Thanks for replying Mihnea,
However I think there may be a bit of a misunderstanding. When we mention the Tri-state area, we are referring to the NY Metropolitan Area. The NY Metropolitan Area is a region that is composed of certain cities, & counties of each state that are tied socioeconomically. Please see the image below.

As Shruthi N mentioned, the only possible solution we can observe right now would be to include every municipality and city, or zipcode within the metropolitan area. Would you happen to know of any other efficient methods that we can potentially try to reduce workload of inputting every city or zipcode?
Thanks,
Chris
