Market and Productivity Value Data-collected at the ISD (independent school district) level
Market value-the value of the land
Production value-the value of the agricultural commodities produced by the land
- Comptroller data were statistically adjusted to remove outliers.
- Values for ISDs that no longer exist due to a consolidation were retroactively assigned to the new ISD.
- County level land use and land value metrics are made up of an aggregation of all independent school districts whose center points fall within the selected county boundary. Because of this, it is likely that total land use area will exceed the actual are of the county itself.
