Average IQ by Country (World Map and Table)

What is the Average IQ?

IQ (Intelligence Quotient) tests are designed to evaluate cognitive abilities and estimate an individual's intelligence level. While different IQ tests may vary in format and methodology, the average IQ score is standardized at 100.

For about two-thirds of people, IQ scores typically fall between 85 and 115, which represents the normal IQ range.

Average IQ and Normal Distribution

The measurement of intelligence remains a debated topic in psychology and education. Researchers and psychologists have studied IQ differences across populations for decades. Some significant national IQ datasets have been compiled by researchers such as Richard Lynn (National IQs calculated and validated for 108 nations), though these studies remain controversial and widely discussed.

In this model:

• 100 represents the average IQ score
• A standard deviation of 15 points is considered typical
• 68% of people score between 85 and 115

This statistical model allows researchers to compare results across different populations and countries.
