IQ is normalised by age (apparently, it seems hard to find simple info on this) which suggests if you score 100 you are average, for your age.
In a society where nearly everyone goes to school, that seems like a confounding factor. Every year older will mean, for most people up to age 16 or so, another year of education.
Feels like you could pull some interesting info out of that, but not sure how.
