Columbia lands in the national county income distribution as below-median household income on low-population county footing (FIPS 53013, 2 ZIPs, combined population 3,891). 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 (99328), not the county mean. This page exists to join FIPS 53013 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.
Within Washington, Grays Harbor is the closest lower-income county and Okanogan the closest higher-income county by average ZIP household income. Their 16 and 19 ZIP footprints are the immediate statewide comparison set for Columbia. Use those locations as statewide context before treating the county average as a local-market answer.
