Kane County, not Big Rock
Kane County context, not Big Rock figures
These are Kane County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Big Rock measurements.

- Employment at those establishments, Kane County194,921
- Covered employment, Kane County213,795
- Average annual pay, Kane County$62,791
- Average weekly wage, Kane County$1,208
- Housing units permitted, Kane County2,132
- Of those, single family, Kane County1,741

- County product change over the prior year, Kane County4.5 percent
- Average income of an arriving household, Kane County$85,505
Every figure in this section is published for Kane County as a whole and is not a measurement of Big Rock. 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 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.
