Each year, the University City District compiles, in a glossy report, the vital signs for the eastern half of West Philly. For a while now, the trend lines have been strong. But this year, the numbers are truly staggering.

There’s more.

Put it all together, and it’s clear that Philadelphia now has two downtowns. That’s not an exaggeration. University City has more salaried jobs than does downtown St. Louis.

But University City is a very atypical downtown. It’s dominated by a handful of mega-institutions (Penn, Drexel and CHOP, but also the IRS and the Veterans Administration) that together account for more than 50,000 of those 75,000 jobs.

Except for the IRS, those institutions aren’t new to West Philly. So what explains the boom? For one, the institutions themselves are booming, particularly CHOP and Penn Medicine. That in turn has generated a boom of private sector interest in University City. Private developers and entrepreneurs are, increasingly, seeing opportunity in a section of the city that not long ago was seen as an institutional zone. That’s a relatively new phenomenon (and a welcome one for City Hall and the School District, as non-profits like Penn don’t pay property taxes).

“I think it’s a quintessential virtuous cycle. Growth begets more growth. Private developers are seeing more and more opportunities,” said Matt Bergheiser, Executive Director of the University City District.

The obvious comparison is to Cambridge, where the presence of Harvard and (especially) MIT — which has long emphasized tech transfer and business incubation — lured firm after firm to set up shop in the town.

That hasn’t happened yet on nearly the same scale in University City. But that’s the goal, and there’s a lot of concerted institutional effort underway to make it happen; from the Science Center, to Pennovation Works (on the other side of the Schuylkill) to Drexel’s planned Innovation Neighborhood.

If talk of business incubation makes your eyes roll in a I’ve-heard-this-before-way, I get it. But looking at the University City skyline this past year, it’s hard to be bearish.

Where does all this leave the rest of West Philadelphia?

“Penntrification,” as it is still called, is a nearly 70-year-old phenomenon with a really wretched history, particularly in earlier years. The institutions operate much more carefully now, and are far more invested in the neighborhoods that surround them — but tensions remain.

For all the big money being spent within University City, West Philadelphia as a whole remains more impoverished than the city overall. Unemployment in West Philly is higher than in the rest of the city as well.

That gap — between the boom in University City, and poverty rates and job prospects in most of West Philadelphia — is deeply worrisome. UCD leaders say they understand this, and they’ve got what looks like a successful training program that matches West Philly residents with actual job openings in University City’s anchor institutions. We’ll take a closer look at that program, and the broader disparity challenges in West Philly, soon.
