St. Clair County, not Algonac
St. Clair County context, not Algonac figures
These are St. Clair County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Algonac measurements.
- Establishments in St. Clair County3,080
- Employment at those establishments, St. Clair County41,206
- Covered employment, St. Clair County42,283
- Average annual pay, St. Clair County$55,695
- Average weekly wage, St. Clair County$1,071
- Housing units permitted, St. Clair County235
- Of those, single family, St. Clair County235
- County product, 2024, St. Clair County$7,417,446,000
- County product change over the prior year, St. Clair County2.2 percent
- Average income of an arriving household, St. Clair County$60,731
Every figure in this section is published for St. Clair County as a whole and is not a measurement of Algonac. 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.
- 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.

These count approvals to borrowers whose address is in Algonac, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Algonac borrowers get paid back?
No rate is published for Algonac. only 3 resolved loans, too few to publish a rate, and a percentage over that few outcomes would move several points on a single loan. The counts are shown instead.
Is Algonac in the National Flood Insurance Program?
Yes. Algonac appears in the FEMA Community Status Book as community 260191, 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 Algonac figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for St. Clair 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 Algonac.
Is zoning published for Algonac?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
