Polk lands in the national county income distribution as above-median household income on low-population county footing (FIPS 31143, 4 ZIPs, combined population 4,853). 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 (68666) 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 Nebraska, Logan is the closest lower-income county and Boone the closest higher-income county by average ZIP household income. Their 1 and 5 ZIP footprints are the immediate statewide comparison set for Polk. Use those locations as statewide context before treating the county average as a local-market answer.
