| Farmland and buildings, an acre, 2022 | $3,630 |
|---|---|
| The same, 2017 | $3,205 +13% |
| Farms counted, 2022 | 378 (360 in 2017) |

The farm figure is land and buildings together, averaged over every farm in the parish, from the largest ranch to the smallest holding. It is for comparing one parish with another, not a price for any parcel: a few acres with road frontage usually costs more an acre than the average, not less.
