Simon would have loved before he had so many more important things to think about. To the Journal's credit (and I can't remember if I've ever said that before) the subtitle is: "Ithaca one of few to grow" and they include a table of data from Tompkins County and the towns and villages in the county.
A look at the data shows that NYC grew by .3% since 2000 while Tompkins County grew by 4.7%. The increase is distributed throughout the county ranging from 11.1% growth in the Town of Ithaca to 1.1% and 1.2% respectively in the towns of Groton and Newfield.
It's interesting to me that the Village of Cayuga Heights (in the Town of Ithaca) grew by 12.3% while the populations of all other villages in the county remained nearly unchanged. That's a trend we hope to change as more towns adopt land use plans to encourage growth in villages and hamlets.
