I never thought of "sunbelt" as a specific geographic region but rather a cluster of cities that shared common characteristics such as rather sunny and warm weather, explosive post-war growth, and a destination for retirees. As others have pointed out, they're lots of cities in the sunbelt "region" such as Jackson, MS or Montgomery no one would consider sun belt so I'm not sure arguing over geographic characteristics makes sense. And if we were, than we'd definitely want to include places like St. George, Denver, Yuma- i.e., the sunniest places in the US.
