Pennington County, not Keystone

Pennington County context, not Keystone figures

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

  • Establishments in Pennington County4,137
  • Employment at those establishments, Pennington County52,402
  • Covered employment, Pennington County62,114
  • Average annual pay, Pennington County$57,286
  • Average weekly wage, Pennington County$1,102
  • Housing units permitted, Pennington County1,183
  • Of those, single family, Pennington County447
  • County product, 2024, Pennington County$8,688,330,000
  • County product change over the prior year, Pennington County5.6 percent
  • Average income of an arriving household, Pennington County$79,958

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

No, and they are labelled so.

Is zoning published for Keystone?

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