The US is not very dense

Many countries make use of space by cramming people into buildings, subways, public transportation, small apartments, skyscrapers, trains, tiny automobiles, etc.  Yet the US continues to take up more space per person rather than more persons per space.  SUVs and personal vehicles over buses and subways. Apartment buildings, homes, offices and condos that are built short and take more space per unit.  Roads and utilities that stretch for miles.  Huge space between buildings dedicated to parking lots and lawns, or just unused land left to be paved over in the future.  If it were Asia, everything would be like New York.

     Acutally the birth rate of america is slowing down, and the average age at which people have children is raising.  the problem is this is an average over the last ten years.  the poor are actually having more children sooner, where as middle class is haveing fewer children latter in their life.  i wonder which class is more intelligent.
