The average intelligence quotient (IQ) is between 85 and 115. However, this number can vary between countries, states, and even geographical regions. IQ is a standardized method used to assess a person’s mental aptitude compared to a group of their peers. In general, an IQ score is defined with a median and mean of 100. Scores above 130 are labeled as above average or “very superior,” while scores under 70 would be considered below average or labeled as “borderline impaired” . Most people have an average IQ between 85 and 115. Overall, about 98% of people have a score below 130, and only 2% of the population score above that and are considered above average. The standard deviation of IQ scores is set at 15, which means that around 68% of people will have an IQ score between 85 and 115.
The average IQ of countries around the world can vary, with the average IQ in the United States being 97.43. The average IQ for each age group may also vary, with the average score for 16-17 year-olds being 108, the average score for adults between 18 and 19 years of age being 105, and the average score for people between 20 and 24 years of age being 99.
