Colby city, WI in context

How this area compares with national benchmarks.

Colby city is a small town in Wisconsin, with 2,118 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #263 of 807 ranked by population — larger than 67% of them. The median age here is 38.2 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 Colby city earn a median of $52,574 a year, 33.1% below the national figure of $78,538 and 29% below the $73,880 median for the 395 Wisconsin 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 16% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Colby city is valued at $147,900, 51.3% below the national figure and 30% below the $211,900 peer median, while median gross rent runs $821 a month, 41.6% below the national figure, or roughly $9,852 across a full year. A household on the local median income would put about 18.7% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 56.9% 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
