ZIP code 53577

ZIP 53577 is a small town in Sauk County, Wisconsin, with 1,305 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #577 of 783 ranked by population — larger than 26% of them. The median age here is 40.5 years against 39.1 nationally, a slightly older 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 ZIP 53577 earn a median of $88,750 a year, 13% above 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 8.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 53577 is valued at $247,800, 18.3% below the national figure, while median gross rent runs $970 a month, 31% below the national figure, or roughly $11,640 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 74.6% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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 53577 is tabulated inside Sauk County, Wisconsin, one of 14 ZIP areas the Census publishes for that county and 783 across Wisconsin. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. 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 53577 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 53577 reports a median household income of $88,750, close to the $86,957 county median, and 21% above the $73,420 typical WI ZIP. Owner-occupied homes are valued at a median of $247,800, close to the county figure and 16% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $970 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 53577 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 53577 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.
