Your intelligence quotient – or IQ as it is frequently called – is a measure of human intelligence. People that want to have their IQ measured take standardized tests and receive a score which ranks their level of intelligence. A high IQ indicates that a person is intelligent. A low IQ indicates 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. When looking at the average IQ scores of each country, 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 shown shades each country depending on the how high the average IQ score is. A higher IQ score is indicated by a darker shade of violet.
There is a range of average IQ scores across the globe. All of the 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 The 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 around the world, 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 the highest IQ scores in 2019 of 108. South Korea has the second-highest IQ score of 106, followed by Japan and China with an average of 105.
However, it’s important to remember that IQ isn’t the only measure of intelligence. Nations can also be ranked based on factors such as 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.
