Where the Premium Lives in South Dakota
Sioux Falls, SD-MN and Rapid City, SD form a photo finish at the top, separated by only 1.5 RPP points. The useful signal is the cluster rather than the nominal first-place label; small release revisions could change their order without changing the state's expensive-market tier.
Housing is the component furthest from the national benchmark in Sioux Falls, SD-MN, but it remains below 100 at 77.6. In this state, “most expensive” can still mean least affordable only relative to nearby metros, not expensive compared with the country.
