St. Petersburg, PA population, income and ZIP codes

St. Petersburg borough is a very small community in Pennsylvania, with 256 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1638 of 2,002 ranked by population — larger than 18% of them. The median age here is 54.2 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 St. Petersburg borough earn a median of $59,792 a year, 23.9% below the national figure of $78,538 and 16% below the $71,118 median for the 982 Pennsylvania cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 8.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in St. Petersburg borough is valued at $92,100, 69.6% below the national figure and 52% below the $193,200 peer median, while median gross rent runs $1,050 a month, 25.3% below the national figure, or roughly $12,600 across a full year. A household on the local median income would put about 21.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 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. 82.6% 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. 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.

A median age of 54.2 puts St. Petersburg borough 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 256 residents, a handful of survey responses moves every median on this page. Compare St. Petersburg borough 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.
