Your intelligence quotient – or IQ, as it is frequently called – is a measure of human intelligence. People who want to have their IQ measured take standardized tests and receive a score that ranks their intelligence level. A high IQ indicates that a person is intelligent. A low IQ suggests that a person is of lower intelligence.

An IQ score refers to a value that measures intelligence levels. Shorthand for intelligence quotient, IQ scores typically reflect the quality of education in certain parts of the world, as well as the accessibility and resources available to people in those geographic regions. Many people may also use it to determine the smartest countries in the world.

When looking at each country's average IQ scores, you will notice that areas of the world with lower IQ scores are less developed and poorer than countries with higher IQ scores. The IQ map shades each country depending on how high the average IQ score is. A darker shade of violet indicates a higher IQ score.

There is a range of average IQ scores across the globe. All countries have been divided into ranked categories based on their average IQ scores. The lowest IQ on average in the world is 59, while the highest is 108.

The country with the lowest IQ score, on average, is the Equatorial Guinea in Africa. Those who reside in Equatorial Guinea have an average IQ of 59, which is 49 points lower than the average IQ of Singapore and Hong Kong.

IQ testing takes place worldwide, and this data has been compiled to rank the most intelligent nations based solely on IQ. According to the most recent data, Singapore and Hong Kong have the highest IQ scores in 2019 of 108. South Korea has the second-highest IQ score of 106, followed by Japan and China with 105.

However, it's important to remember that IQ isn't the only measure of intelligence. Nations can also be ranked based on school test rankings or the number of Nobel Prizes won throughout the years. For example, Singapore has the highest IQ but is not considered the smartest nation in the world. That honor goes to Japan, which is ranked more highly in school test rankings and the number of past Nobel Prizes awarded.

Here are the 10 countries with the highest IQ:

  1. Hong Kong (108)
  2. Singapore (108)
  3. South Korea (106)
  4. China (105)
  5. Japan (105)
  6. Taiwan (104)
  7. Italy (102)
  8. Switzerland (101)
  9. Mongolia (101)
  10. Iceland (101)
