"The United States has a total land area of nearly 2.3 billion acres. Major uses in 2002 were forest-use land, 651 million acres (28.8 percent); grassland pasture and range land, 587 million acres (25.9 percent); cropland, 442 million acres (19.5 percent); special uses (primarily parks and wildlife areas), 297 million acres (13.1 percent); miscellaneous other uses, 228 million acres (10.1 percent); and urban land, 60 million acres (2.6 percent)." from... http://www.ers.usda.gov/Publications/EIB...

Much of the research has gone into urban sprawl.  Population centers keep growing geographically without reusing underused land in the center of cities.

There is much data at http://www.sprawlcity.org/
