Waterville, WA population, income and ZIP codes

Waterville town is a small town in Washington, with 1,353 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #361 of 639 ranked by population — larger than 43% of them. The median age here is 48 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 Waterville town earn a median of $75,854 a year, 3.4% below the national figure of $78,538 and 16% 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 6.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Waterville town is valued at $247,300, 18.5% below the national figure and 47% below the $468,400 peer median, while median gross rent runs $1,533 a month, 9% above the national figure, or roughly $18,396 across a full year. A household on the local median income would put about 24.3% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 79.5% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
