Johnson ZIP codes — Johnson County, Tennessee

Johnson County is a mid-size town in Tennessee, with 18,073 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 46.4 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Johnson County earn a median of $52,152 a year, 33.6% below the national figure of $78,538. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 22.1% 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 Johnson County is valued at $175,500, 42.2% below the national figure, while median gross rent runs $639 a month, 54.6% below the national figure, or roughly $7,668 across a full year. A household on the local median income would put about 14.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 78.6% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
