Walnut Grove (Hardin Co.), TN population, income and ZIP codes

Walnut Grove CDP (Hardin County) is a very small community in Tennessee, with 467 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #395 of 504 ranked by population — larger than 21% of them. The median age here is 22.4 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Walnut Grove CDP (Hardin County) earn a median of $53,255 a year, 32.2% below the national figure of $78,538 and 5% below 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 30.8% 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 Walnut Grove CDP (Hardin County) is valued at $78,000, 74.3% below the national figure and 59% below the $191,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.5×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 71% 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.

A median age of 22.4 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. With 467 residents, a handful of survey responses moves every median on this page. Compare Walnut Grove CDP (Hardin County) against its county rather than against national figures.

The Census withheld gross rent for Walnut Grove CDP (Hardin County) 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.
