Sammamish, WA population, income and ZIP codes

Sammamish city is a small city in Washington, with 66,375 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #20 of 639 ranked by population — larger than 97% of them. The median age here is 39.4 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 Sammamish city earn a median of $227,273 a year, 189.4% above the national figure of $78,538 and 151% above the $90,592 median for the 393 Washington cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 4.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Sammamish city is valued at $1,240,300, 308.8% above the national figure and 165% above the $468,400 peer median, while median gross rent runs $2,728 a month, 94% above the national figure, or roughly $32,736 across a full year. A household on the local median income would put about 14.4% 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 5.5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 83.4% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
