Fairwood (King Co.), WA population, income and ZIP codes

Fairwood CDP (King County) is a mid-size town in Washington, with 18,437 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #79 of 639 ranked by population — larger than 87% of them. The median age here is 38.5 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 Fairwood CDP (King County) earn a median of $119,013 a year, 51.5% above the national figure of $78,538 and 31% above the $90,592 median for the 393 Washington cities we cover. 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 9.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Fairwood CDP (King County) is valued at $658,000, 116.9% above the national figure and 40% above the $468,400 peer median, while median gross rent runs $2,152 a month, 53.1% above the national figure, or roughly $25,824 across a full year. A household on the local median income would put about 21.7% 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 5.5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 75.9% 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.

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.
