Thurston ZIP codes — Thurston County, Washington

Thurston County is a mid-size city in Washington, with 296,640 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 39.8 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Thurston County earn a median of $93,985 a year, 19.7% 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 9.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Thurston County is valued at $451,500, 48.8% above the national figure, while median gross rent runs $1,634 a month, 16.2% above the national figure, or roughly $19,608 across a full year. A household on the local median income would put about 20.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.8×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 67.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
