Not to get too deep into the weeds, but you might want to be leery of some of those numbers: a hot topic in the Greyhawk meganerd community is if those are actual population figures, or military manpower figures: so there may not be 5 million people in the Great Kingdom, it might be that there are 5 million eligible for military service. Amd there is reason to think that based on the text, IIRC.
Oh I totally agree. The numbers are very likely not plausible.
But that does mean there are huge numbers of unaccounted for beings in the setting.
Beings like Dragonborn…
