Winneshiek County, not Castalia

Winneshiek County context, not Castalia figures

These are Winneshiek County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Castalia measurements.

  • Establishments in Winneshiek County604
  • Employment at those establishments, Winneshiek County9,065
  • Covered employment, Winneshiek County10,479
  • Average annual pay, Winneshiek County$51,439
  • Average weekly wage, Winneshiek County$989
  • Housing units permitted, Winneshiek County47
  • Of those, single family, Winneshiek County35
  • County product, 2024, Winneshiek County$1,353,749,000
  • County product change over the prior year, Winneshiek County3.0 percent
  • Average income of an arriving household, Winneshiek County$56,802

Every figure in this section is published for Winneshiek County as a whole and is not a measurement of Castalia. 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 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.

Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
