Here is the average IQ by country for the year 2022. This result is based on 1,565,983 results from around the world who took the test in 2022. The countries in gray on the map below have been ignored because there wasn't enough data to include them.
It is interesting to note that only 33 of the 125 countries in this study have an average IQ score above 99. This is mainly due to China, which with its average score of 106.59 and its very large population, balances the overall average score at 100.
The average IQ seems to be generally higher in East Asia. Close to average in Europe, Western Asia, Oceania, North America and North Africa. And below average in Central and Southern Africa, and Latin America.
