ZIP code 57365

ZIP 57365 is a very small community in Lyman County, South Dakota, with 619 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #184 of 375 ranked by population — larger than 51% of them. The median age here is 51.8 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 57365 earn a median of $63,611 a year, 19% below the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 6.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 57365 is valued at $259,300, 14.5% below the national figure, while median gross rent runs $847 a month, 39.8% below the national figure, or roughly $10,164 across a full year. A household on the local median income would put about 16% 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 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 83.5% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 51.8 puts ZIP 57365 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 619 residents, a handful of survey responses moves every median on this page. Compare ZIP 57365 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 57365 is tabulated inside Lyman County, South Dakota, one of 6 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 57365 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 57365 reports a median household income of $63,611, 3% above the $61,635 county median, and 11% below the $71,607 typical SD ZIP. Owner-occupied homes are valued at a median of $259,300, 69% above the county figure and 60% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $847 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 57365 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 57365 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.
