Oskaloosa, KS population, income and ZIP codes

Oskaloosa city is a small town in Kansas, with 1,172 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #183 of 740 ranked by population — larger than 75% of them. The median age here is 36.6 years against 39.1 nationally, a slightly younger 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 Oskaloosa city earn a median of $79,250 a year, essentially level with the national figure of $78,538 and 24% above the $63,750 median for the 200 Kansas 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 14.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Oskaloosa city is valued at $145,000, 52.2% below the national figure and 10% above the $131,300 peer median, while median gross rent runs $863 a month, 38.6% below the national figure, or roughly $10,356 across a full year. A household on the local median income would put about 13.1% 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 1.8×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 78.1% 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.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

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.
