Harper lands in the national county income distribution as below-median household income on low-population county footing (FIPS 40059, 4 ZIPs, combined population 3,985). 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 (73848), not the county mean. This page exists to join FIPS 40059 to HUD/FBI tables once the ZIP is chosen.
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.
