ZIP 37620 in context
How this area compares with national benchmarks.
ZIP 37620 is a small city in Sullivan County, Tennessee, with 38,330 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #45 of 638 ranked by population — larger than 93% of them. The median age here is 44.7 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 37620 earn a median of $54,908 a year, 30.1% below the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 12.5% of residents here, above the 12.4% national rate.
The typical owner-occupied home in ZIP 37620 is valued at $175,500, 42.2% below the national figure, while median gross rent runs $809 a month, 42.5% below the national figure, or roughly $9,708 across a full year. A household on the local median income would put about 17.7% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 71.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
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.
Reading ZIP 37620 in context
How 37620 sits inside Sullivan County and Tennessee.
ZIP 37620 is tabulated inside Sullivan County, Tennessee, one of 8 ZIP areas the Census publishes for that county and 638 across Tennessee. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. 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 37620 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 37620 reports a median household income of $54,908, 8% below the $59,789 county median, and 7% below the $59,143 typical TN ZIP. Owner-occupied homes are valued at a median of $175,500, 8% below the county figure and 10% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $809 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 37620 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 37620 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.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
