Elk Plain CDP, WA in context

How this area compares with national benchmarks.

Elk Plain CDP is a mid-size town in Washington, with 13,863 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #97 of 639 ranked by population — larger than 84% of them. The median age here is 39.3 years against 39.1 nationally, a slightly older 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 Elk Plain CDP earn a median of $101,250 a year, 28.9% above the national figure of $78,538 and 12% 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 6.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Elk Plain CDP is valued at $440,300, 45.1% above the national figure and 6% below the $468,400 peer median, while median gross rent runs $1,908 a month, 35.7% above the national figure, or roughly $22,896 across a full year. A household on the local median income would put about 22.6% 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 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 83.9% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
