As you can see, it’s centered on 100 — that’s by design — and there are far more people in the middle range than at the high and low extremes.

It should be pointed out that the current system of IQ scoring is based on a normal distribution, with 15, 16, or 24 points (depending on the test) corresponding to one standard deviation — those are the white vertical lines above. That’s all by design and reflects the fact that mental age, which was originally used to calculate IQ scores, is affected by multiple genes and environmental factors, so tends to have this kind of statistical distribution.
The distribution is not perfectly bell-shaped though in the real world. For example, it seems that men are more likely than women to get scores at either extreme, high or low.

Average IQs in various countries
From V. Buj, Person. & Individ. Diff., Vol. 2, pp. 168 to 169, 1981
Subjects >16 yrs. old tested on the Cattell Culture Fair Test 3 (16 SD), standardized in the USA (IQ=100).
The following are some children’s relatively modern IQ scores relative to American norms (IQ=100), on a 15 SD scale and based on both verbal and performance type data, unless otherwise stated. The Asian data are the highest scores found in the data sources. That is, sometimes studies find lower Asian scores. On average, children from Asian countries get about a 107 IQ relative to American norms.

In Nagoya Japan, the score was 110.24. It was adjusted up by 3.34 points because testing was done on the Canadian Cognitive Abilities Test (see note 1). Source: Takeuchi and Scott (1992) as cited by R. Lynn (1997), Geographical variation in intelligence. In Helmuth Nyborg (Ed.) The Scientific Study of Human Nature. It seems that the Japanese gains have started to level off.
