I have never called any part of PA upstate. (Not that it’s wrong that you do) Everyone I know calls the northern half of the eastern third of the state “the Northeast” or NEPA. Western PA is the entire western third of the state, and Central PA is for some reason only the southern half of the middle third of the state. I guess maybe the northern half of the middle third could be upstate, but I think I just don’t have a word for it.
