What are the mathmatical facial bone ratios for each race(eugenics)

[AsceningC]

I have been wondering recently about eugenics and mathmatics and the correlations between different races. For example on average for asians and for northern europeans how much do their facial ratios differ in the mid face or how abtuse the gonial angle is for each race.

Does anyone have any answers with ratios to see how much the bones differ in each race?
