This is a small place, and the figures below carry wide margins.
The American Community Survey reaches Grenville through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 53 with a margin of error of plus or minus 41, which is 77.4 percent of the estimate itself. Every figure whose margin reaches 20 percent is printed with that margin beside it, so you can see the width of each one rather than having to assume it.
Nothing has been removed or adjusted. These are the published federal estimates, shown with the uncertainty the Census publishes alongside them.

Day County, not Grenville
Day County context, not Grenville figures
These are Day County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Grenville measurements.
- Establishments in Day County226
- Employment at those establishments, Day County1,372
- Covered employment, Day County1,955
- Average annual pay, Day County$44,886
- Average weekly wage, Day County$863
- Housing units permitted, Day County34
- Of those, single family, Day County34
- County product, 2024, Day County$380,745,000
- County product change over the prior year, Day County-8.2 percent
- Average income of an arriving household, Day County$67,832
Every figure in this section is published for Day County as a whole and is not a measurement of Grenville. 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.
