The preliminary results of the 2010 U.S. Census are in, and so far they depict a California quite different from the one that the state's localities have been planning for the past few decades. It is no longer a young, family-oriented state that lives in detached homes but rather an aging, childless state that is turning back towards the center cities. And, though California's population - estimated at 37.2 million - is bigger than ever, its growth rate is a shadow of its former self.
