what is the average iq

The average intelligence quotient (IQ) is between 85 and 115. However, this number can vary between countries, states, and even geographical regions. An IQ score is defined with a median and mean of 100, and 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” . 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. According to 2019’s The Intelligence of the Nations report, the average IQ in the United States is 97.43. However, the average IQ of countries around the world can vary, with a 2010 study finding that the average IQ across the globe was 89.
