ZIP code 53931

ZIP 53931 is a very small community in Fond du Lac County, Wisconsin, with 368 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #713 of 783 ranked by population — larger than 8% of them. The median age here is 30.9 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 ZIP 53931 earn a median of $81,667 a year, 4% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 22.3% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in ZIP 53931 is valued at $130,200, 57.1% below the national figure, while median gross rent runs $1,100 a month, 21.8% below the national figure, or roughly $13,200 across a full year. A household on the local median income would put about 16.2% 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 1.6×, 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. 82.6% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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. With 368 residents, a handful of survey responses moves every median on this page. Compare ZIP 53931 against its county rather than against national figures.

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.

ZIP 53931 is tabulated inside Fond du Lac County, Wisconsin, one of 15 ZIP areas the Census publishes for that county and 783 across Wisconsin. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 53931 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 53931 reports a median household income of $81,667, 7% below the $87,885 county median, and 11% above the $73,420 typical WI ZIP. Owner-occupied homes are valued at a median of $130,200, 46% below the county figure and 39% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,100 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Wisconsin charges 5% statewide, and local governments overlapping 53931 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 53931 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
