ZIP code 42123

ZIP 42123 is a small town in Barren County, Kentucky, with 1,203 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #416 of 779 ranked by population — larger than 46% of them. The median age here is 30 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 42123 earn a median of $36,607 a year, 53.4% 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 16.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 42123 is valued at $115,200, 62% below the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 79.7% 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.

A median age of 30 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.

The Census withheld gross rent for ZIP 42123 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.

ZIP 42123 is tabulated inside Barren County, Kentucky, one of 6 ZIP areas the Census publishes for that county and 779 across Kentucky. 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 42123 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 42123 reports a median household income of $36,607, 22% below the $47,189 county median, and 32% below the $53,906 typical KY ZIP. Owner-occupied homes are valued at a median of $115,200, 36% below the county figure and 12% below 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 42123.

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 42123 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.
