Custer County, not Mackay
Custer County context, not Mackay figures
These are Custer County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Mackay measurements.
- Establishments in Custer County192
- Employment at those establishments, Custer County862
- Covered employment, Custer County1,539
- Average annual pay, Custer County$45,656
- Average weekly wage, Custer County$878
- Housing units permitted, Custer County49
- Of those, single family, Custer County49
- County product, 2024, Custer County$257,340,000
- County product change over the prior year, Custer County3.6 percent
- Average income of an arriving household, Custer County$64,298
Every figure in this section is published for Custer County as a whole and is not a measurement of Mackay. 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.
- 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.
