ZIP code 57105

ZIP 57105 is a mid-size town in Minnehaha County, South Dakota, with 22,764 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #10 of 375 ranked by population — larger than 97% of them. The median age here is 37.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 57105 earn a median of $74,066 a year, 5.7% 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 8.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 57105 is valued at $247,900, 18.3% below the national figure, while median gross rent runs $956 a month, 32% below the national figure, or roughly $11,472 across a full year. A household on the local median income would put about 15.5% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

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 57105 is tabulated inside Minnehaha County, South Dakota, one of 19 ZIP areas the Census publishes for that county and 375 across South Dakota. This is a mid-sized suburban ZIP inside a county that is split across many delivery areas. 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 57105 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 57105 reports a median household income of $74,066, 25% below the $98,156 county median, and 3% above the $71,607 typical SD ZIP. Owner-occupied homes are valued at a median of $247,900, 9% below the county figure and 53% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $956 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 57105 carries 6.2% at the register, assembled from the Sioux Falls jurisdiction stack: the South Dakota state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 57105 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

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 57105 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.
