Winnebago ZIP codes — Winnebago County, Wisconsin

Winnebago County is a mid-size city in Wisconsin, with 171,357 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 38.4 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Winnebago County earn a median of $72,873 a year, 7.2% below the national figure of $78,538. 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 10.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Winnebago County is valued at $208,600, 31.2% below the national figure, while median gross rent runs $924 a month, 34.3% below the national figure, or roughly $11,088 across a full year. A household on the local median income would put about 15.2% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65.8% 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.

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.
