Ryan Briggs in Next American City reports that families are staying put in Philly and Baltimore downtowns:

While urban revitalization is often stereotyped as dominated by young
professionals and retirees, Census data found that the Greater Center
City area had an even balance of all age groups. Data from the year
2000 indicated an average household size of 1.7 people in the eight
ZIP codes. That figure had ticked up to 1.75 by 2010 — a trend CCD
– attributed to couples opting to raise children in the city.

And from Philly.com comes news that Philadelphia is listed in Lonely Planet’s Top 10 US Destinations for 2013:

Forget the cheesesteaks and tri-corner hat, Philadelphia is becoming
known as an art capital. In addition to the world renowned
Philadelphia Museum of Art, the formerly remote Barnes Foundation , a
once private collection of Matisse, Renoir and Cézanne, has a new
central location. And it’s not just the big museums – Philly’s gallery
scene is exploding with new venues like the Icebox garnering
international attention and turning the Northern Liberties and
Fishtown neighborhoods into the new hot arts hub. First Fridays , the
monthly gallery open house, long a tradition in Old City, has expanded
to the refurbished Loft District, where the party goes on in a host of
new bars, clubs and live music venues.
