Walla Walla ZIP codes — Walla Walla County, Washington

Walla Walla County is a small city in Washington, with 62,102 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 38.3 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Walla Walla County earn a median of $72,212 a year, 8.1% below the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 11.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Walla Walla County is valued at $375,600, 23.8% above the national figure, while median gross rent runs $1,113 a month, 20.8% below the national figure, or roughly $13,356 across a full year. A household on the local median income would put about 18.5% 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 5.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 65.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
