Sunday Lake, WA population, income and ZIP codes

Sunday Lake CDP is a small town in Washington, with 1,209 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #369 of 639 ranked by population — larger than 42% of them. The median age here is 41 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 Sunday Lake CDP earn a median of $110,491 a year, 40.7% above the national figure of $78,538 and 22% 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 9.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Sunday Lake CDP is valued at $696,700, 129.6% above the national figure and 49% above the $468,400 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 6.3×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 85.6% 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. 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.

Home values sit at 6.3× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

The Census withheld gross rent for Sunday Lake CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
