Baldwin City, KS population, income and ZIP codes

Baldwin City city is a small town in Kansas, with 4,881 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #66 of 740 ranked by population — larger than 91% of them. The median age here is 29.9 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 Baldwin City city earn a median of $81,838 a year, 4.2% above the national figure of $78,538 and 28% above the $63,750 median for the 200 Kansas cities we cover. 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 4.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Baldwin City city is valued at $242,100, 20.2% below the national figure and 84% above the $131,300 peer median, while median gross rent runs $1,020 a month, 27.5% below the national figure, or roughly $12,240 across a full year. A household on the local median income would put about 15% 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×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 68.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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 29.9 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.

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.
