I’ve been monitoring this post from Devo on X:

Hmm… yes. This is a good question.

Kneejerk response, I’d say that Philly’s Pennsylvania suburbs transform into the exurbs at the end of the Regional Rail lines. So anything north and west of Doylestown, Chalfont, and Lansdale, for starters. Looking at Lower Bucks, I think you’d draw the line right around the Richboro/Newtown area, like Almshouse Road or maybe Swamp Road. Then, on the western side, you’d say anything west of Thorndale, so Coatesville and Marsh Creek using 322 and West Chester as a reference point, more or less. If you go a little further south you can run the border going diagonally from Garnet Valley:

Is that reasonable? I think you have to bend the line around that Exton/Downingtown corridor because people commute into the city from there. But you go further north and you get into that portion of Chester County between Route 100 and Phoenixville and that feels like exurbs to me. Everything is a lot more spread out and the population isn’t nearly as dense.

The one thing that screws up the Regional Rail line of thinking is middle Montco. There’s no train line going up past Norristown, but there are parts of the 422 corridor like Oaks and Audubon that are definitely suburban. Phoenixville is right over the county line, but Phoenixville is a Philadelphia suburb. I don’t think you truly flip over to bumble-ish territory until you get up beyond Limerick and Schwenksville and drive Route 73 or Swamp Pike and touch the edges of the Perk Valley, Boyertown, and Upper Perk school districts. Then you’re close to the Berks County line and can get to Reading faster than Philly.

If I had to draw an arbitrary map, it would look like this for Montco:

What say you? There are some outlier towns on here. I think Trappe and Royersford are hard to place. Souderton and Harleysville I don’t think are Philly suburbs. And even though the train runs up to Doylestown, that area around Warrington and Jamison is pretty spread out. Maybe we can crowdsource and make some rulings here.

Good post from Devo.

EDIT – I want to make a map for Bucks County. This one was tougher, but I think I’d do it like this, though that Sesame Place area kind of messed me up. I think the line would go along Route 1 there because I just don’t think you can say Yardley is a Philly suburb. But I could be wrong:
