No, it is related to the world wars. And the bottom part of the list is orders of magnitude lower than the first (the last colour is actually 0 with a slight difference from grey and the group above it has 1 while France is several hundred thousand). I tried to do it as one colour shaded to accurately represent the proportion, but that left most of the map basically white.
As such, you are probably better off ignoring everything below Australia, South Africa, and Libya). As an addition, a large majority of China's are in Hong Kong, I don't have the actual split, though.
