South Creek, WA population, income and ZIP codes

South Creek CDP is a small town in Washington, with 1,885 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #322 of 639 ranked by population — larger than 49% of them. The median age here is 52.9 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 South Creek CDP earn a median of $81,826 a year, 4.2% above the national figure of $78,538 and 10% below the $90,592 median for the 393 Washington cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 17.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in South Creek CDP is valued at $548,800, 80.9% above the national figure and 17% above the $468,400 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 6.7×, 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. 73.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 6.7× 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. A median age of 52.9 puts South Creek CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

The Census withheld gross rent for South Creek 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.
