Sioux County, not Alton
Sioux County context, not Alton figures
These are Sioux County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Alton measurements.
- Establishments in Sioux County1,345
- Employment at those establishments, Sioux County20,910
- Covered employment, Sioux County22,957
- Average annual pay, Sioux County$55,762
- Average weekly wage, Sioux County$1,072
- Housing units permitted, Sioux County251
- Of those, single family, Sioux County146
- County product, 2024, Sioux County$3,920,054,000
- County product change over the prior year, Sioux County19.2 percent
- Average income of an arriving household, Sioux County$56,406
Every figure in this section is published for Sioux County as a whole and is not a measurement of Alton. 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.
