Onalaska, WA population, income and ZIP codes

Onalaska CDP is a very small community in Washington, with 657 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #443 of 639 ranked by population — larger than 30% of them. The median age here is 28 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 Onalaska CDP earn a median of not published a year. 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 13.7% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Onalaska CDP is valued at $412,800, 36.1% above the national figure and 12% below the $468,400 peer median, while median gross rent runs $910 a month, 35.3% below the national figure, or roughly $10,920 across a full year. 54.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 28 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. With 657 residents, a handful of survey responses moves every median on this page. Compare Onalaska CDP against its county rather than against national figures.

The Census withheld household income for Onalaska CDP 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.
