ZIP 37915 in context

How this area compares with national benchmarks.

ZIP 37915 is a mid-size town in Knox County, Tennessee, with 6,124 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #270 of 638 ranked by population — larger than 57% of them. The median age here is 31.7 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 ZIP 37915 earn a median of $22,236 a year, 71.7% 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 45.3% 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 37915 is valued at $206,400, 32% below the national figure, while median gross rent runs $519 a month, 63.1% below the national figure, or roughly $6,228 across a full year. A household on the local median income would put about 28% 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 9.3×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 24.2% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

Home values sit at 9.3× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

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.

Reading ZIP 37915 in context

How 37915 sits inside Knox County and Tennessee.

ZIP 37915 is tabulated inside Knox County, Tennessee, one of 23 ZIP areas the Census publishes for that county and 638 across Tennessee. Population sits in the small-town band, typically one main street plus the addresses that feed into it. 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 37915 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 37915 reports a median household income of $22,236, 67% below the $66,993 county median, and 62% below the $59,143 typical TN ZIP. Owner-occupied homes are valued at a median of $206,400, 18% below the county figure and 6% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $519 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Tennessee charges 7% statewide, and local governments overlapping 37915 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

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 37915 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.
