Prairie Heights, WA population, income and ZIP codes

Prairie Heights CDP is a small town in Washington, with 4,817 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #202 of 639 ranked by population — larger than 68% of them. The median age here is 40.5 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 Prairie Heights CDP earn a median of $129,438 a year, 64.8% above the national figure of $78,538 and 43% above the $90,592 median for the 393 Washington cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 2.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Prairie Heights CDP is valued at $485,800, 60.1% above the national figure and 4% above the $468,400 peer median, while median gross rent runs $1,859 a month, 32.2% above the national figure, or roughly $22,308 across a full year. A household on the local median income would put about 17.2% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 95.5% 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.

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.
