Q: How do I force Photos (iOS 7) to show U.S. state instead of informal region?

The photos grouping on iOS 7.1.2 on my ipad mini (wifi+cellular) doesn't always show the U.S. state for the location. Even though all the photos in a given collection (or given date), it will show the location as "[City], Bible Belt" instead of "[City, State]". I find this very annoying. At the level of individual dates, it usually does show the correct state. But where the heck does this "Bible Belt" location come from, and how to get rid of it (or something actually geographic, like Southern Plains)? Is ios 8 any better about this? Location services appears to be just an on/off thing.
