ZIP code 40228

ZIP 40228 is a mid-size town in Jefferson County, Kentucky, with 18,491 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #84 of 779 ranked by population — larger than 89% of them. The median age here is 39.5 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 40228 earn a median of $75,762 a year, 3.5% 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 7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 40228 is valued at $220,200, 27.4% below the national figure, while median gross rent runs $1,370 a month, 2.6% below the national figure, or roughly $16,440 across a full year. A household on the local median income would put about 21.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 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. 79.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.

ZIP 40228 is tabulated inside Jefferson County, Kentucky, one of 38 ZIP areas the Census publishes for that county and 779 across Kentucky. This is a mid-sized suburban ZIP inside a county that is split across many delivery areas. 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 40228 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 40228 reports a median household income of $75,762, 9% above the $69,640 county median, and 41% above the $53,906 typical KY ZIP. Owner-occupied homes are valued at a median of $220,200, close to the county figure and 68% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,370 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 40228.

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 40228 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.
