[Marvel] Just what is the Earth’s population?

I understand that the population of humans is about the same as real-life Earth, and that there are about 200,000 mutants on Krakoa.

But there’s a whole Sub-Earth that is rarely mentioned. Lava Men, Atlantians, Lemurians, Deviants, Inhumans (though I guess they live on the moon), the microverse, etc etc.

How busy is this planet?

It seems that the overwhelming majority of the population, even with all the additional species and subspecies, is still good old fashioned *Homo Sapiens.*  Even the largest non-human terrestrial civilizations don't look they'd be in more then the millions, and most much less.

As such, I'd say population is roughly the same as our world even taking our non-human neighbours into account- a few countries worth higher at most. 8 billion is simply too big a number for a few underground cities or underwater kingdoms to have much of an effect.
