Charleston County, not James Island
Charleston County context, not James Island figures
These are Charleston County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as James Island measurements.
- Establishments in Charleston County15,801
- Employment at those establishments, Charleston County226,330
- Covered employment, Charleston County278,476
- Average annual pay, Charleston County$68,271
- Average weekly wage, Charleston County$1,313
- Housing units permitted, Charleston County4,153
- Of those, single family, Charleston County3,052

- County product change over the prior year, Charleston County7.9 percent
- Average income of an arriving household, Charleston County$117,050
Every figure in this section is published for Charleston County as a whole and is not a measurement of James 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.
- 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.
