I would eliminate the triple split of Butler
Boundary in Beaver is the Ohio River. Obviously you could put some piece of Warren or Venango in instead, but I don't see the point.Your claim is that your proposal is "fair". One characteristic of fairness is that you apply rules consistently and uniformly. It would appear that one of your rules is to not split counties, except where it is necessary for population balance.
Beaver County is not being split because the Ohio River goes down the middle of it (if it were a significant barrier, the county itself would be split). Erie County is way short of a district and you would have to go way east in thinly populated northwestern Pennsylvania. So instead you come south into the Beaver Valley, which becomes a major population center in itself. If you needed some more population, you wouldn't have worried about including the whole of Beaver County. If you come across the Ohio River on the numerous bridges, you can eliminate the 3-way split of Butler County. Since the areas in Butler County are along the interstate, they are quite likely to be Pittsburgh suburbs and not associate with Erie or the Beaver Valley at all.
Easily possible. Just gonna look damn ugly.[/quote]
Not really. You use the northern boundary of Westmoreland further east, and it doesn't look ugly. It looks like a stream boundary. You could include all of Armstrong in the Northern district, and extend the Pittsburgh suburban district further out into Butler County.
No. Just no. That was done for two very good reasons. The northernmost township of York is a fast growing suburb of Harrisburg, and the Cumberland-Franklin line splits Shippensburg in two. [/quote]
Almost all of the population in Shippensburg is in Cumberland County, so you have come across the county line to put the town in a district dominated by York County. I'd guess that the university gets a relatively large part of its student body from Harrisburg.
I suspect that Newberry has had more population growth than Fairview as both lie along the interstate south of Harrisburg. So you have split the high growth areas.
Easily possible and not affecting many people. Just gonna look damn ugly.[/quote]
That is saying that Centre County has an odd eastern extension where Clinton County includes areas along the West Branch of the Susquehanna. What if you included all of Clearfield in the northern district, put all of Centre in the brown district and pushed the blue district a bit more north?
To deny effective representation to voters in the northern parts of the two counties?
Not the ones in Delaware - one keeps very heavily Black areas just outside the town limits (and bordering just as Black areas of Philly) in with the Philly Black seat, and the other is caused by following the instruction to move the Main Line towns in with Lower MontCo (and by the desire to split no towns except Philly and Upper Darby.) They could theoretically be removed without much change elsewhere. And cyan could also be gotten out of Chester without serious remap - it just forces a less sensible split of MontCo (and/or a split town there). It's still the most reasonable one of your suggestions.

The others are quite reasonable. This one is just eminently so.
I didn't object to the split of Delaware and Chester counties, just the three and four way splits. It is the Montco seat lapping into those counties that is the extraneous district. I was suggesting extending the Philadelphia district further into Delaware county. Can you get to the city of Chester?
The Bucks plus a bit of Philadelphia district makes sense in isolation. I have seen similar situations where a district would have almost an ideal population, but it ends up forcing all kinds of other compromises.
A Berks plus outer Montco and Bucks would make a lot of sense.
So you would have:
York 435, Chester 259
Chester 240, Delaware 454
Delaware 106, Philadelphia 588
Philadelphia 694
Philadelphia 244, Bucks 449
Bucks 176, Berks 411, Montgomery 106
Montgomery 694
So you keep the two Philadelphia seats; 3 suburban districts, one each for Bucks, Montgomery, and Delaware-Chester; and two exurban districts which are dominated by an smaller city, York and Reading (3 exurban if you include the Lehigh Valley).
The northern district is not going to look pretty no matter what you do, because it doesn't have any cities. You aren't doing any favors by chopping up lots of counties.
What if you bring the green district into Carbon (or maybe Northampton), pushing the blue district out of Carbon, but further north in Lycoming, and then moving part of Wayne into the northern district.
