McLean County, not Twin Grove

McLean County context, not Twin Grove figures

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

  • Establishments in McLean County3,481
  • Employment at those establishments, McLean County75,617
  • Covered employment, McLean County88,945
  • Average annual pay, McLean County$66,183
  • Average weekly wage, McLean County$1,273
  • Housing units permitted, McLean County243
  • Of those, single family, McLean County166
  • County product, 2024, McLean County$16,910,293,000
  • County product change over the prior year, McLean County5.7 percent
  • Average income of an arriving household, McLean County$67,848

Every figure in this section is published for McLean County as a whole and is not a measurement of Twin Grove. 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.
