McHenry County, not Island Lake
McHenry County context, not Island Lake figures
These are McHenry County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Island Lake measurements.
- Establishments in McHenry County8,140
- Employment at those establishments, McHenry County87,684
- Covered employment, McHenry County96,922
- Average annual pay, McHenry County$55,107
- Average weekly wage, McHenry County$1,060
- Housing units permitted, McHenry County1,565
- Of those, single family, McHenry County887
- County product, 2024, McHenry County$15,982,773,000
- County product change over the prior year, McHenry County4.6 percent
- Average income of an arriving household, McHenry County$80,258
Every figure in this section is published for McHenry County as a whole and is not a measurement of Island Lake. 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.
- 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.

Do SBA loans to Island Lake borrowers get paid back?

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