St. Clair CDP, PA population, income and ZIP codes

St. Clair CDP is a very small community in Pennsylvania, with 37 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1969 of 2,002 ranked by population — larger than 1% of them. The median age here is 31.6 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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. Clair CDP earn a median of not published a year. 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 56.8% 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 St. Clair CDP is valued at not published, while median gross rent runs not published a month. 100% 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.

With 37 residents, a handful of survey responses moves every median on this page. Compare St. Clair CDP against its county rather than against national figures.

The Census withheld household income, home value, gross rent for St. Clair CDP 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.
