Coulee Dam, WA population, income and ZIP codes

Coulee Dam town is a small town in Washington, with 1,457 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #353 of 639 ranked by population — larger than 44% of them. The median age here is 42 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 Coulee Dam town earn a median of $67,868 a year, 13.6% below the national figure of $78,538 and 25% below 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 12% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Coulee Dam town is valued at $212,900, 29.8% below the national figure and 55% below the $468,400 peer median, while median gross rent runs $952 a month, 32.3% below the national figure, or roughly $11,424 across a full year. A household on the local median income would put about 16.8% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 66.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
