This is a small place, and the figures below carry wide margins.
The American Community Survey reaches Carbon through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 46 with a margin of error of plus or minus 25, which is 54.3 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.

Adams County, not Carbon
Adams County context, not Carbon figures
These are Adams County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Carbon measurements.
- Establishments in Adams County98
- Employment at those establishments, Adams County1,212
- Covered employment, Adams County1,187
- Average annual pay, Adams County$49,596
- Average weekly wage, Adams County$954
- Housing units permitted, Adams County2
- Of those, single family, Adams County2
- County product, 2024, Adams County$265,904,000
- County product change over the prior year, Adams County-2.3 percent
- Average income of an arriving household, Adams County$37,859
Every figure in this section is published for Adams County as a whole and is not a measurement of Carbon. 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.
- 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 Carbon figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Adams 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 Carbon.
Is zoning published for Carbon?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
