Asotin, WA (ZIP 99402) sits in Asotin County within the Lewiston metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Health Insurance comes in below the national average at 6.0%. NCES lists 2 schools serving the area, 2 non-charter. IRS data shows average household income (AGI) of $93,109, well above the ~$45K national average per return. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. The most recent FEMA disaster declaration here was flood-related (SEVERE STORMS, STRAIGHT-LINE WINDS, FLOODING, LANDSLIDES, AND MUDSLIDES, 2026). Annual precipitation averages just 12.9" per NOAA's 1991–2020 Normals — an arid-climate ZCTA where landscaping and water-budget choices matter more than national averages suggest. Washington has no state income tax, saving the local median household (AGI $93,109) approximately $4,283/year vs the US average effective state tax rate. New residents arriving here predominantly come from Nez Perce County, ID (IRS SOI Migration, 2022-2023). Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $80,769, fair market rent of $1,300 for a two-bedroom, and a typical home value of $404,205, up 0.4% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
