This is a small place, and the figures below carry wide margins.
The American Community Survey reaches St. Clair through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 37 with a margin of error of plus or minus 40, which is 108.1 percent of the estimate itself. Every figure whose margin reaches 20 percent is printed with that margin beside it, so you can see the width of each one rather than having to assume it. Because the margin here exceeds the estimate, this page shows its strongest sections only rather than a full profile.
Nothing has been removed or adjusted. These are the published federal estimates, shown with the uncertainty the Census publishes alongside them.

Blair County, not St. Clair
Blair County context, not St. Clair figures
These are Blair County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as St. Clair measurements.
- Establishments in Blair County3,178
- Employment at those establishments, Blair County53,149
- Covered employment, Blair County58,025
- Average annual pay, Blair County$53,266
- Average weekly wage, Blair County$1,024
- Housing units permitted, Blair County87
- Of those, single family, Blair County69
- County product, 2024, Blair County$8,000,149,000
- County product change over the prior year, Blair County4.2 percent
- Average income of an arriving household, Blair County$59,100
Every figure in this section is published for Blair County as a whole and is not a measurement of St. Clair. It is here because a county backdrop is what a credit committee reads a place against, and it is labelled so that it can never be quoted as the place's own.

Coverage
What this page does not hold.
Every item below could be filled with a plausible figure. None of them is. On a page a lender may read, a number that cannot be traced is worse than an absence, so the absences are named.
- No SBA figures are shown. withheld: Pennsylvania has 2 places named St. Clair and the tape records none of their loans in Blair County.
- The American Community Survey does not publish a median household income for this place, which happens where the sample is too small to support one.
- No median gross rent is published for this place.
- Parcel level detail, zoning and flood zone at an address are resolved in the platform, not on this page.
SBA figures count approvals to borrowers whose address is in the place. They are not approvals for projects inside the place boundary: the tape records a borrower city and a project county, and those can differ.
Common questions
St. Clair questions, answered from the record.
How many people live in St. Clair, Pennsylvania?
37, in 12 households. St. Clair CDP covers 0.03 square miles of land, which is 1,160 people per square mile. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.
What county is St. Clair in?
Blair County, which holds 100.0 percent of the place by area. Source: US Census Bureau, cartographic boundary file, places, 2024 vintage.
Is St. Clair in the National Flood Insurance Program?
Yes. St. Clair appears in the FEMA Community Status Book as community 420786, with no Community Rating System class, so no CRS discount applies. Whether a specific parcel sits in a mapped special flood hazard area is an address level question the platform answers.
Are the county figures on this page St. Clair figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Blair County as a whole and there is no place level equivalent. They appear in one clearly marked section as context and are never presented as measurements of St. Clair.
Is zoning published for St. Clair?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
