A meaningfully above-national retiree population share

Spearfish's 65+ population share (20.7%) runs meaningfully above the national average, with a median age (40.0) modestly above South Dakota's own statewide figure (~37.7-38.5, per south-dakota.js) -- real, independently found support for this record's RETIREE_POPULATION tag.

South Dakota's real, favorable statewide tax structure

No state individual income tax applies fully to Spearfish retirees, though the town's own elevated property values mean a higher dollar tax bill than a lower-value SD town at the same statewide rate.

A real, disclosed housing-cost premium

Spearfish's average home value (~$413,219) runs approximately 29% above South Dakota's statewide average -- retirees relocating on a fixed income should budget accordingly.
