ZIP code 99345

ZIP 99345 is a very small community in Benton County, Washington, with 169 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #552 of 605 ranked by population — larger than 8% of them. The median age here is 41.9 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 99345 earn a median of $111,250 a year, 41.7% above the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 11.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 99345 is valued at $422,200, 39.2% above the national figure, while median gross rent runs $441 a month, 68.6% below the national figure, or roughly $5,292 across a full year. A household on the local median income would put about 4.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 61.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 169 residents, a handful of survey responses moves every median on this page. Compare ZIP 99345 against its county rather than against national figures.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.

ZIP 99345 is tabulated inside Benton County, Washington, one of 11 ZIP areas the Census publishes for that county and 605 across Washington. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 99345 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 99345 reports a median household income of $111,250, 26% above the $88,601 county median, and 38% above the $80,861 typical WA ZIP. Owner-occupied homes are valued at a median of $422,200, 19% above the county figure and close to the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $441 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Washington charges 6.5% statewide, and local governments overlapping 99345 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 99345 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
