China Dominates Global Sweet Potato Production, Contributing Over Half of World Output

23 October 2025, Beijing: Sweet potatoes and yams are often mistaken for one another, yet they are entirely distinct crops. Yams, native to Africa and Asia, have a rough, bark-like exterior, while sweet potatoes—originally from Central and South America—feature smoother skin and a naturally sweet flavor.

In recent decades, Asia has emerged as the global hub of sweet potato production. Data compiled from Statista and other global agricultural sources indicate that China alone produces over 50 million tons of sweet potatoes annually, accounting for around 55% of global output. Much of this production is consumed domestically, either as a staple food or processed for use in starch, alcohol, and animal feed industries.

Several Chinese provinces specialize in sweet potato cultivation, with the crop deeply integrated into local rural economies. Small-scale family farms, cooperatives, and large agri-enterprises contribute to both domestic supply and exports, supported by modern logistics and e-commerce channels that have expanded market access in recent years.

While China leads in global output, the United States remains one of the top producers, primarily serving domestic demand. Statista data suggest that U.S. production exceeds one billion tons annually, far surpassing import volumes. The majority of American production is concentrated in North Carolina, which accounts for over 60% of the national total, followed by California and Mississippi.

Commonly cultivated U.S. varieties include Jewel, Beauregard, Red Garnet, and Japanese Murasaki. The orange-fleshed types are typically used in purees, bakery products, and baby food, while firmer-textured varieties like Murasaki are favored for fried and processed foods.

Globally, sweet potatoes are valued for their adaptability, nutritional content, and contribution to food security. Uniform size, smooth skin, and consistent color remain the key quality indicators for both retail and processing markets. With increasing attention on sustainable, nutrient-rich crops, the sweet potato continues to play a vital role in agricultural economies across continents.
