Population isn't very relevant when we're speaking specifically of things that relate to land area like topological maps.

But we aren't speaking of land area, we're speaking of buildings, which relate to population. I'd wager that LA County has more buildings than Finland.

But we are talking about building footprints which DO directly correlate to population, not overall area of an entity. So it's the most relevant factor.

Not really

Arizona and Croatia have the same population, but look at the aerial maps...
