Does An Aging Population Spell The End Of Suburbia?

Matt Yglesias highlights one trend, aging,  to posit another trend, a return to urbanism. From what he says, I doubt if he has ever been to Frisco, McKinney, or Southlake. He certainly never has had to drive kids to the only great soccer fields around, which are in Plano.  However, I did note two interesting comments. One makes the point that some suburbs are becoming self-contained urban centers in themselves, and if the urban trend is true, it will take place in pods like those as well as in core cities. The other notes that aging suburbs are already being infilled by the poor, which is a trend we are seeing here.
