Foreigners owned 7.8 million acres of U.S. agricultural land as of December 31, 1980. This is 0.6 percent of all privately held agricultural land and 0.35 percent of all land in the United States. This share is too small to measure the impact on agriculture at the national level. However, some communities in areas of heaviest concentration could be adversely affected. These findings are based on an analysis of reports submitted in compliance with the Agricultural Foreign Investment Disclosure Act of 1978.
