Petersburg, TN population, income and ZIP codes

Petersburg town is a very small community in Tennessee, with 579 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #365 of 504 ranked by population — larger than 27% of them. The median age here is 43.8 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 Petersburg town earn a median of $58,942 a year, 25% below the national figure of $78,538 and 5% above the $55,988 median for the 307 Tennessee cities we cover. 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 16.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Petersburg town is valued at $144,600, 52.3% below the national figure and 24% below the $191,100 peer median, while median gross rent runs $648 a month, 53.9% below the national figure, or roughly $7,776 across a full year. A household on the local median income would put about 13.2% 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 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 64.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

With 579 residents, a handful of survey responses moves every median on this page. Compare Petersburg town against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
