 months. It includes research pulled from 10 EU countries ages 6-18 years. Out of 1478 children studied, boys with ADHD totaled 1222, which make up 84.3% of this group, and girls 231, which equals 15.7%.
Gender ratios indicated by countries included in the ADORE study measured 1:3 in females and 1:16 in males. Data reveals more diagnoses of ADHD in adult males than adult females in many locations. However, the ratio of males to females with ADHD has decreased with age.
