Idaho's headline economic numbers gleam: rising wages, low unemployment, a growth rate that consistently ranks among the nation's fastest. Beneath the gloss, though, is a quieter story about what that growth costs the people already here.

Housing is the sharpest edge. A decade of in-migration has pushed home prices and rents well beyond what local incomes alone would support, and the gap has forced service workers — the nurses, teachers, and tradespeople the boom depends on — toward the valley's outer edges and longer commutes.

The strain shows up in the data on household budgets, where the share of income going to shelter has climbed steadily even as paychecks grew. Economists call it a cost-of-living catch-up; residents call it a squeeze.

State leaders tout the boom as vindication of Idaho's model. For a substantial slice of the population, the boom and the burden are the same thing.
