>Everything north of ~~Westchester~~ the speaker is Upstate.

FTFY

Similar phenomenon occurs in England, where "the north" and "the south" always begin to the north/south of whoever is being asked. <https://www.youtube.com/watch?v=ENeCYwms-Cc>

I think the concept is everywhere.

Like everything south of 175th Street in Chicagoland is Downstate Illinois. Indianapolis is in the center of Indiana, so they call everything outside the inner ring of suburbs {first half of city name}-tucky, as in a pejorative reference to Kentucky.

...and Upstate is divided into lots of different regions, like Western New York, and Central New York, as we're talking about here:

I’ve taken this concept to its fullest conclusion: everything north of the Long Beach Bridge (or Cross Bay Bridge if you live there) is “upstate”.

That’s only if you’re from Westchester. If you’re from the city, Westchester is considered upstate.

Respectful disagree. Upstate and downstate are relative terms meaning "further from / closer to NYC than wherever I live", everywhere but Long Island (which is a separate category entirely.)
