ZIP code 99301

ZIP 99301 is a small city in Franklin County, Washington, with 86,467 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it first of 605 ranked by population. The median age here is 30.5 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in ZIP 99301 earn a median of $82,517 a year, 5.1% 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 13.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 99301 is valued at $353,300, 16.4% above the national figure, while median gross rent runs $1,195 a month, 15% below the national figure, or roughly $14,340 across a full year. A household on the local median income would put about 17.4% 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 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 69.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.

Washington charges 6.5% statewide, and local governments overlapping 99301 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 99301 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.
