Old is as old was
There is a longer term story here of course. From, frighteningly, 13 years ago is this oped: We're getting younger every year. I take responsibility for the title, though I think it would have been better phrased that everyone is getting older faster than we are.
So the story continues today. Governing is just out with a story and data on aging by state.New Census Estimates Show Areas Growing Oldest the Fastest. In their table you will see that Pennsylvania's elderly population increase is one of the slowest growth rates in the nation. Between 2010-2012, our elderly population increase by 0.5%. States such as Colorado, Utah, Texas, and North Dakota all had increase over 3%. It is going to be an ongoing trend well into the future.
The news today is just based on some new county level data put out by the census. There is no update for municipal level demographics. Nonetheless, the story is really a corollary to the trends that have been going on in the city for going on two decades now, even though I know many think this is a new story.
