Fresh.Data current as of Apr 24, 2026
WA 99346 (ZIP 99346) sits in Benton County within the Kennewick-Richland metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Obesity comes in above the national average at 41.0%. No NCES schools are mapped to this ZIP in the current dataset. 8 colleges and universities serve the area, with median in-state tuition of $11,806. Average annual pay across local establishments runs $86,860 per worker (Census ZBP) — a high-wage local economy. CDC's Social Vulnerability Index places this ZIP in the 86th percentile nationally — a highly vulnerable community profile. FEMA has issued 20 federal disaster declarations affecting this ZIP since 1964 — a high-frequency exposure profile. Annual precipitation averages just 8.6" per NOAA's 1991–2020 Normals — an arid-climate ZCTA where landscaping and water-budget choices matter more than national averages suggest. Fast-food restaurants outnumber grocery stores roughly 6-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. Washington has no state income tax (Tax Foundation 2025). New residents arriving here predominantly come from Franklin County, WA (IRS SOI Migration, 2022-2023). Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: median household income $61,944, fair market rent of $1,490 for a two-bedroom, and a median home value of $223,600. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

Both surfaces skew lighter than national averages. That isn’t a verdict — small-area estimates compress real neighborhood-level texture, and a single ZIP reading can miss a district line or a hospital corridor sitting just outside it. Treat this as a starting point for fieldwork, not a conclusion.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 23.8%. 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.

Tract-level scores are aggregated to this ZCTA via Census 2020 ZCTA→Tract crosswalk, weighted by land-area share. Source: atsdr.cdc.gov. Public domain.
