Gilliam lands in the national county income distribution as above-median household income on low-population county footing (FIPS 41021, 2 ZIPs, combined population 1,799). 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 (97823) as the primary ACS record and this county page as the FIPS bridge. Intra-county contrast is limited by construction.
Combined population stays under five thousand - this is a thin rural FIPS. Bookmark one ZIP; a multi-ZIP shortlist rarely adds signal beyond the primary code's ACS row.
Within Oregon, Jackson is the closest lower-income county and Klamath the closest higher-income county by average ZIP household income. Their 15 and 14 ZIP footprints are the immediate statewide comparison set for Gilliam. Use those locations as statewide context before treating the county average as a local-market answer.
