This is a small place, and the figures below carry wide margins.
The American Community Survey reaches Cobb Island through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 916 with a margin of error of plus or minus 462, which is 50.4 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.

Charles County, not Cobb Island
Charles County context, not Cobb Island figures
These are Charles County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Cobb Island measurements.
- Establishments in Charles County2,793
- Employment at those establishments, Charles County33,675
- Covered employment, Charles County43,087
- Average annual pay, Charles County$60,436
- Average weekly wage, Charles County$1,162
- Housing units permitted, Charles County1,542
- Of those, single family, Charles County1,026
- County product, 2024, Charles County$8,671,815,000
- County product change over the prior year, Charles County8.2 percent
- Average income of an arriving household, Charles County$66,786
Every figure in this section is published for Charles County as a whole and is not a measurement of Cobb Island. 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.

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

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