Worldwide Distribution of IQs

National average IQs can be used to calculate a global average IQ. However, due to differences in population sizes, they are not normally distributed, and it is impossible to calculate the IQ distribution from this average. To estimate the number of people in the world with an IQ above a given value, it is necessary to go through the intermediate calculation of a theoretical average IQ following a Normal Distribution. Using the average IQ and population data of 204 countries, this article provides the formula for calculating this intermediate and gives figures for IQs from 55 to 160 in steps of 5 IQ points. It shows that there are many more high IQs than the world average would suggest. For example, there are about as many people in the world with an IQ above 157 as there would be if the world average were 100 and IQ were distributed according to a normal distribution.
