The United States, with 25 percent of world peanut exports and 10 percent of world peanut production, is the leading peanut exporter and the third largest producer; only India and China produce more. U.S. production has nearly doubled since the early fifties, chiefly because of increases in yields. Most peanut consumption in the United States is for food, especially peanut butter, whereas most foreign countries use peanuts for oil. Canada is the leading importer of U.S. peanuts.
