( August 2014 ) Tri-state area is an informal term in the eastern contiguous United States for any of several regions associated with a particular town or metropolis that, with adjacent suburbs, lies across three states. Some of these involve a state boundary tripoint. Other tri-state areas have a more diffuse population that shares a connected economy and geography -- especially with respect to geology, botany, or climate -- such as the tri-state area of New York, New Jersey, and Connecticut. The term `` tri-state area '' often occurs in movies and radio and television commercials.
