This is a small place, and the figures below carry wide margins.
The American Community Survey reaches Post Mountain through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 233 with a margin of error of plus or minus 238, which is 102.1 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.

Trinity County, not Post Mountain
Trinity County context, not Post Mountain figures
These are Trinity County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Post Mountain measurements.

Every figure in this section is published for Trinity County as a whole and is not a measurement of Post Mountain. 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 approvals are recorded to a borrower address in this place in either FOIA release.
- 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 owner-occupied home value is published for this place.
- 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.

Are the county figures on this page Post Mountain figures?
No, and they are labelled so.

They appear in one clearly marked section as context and are never presented as measurements of Post Mountain.
Is zoning published for Post Mountain?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
