The company I work for has a published map with pay tiers on it. It's all admittedly a bit arbitrary and they are always careful to repeat often that employee pay does NOT scale with nor adjusted for the cost of living in your location, or inflation. (Basically to communicate that all raises are given based on merit and performance alone.)

Nevertheless, the highest tiers on the map are of course on the coasts, with mid-level tiers being parts of Colorado, Texas, Florida, etc. And the lowest tiers reside in flyover country where I live. But they say if you DO move permanently from one tier to another, your pay will be adjusted accordingly.
