Share of land used for agricultural purposes has decreased 11 percentage points since 1949
The U.S. land area totals just under 2.3 billion acres. Land used in agriculture has become less common over time, declining from 63 percent in 1949 to 52 percent in 2012 (the latest data available). Gradual declines have occurred in cropland, while grazed forestland has decreased more rapidly. In 2012, 392 million acres of agricultural land were in cropland (18 percent less than in 1949), 655 million acres were in pasture and range (4 percent more), 130 million acres were in grazed forestland (59 percent less), and 8 million acres were in farmsteads and farm roads (45 percent less). In contrast, land used for rural parks and wilderness (included in nonagricultural special uses) has increased by 226 million acres since 1949, contributing to the relative growth in nonagricultural land use over time. Urban land, which represents a relatively small share of the U.S. land base, has nearly tripled in area since 1949 to accommodate economic and population growth.
