Percent of Land in Federal Ownership, 1997

Thumbnail version of the map. Select for a popup of the full sized map.


The shaded polygon map shows the percentage of land owned by the Federal government. The 95% or more category is determined by a combination of actual boundaries of Federal land from USGS and data from the 1997 National Resources Inventory (NRI). The 50% to 95%, 5% to 50%, and less than 5% are based on 1997 NRI data aggregated by 8-digit hydrologic unit. 402,138,100 acres or 21% of the total land area is Federally owned (excluding Alaska).

Cautions for this Product:
This map may not be used to determine site- specific information. No NRI data are available for Alaska.

NRI sample data are generally reliable at the 95% confidence interval for state and certain broad substate area analyses. Generally, analyses that aggregate data points by smaller geographic areas and/or more specific criteria result in fewer data points for each aggregation and therefore less reliable estimates. NRI maps reflect national patterns rather than site- specific information.
