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

Walnut Grove CDP (Sumner County) is a very small community in Tennessee, with 576 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #367 of 504 ranked by population — larger than 27% of them. The median age here is 54.7 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 (Sumner County) earn a median of $123,063 a year, 56.7% above the national figure of $78,538 and 120% 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.

The typical owner-occupied home in Walnut Grove CDP (Sumner County) is valued at $476,400, 57% above the national figure and 149% above the $191,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 89.1% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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 54.7 puts Walnut Grove CDP (Sumner County) well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 576 residents, a handful of survey responses moves every median on this page. Compare Walnut Grove CDP (Sumner County) against its county rather than against national figures.

The Census withheld gross rent for Walnut Grove CDP (Sumner 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.
