Karns CDP, TN in context

How this area compares with national benchmarks.

Karns CDP is a small town in Tennessee, with 3,835 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #137 of 504 ranked by population — larger than 72% of them. The median age here is 39.2 years against 39.1 nationally, a slightly older 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 Karns CDP earn a median of $101,161 a year, 28.8% above the national figure of $78,538 and 81% above the $55,988 median for the 307 Tennessee 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 4.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Karns CDP is valued at $284,700, 6.2% below the national figure and 49% above the $191,100 peer median, while median gross rent runs $1,793 a month, 27.5% above the national figure, or roughly $21,516 across a full year. A household on the local median income would put about 21.3% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 76.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
