| Farmland and buildings, an acre, 2022 | $2,513 |
|---|---|
| The same, 2017 | $1,980 +27% |
| Farms counted, 2022 | 258 (256 in 2017) |
| Average farm | 1,721 acres |
| Share of the county that is farmland | 97.9% |
| Median value of an owner-occupied home | $136,600 ± $25,800 |
The farm figure is land and buildings together, averaged over every farm in the county, from the largest ranch to the smallest holding. It is for comparing one county with another, not a price for any parcel: a few acres with road frontage usually costs more an acre than the average, not less.
