It seems the whole universe is designed based on the principle of economy of scale, from metabolic rates, to vascular systems, cancer growth, aging, mortality, etc. Those are log (x) correlated (<1.00) - metabolic rates, for instance, stand at 0.75. When it comes to cities, economies of scale still apply. Examples are less paved roads and gas stations per capita. Those are super-linear correlated (e(x) or >1.00) at 1.15 on average.
