ZIP code 40037

ZIP 40037 is a small town in Marion County, Kentucky, with 2,922 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #266 of 779 ranked by population — larger than 65% of them. The median age here is 36.6 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 40037 earn a median of $72,708 a year, 7.4% 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 9.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 40037 is valued at $212,100, 30.1% below the national figure, while median gross rent runs $726 a month, 48.4% below the national figure, or roughly $8,712 across a full year. A household on the local median income would put about 12% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 94.9% 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.

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 40037 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
