Chain Lake, WA population, income and ZIP codes

Chain Lake CDP is a small town in Washington, with 4,989 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #196 of 639 ranked by population — larger than 69% of them. The median age here is 44.2 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Chain Lake CDP earn a median of $148,932 a year, 89.6% above the national figure of $78,538 and 64% above the $90,592 median for the 393 Washington cities we cover. 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Chain Lake CDP is valued at $830,200, 173.6% above the national figure and 77% above the $468,400 peer median, while median gross rent runs $1,728 a month, 22.9% above the national figure, or roughly $20,736 across a full year. A household on the local median income would put about 13.9% 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 5.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 88.4% 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.

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.
