Gem lands in the national county income distribution as above-median household income on sparsely populated county footing (FIPS 16045, 4 ZIPs, combined population 16,302). On this short ZIP list the county page is mainly the FIPS bridge - household ACS fields live on the primary ZIP.
Above-median income with few ZIPs: treat the top code (83617) as the primary ACS record and this county page as the FIPS bridge. Intra-county contrast is limited by construction.
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.
