Snohomish ZIP codes — Snohomish County, Washington

Snohomish County is a major city in Washington, with 834,648 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 38.4 years against 39.1 nationally, a slightly younger 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 Snohomish County earn a median of $107,982 a year, 37.5% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 7.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Snohomish County is valued at $644,600, 112.5% above the national figure, while median gross rent runs $1,866 a month, 32.7% above the national figure, or roughly $22,392 across a full year. A household on the local median income would put about 20.7% 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 6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 68.4% 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.

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.
