Washington lands in the national county income distribution as below-median household income on sparsely populated county footing (FIPS 16087, 3 ZIPs, combined population 10,165). On this short ZIP list the county page is mainly the FIPS bridge - household ACS fields live on the primary ZIP.
Below-median income with few ZIPs: start cost-of-living reads on the primary code (83672), not the county mean. This page exists to join FIPS 16087 to HUD/FBI tables once the ZIP is chosen.
Population sits in the five-to-twenty-five thousand band with few ZIPs - still ZIP-first for household fields, but the county seat ZIP (usually the densest row) is worth a second glance before the FIPS overlays.
Within Idaho, Lemhi is the closest lower-income county and Shoshone the closest higher-income county by average ZIP household income. Their 5 and 11 ZIP footprints are the immediate statewide comparison set for Washington. Use those locations as statewide context before treating the county average as a local-market answer.
