ZIP 40870 in context
How this area compares with national benchmarks.
ZIP 40870 is a very small community in Harlan County, Kentucky, with 635 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #547 of 779 ranked by population — larger than 29% of them. The median age here is 51.7 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 40870 earn a median of $46,961 a year, 40.2% below 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 3.4% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in ZIP 40870 is valued at $128,800, 57.5% below the national figure, while median gross rent runs $648 a month, 53.9% below the national figure, or roughly $7,776 across a full year. A household on the local median income would put about 16.6% 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 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 88.1% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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 51.7 puts ZIP 40870 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 635 residents, a handful of survey responses moves every median on this page. Compare ZIP 40870 against its county rather than against national figures.
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.
Reading ZIP 40870 in context
How 40870 sits inside Harlan County and Kentucky.
ZIP 40870 is tabulated inside Harlan County, Kentucky, one of 25 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 40870 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 40870 reports a median household income of $46,961, 29% above the $36,430 county median, and 13% below the $53,906 typical KY ZIP. Owner-occupied homes are valued at a median of $128,800, 99% above the county figure and close to the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $648 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 40870.
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 40870 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.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
