Richard Florida argues in his new book, The Flight of the Creative Class, that the information workers who increasingly dominate the world's economies often choose their regions and neighborhoods for aesthetic and cultural reasons.
Louis Uchitelle in the New York Times chronicles a bit of this demographic movement to a suburb of NY City:
[The] Stovers and the Hirschfelds, like nearly all of the owners before them, came to Hastings from apartments in New York City, choosing the town in part because it offered a demographic mix greater than many other suburbs, as well as neighbors who were often artists, writers and academics.Joel Kotkin, in The City: A Global History (which I read about over the weekend) notes the movement and decentralization of knowledge workers, too, though he's critical of Florida's ideas in his final chapters, deriding the notion that making your city "cool" or "hip" will attract these workers.
And yet Kotkin himself writes lovingly of Los Angeles' and New York's urban amenities-- the places where he himself chooses to live and work. To me, Florida's data seemed more detailed, focused, and up-to-date than Kotkin's.
