ZIP 42157 in context

How this area compares with national benchmarks.

ZIP 42157 is a very small community in Monroe County, Kentucky, with 487 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #592 of 779 ranked by population — larger than 24% of them. The median age here is 37.9 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 42157 earn a median of $97,946 a year, 24.7% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 27.1% 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 42157 is valued at $155,100, 48.9% below the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.6×, 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. 77.9% 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.

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. With 487 residents, a handful of survey responses moves every median on this page. Compare ZIP 42157 against its county rather than against national figures.

The Census withheld gross rent for ZIP 42157 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

Reading ZIP 42157 in context

How 42157 sits inside Monroe County and Kentucky.

ZIP 42157 is tabulated inside Monroe County, Kentucky, one of 5 ZIP areas the Census publishes for that county and 779 across Kentucky. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. 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 42157 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 42157 reports a median household income of $97,946, 98% above the $49,361 county median, and 82% above the $53,906 typical KY ZIP. Owner-occupied homes are valued at a median of $155,100, 11% above the county figure and 19% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Kentucky charges 6% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 42157.

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 42157 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.
