ZIP code 57375

ZIP 57375 is a very small community in Aurora County, South Dakota, with 590 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #192 of 375 ranked by population — larger than 48% of them. The median age here is 40 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 57375 earn a median of $73,333 a year, 6.6% 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 10.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 57375 is valued at $143,300, 52.8% below the national figure, while median gross rent runs $714 a month, 49.2% below the national figure, or roughly $8,568 across a full year. A household on the local median income would put about 11.7% 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×, 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. 78% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 590 residents, a handful of survey responses moves every median on this page. Compare ZIP 57375 against its county rather than against national figures.

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.

ZIP 57375 is tabulated inside Aurora County, South Dakota, one of 3 ZIP areas the Census publishes for that county and 375 across South Dakota. 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 57375 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 57375 reports a median household income of $73,333, close to the $73,333 county median, and close to the $71,607 typical SD ZIP. Owner-occupied homes are valued at a median of $143,300, close to the county figure and 12% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $714 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

South Dakota charges 4.2% statewide, and local governments overlapping 57375 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 57375 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.
