ZIP code 47557

ZIP 47557 is a small town in Knox County, Indiana, with 1,360 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #535 of 807 ranked by population — larger than 33% of them. The median age here is 34 years against 39.1 nationally, a slightly younger 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 47557 earn a median of $80,833 a year, 2.9% above 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 21% 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 47557 is valued at $151,500, 50.1% below the national figure, while median gross rent runs $1,017 a month, 27.7% below the national figure, or roughly $12,204 across a full year. A household on the local median income would put about 15.1% 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 1.9×, 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. 77.7% 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.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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 47557 is tabulated inside Knox County, Indiana, one of 12 ZIP areas the Census publishes for that county and 807 across Indiana. 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 47557 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 47557 reports a median household income of $80,833, 38% above the $58,654 county median, and 17% above the $68,990 typical IN ZIP.

Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,017 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Indiana charges 7% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 47557.

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 47557 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.
