This is a small place, and the figures below carry wide margins.
The American Community Survey reaches Cardiff through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 125 with a margin of error of plus or minus 115, which is 92.0 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.

Jefferson County, not Cardiff
Jefferson County context, not Cardiff figures
These are Jefferson County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Cardiff measurements.
- Establishments in Jefferson County16,989
- Employment at those establishments, Jefferson County341,042
- Covered employment, Jefferson County367,081
- Average annual pay, Jefferson County$71,562
- Average weekly wage, Jefferson County$1,376
- Housing units permitted, Jefferson County2,117
- Of those, single family, Jefferson County1,536
- County product, 2024, Jefferson County$65,539,202,000
- County product change over the prior year, Jefferson County4.3 percent
- Average income of an arriving household, Jefferson County$73,144
Every figure in this section is published for Jefferson County as a whole and is not a measurement of Cardiff. 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.
- 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.
