A curated dataset of colloquial geographic regions in the United States — places like Cape Cod, the Ozarks, or the Texas Hill Country that people actually use in speech but that don't appear as administrative boundaries.
The Mapbox geocoder covers cities, counties, states, and postal codes well, but largely misses the informal regional names that people use in everyday conversation. Someone saying "I'm heading to the Jersey Shore" or "I grew up in Appalachia" is referring to a real, well-understood place — just not one with an official boundary. This dataset is a first step toward filling that gap.
