Fort Knox, KY population, income and ZIP codes

Fort Knox CDP is a mid-size town in Kentucky, with 8,715 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #54 of 554 ranked by population — larger than 90% of them. The median age here is 24.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Fort Knox CDP earn a median of $74,224 a year, 5.5% below the national figure of $78,538 and 34% above the $55,469 median for the 246 Kentucky cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Fort Knox CDP is valued at not published, while median gross rent runs $1,234 a month, 12.2% below the national figure, or roughly $14,808 across a full year. A household on the local median income would put about 20% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 0.7% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 24.3 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 home value for Fort Knox CDP 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.
