Mattawa, WA population, income and ZIP codes

Mattawa city is a small town in Washington, with 3,553 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #236 of 639 ranked by population — larger than 63% of them. The median age here is 22.5 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Mattawa city earn a median of $41,250 a year, 47.5% below the national figure of $78,538 and 54% 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 25.4% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Mattawa city is valued at not published, while median gross rent runs $1,089 a month, 22.5% below the national figure, or roughly $13,068 across a full year. A household on the local median income would put about 31.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. 28.2% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

A median age of 22.5 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

The Census withheld home value for Mattawa city 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.
