ⓘ Twin Tiers

The Twin Tiers are the collective counties that lie on the New York-Pennsylvania border on either side of the 42nd parallel north. The region is predominantly rural and contains many small towns.

Separately, the two halves of the twin tiers region called the southern tier region in upstate new York and Northern region in the Commonwealth of Pennsylvania. "North" and "South" designations relative to the States in which they are located, not relative to each other.
