Area preserving projections of the surface of a sphere onto a plane will also tend to be population preserving projections.
It is not surprising at the Peters projection better represents population density.

Incidentally, the mathematics of the Peter's projection is the same mathematics that makes it possible to ride a tricycle with square wheels on a bumpy road.
The Texas A&M Physics Department's square -wheeled trike, built by the machine shop. The trike rides on a road of repeated pieces of an inverted catenary.

I'd love to see a world map inverted, or at least with the southern hemisphere accentuated and highlighted, so we could see the regions not usually depicted. I mean, the early navigators managed to get around both South America and Africa, but world maps don't even give Antarctica hardly a blip.
