Besides being totally off topic, you can't do that direct comparison. First 
off, our default scenery lacks a lot of detail in the urban area boundaries in 
that area thus marking a far larger area as being urban -> a far larger area 
on which to generate buildings;  second,  the generated random buildings are a 
mixed set of residential and comercial/office buildings, so the math is a bit 
off there.

Actualy the Geater LA + Inland Empire area should use more somewhat small 
buildings, as the overwhelming majority of the residential buildings in that 
area are individual houses, all the way  E to San Bernardino.
