ZIP 42451 in context
How this area compares with national benchmarks.
ZIP 42451 is a very small community in Henderson County, Kentucky, with 448 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #606 of 779 ranked by population — larger than 22% of them. The median age here is 28.4 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 42451 earn a median of $56,667 a year, 27.8% below the national figure of $78,538. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 40.4% 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 42451 is valued at not published, while median gross rent runs not published a month. 61.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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 28.4 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. With 448 residents, a handful of survey responses moves every median on this page. Compare ZIP 42451 against its county rather than against national figures.
The Census withheld home value, gross rent for ZIP 42451 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.
