ZIP code 57577

ZIP 57577 is a small town in Jackson County, South Dakota, with 1,100 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #127 of 375 ranked by population — larger than 66% of them. The median age here is 27.7 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 57577 earn a median of $23,714 a year, 69.8% 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 44.2% 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 57577 is valued at $58,800, 80.6% below the national figure, while median gross rent runs $405 a month, 71.2% below the national figure, or roughly $4,860 across a full year. A household on the local median income would put about 20.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 40.8% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

A median age of 27.7 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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 57577 is tabulated inside Jackson County, South Dakota, one of 4 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 57577 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 57577 reports a median household income of $23,714, 11% below the $26,771 county median, and 67% below the $71,607 typical SD ZIP. Owner-occupied homes are valued at a median of $58,800, 47% below the county figure and 64% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $405 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 57577 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 57577 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.
