This is a small place, and the figures below carry wide margins.
The American Community Survey reaches Flat Rock through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 340 with a margin of error of plus or minus 195, which is 57.4 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.
Nothing has been removed or adjusted. These are the published federal estimates, shown with the uncertainty the Census publishes alongside them.

Seneca County, not Flat Rock
Seneca County context, not Flat Rock figures
These are Seneca County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Flat Rock measurements.
- Establishments in Seneca County1,053
- Employment at those establishments, Seneca County16,258
- Covered employment, Seneca County19,092
- Average annual pay, Seneca County$49,201
- Average weekly wage, Seneca County$946
- Housing units permitted, Seneca County43
- Of those, single family, Seneca County39
- County product, 2024, Seneca County$2,753,349,000
- County product change over the prior year, Seneca County1.5 percent
- Average income of an arriving household, Seneca County$47,698
Every figure in this section is published for Seneca County as a whole and is not a measurement of Flat Rock. 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.
- This place is not listed as a community in the FEMA Community Status Book, so no NFIP participation or CRS class is shown.
- 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

340, in 110 households. Flat Rock CDP covers 0.21 square miles of land, which is 1,601 people per square mile. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.

Seneca County, which holds 100.0 percent of the place by area. Source: US Census Bureau, cartographic boundary file, places, 2024 vintage.
Are the county figures on this page Flat Rock figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Seneca 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 Flat Rock.
Is zoning published for Flat Rock?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
