Description

This map shows the number of acres in rural transportation land in each state for the years 1982, 1987, 1992, and 1997. The bars are proportional to the amount of rural transportation land in the state. National totals for each year are also given. All data values are in hundreds of acres.

Cautions for this Product:
Data are not collected on Federal land. The national bar chart is not proportional to the state bar charts.

Distributor: USDA-NRCS-RIAD
Reliability:
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.
