U.S. production of sweet potatoes has increased substantially in recent years, achieving a new record-high of 3.1 billion pounds in 2015—a 4.8- percent increase over 2014’s 3.0 billion pounds. The largest producer of sweet potatoes in the United States is North Carolina which harvested 1.6 billion pounds in 2015 and has been responsible for most of the gains in recent years. California, Mississippi, and Louisiana are also notable sweet potato-producing States.
In 2014 and 2015, sweet potato production rose by an average of about 6 percent per year, bolstered by growth in exports and domestic demand. Between 2000 and 2015, domestic consumption of sweet potatoes grew considerably with per capita availability rising from 4.2 pounds to 7.5 pounds.
The marked rise in domestic demand has been encouraged by promotion of the tuber’s health benefits. Sweet potatoes are a good source of fiber and vitamin C, and they are an especially rich source of vitamin A.
