The neuron difference between the highest and lowest number you posted, is ~0.1%, placing it in the realm of statistical irrelevancy. Neurons are formed by activity, just like muscles. Every time you have a unique experience, or perform the same task, in a different way, you form new neural pathways and stimulate neuron formation. The greatest impact on cognitive neuron formation, in a population, is native language - the more complex a language and the more it engages other parts of the brain, the more pathways are mapped by its use. Also, the term 'average' is completely inadequate and skews perception. In population statistics, we use ordinals, not averages, because they reflect what is 'normal', where the largest sample falls, not the difference between the lowest and highest samples.
There is no such thing as an 'IQ test'. There are batteries of tests that measure different attributes and the relationship of those individual scores to each other, is how IQ is derived. For example, someone who is a math savant, with no mechanical reasoning or spatial relationship skills, will score lower than someone who scores the average, across the board. We see this with Autism Spectrum Disorders. Therefore, methodology is paramount to validating population groups' 'IQ' scores. Sub Saharan 'average IQ' might be 70, but on what scale? Who performed the testing and was the compiled battery matched to the population? Would an Asian accountant fare very well, where they have to determine if something is tasty, or poison, by pure rationale? Could they properly gauge the risks? Would they know the difference between the wind and a predator? These skills are predicated on high level reasoning and not simply by experience. You cannot give population groups in fundamentally different environments the same test and directly compare results - someone with no use for calculus, is not 'dumber' than someone who knows it because they have to. Furthermore, 'IQ' is a nominal measure. A score is only relevant, within its nominal group and the scale is skewed to place 100 as the 75th percentile - 75% of a group has an IQ of 100, be the group a gaggle of Anglo-Saxon astrophysicists, or a room full of rainbow mix toddlers. That means that 100 today, is not the same as 100 a generation ago, or a generation from now.
This is a very complex subject with a lot of internal controversy. It doesn't need the BS that comes with being a virtue signal or political cudgel, as well.
