What these numbers say together
Dayton, WA (ZIP 99328) sits in Columbia County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Health Insurance comes in below the national average at 7.6%. NCES lists 4 schools serving the area, 4 non-charter. 8 colleges and universities serve the area, with median in-state tuition of $11,806. IRS data shows average household income (AGI) of $70,675, well above the ~$45K national average per return. FEMA has issued 16 federal disaster declarations affecting this ZIP since 1964. Per USDA's Food Environment Atlas, 49.1% of residents in this county live more than 1 mile (urban) or 10 miles (rural) from the nearest supermarket — a deep food-access gap. Washington has no state income tax, saving the local median household (AGI $70,675) approximately $3,251/year vs the US average effective state tax rate. IRS migration data (2022-2023) shows a net gain of 28 residents (12 households) — the ZIP's primary county is growing. 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 $69,355, fair market rent of $1,340 for a two-bedroom, and a typical home value of $265,955, down 0.7% 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.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 25.8%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
