Top Pig-Producing States in the USA: Regional Powerhouses of American Pork
Introduction
After 20+ years running a 5,000-head operation in North Carolina, I’ve seen firsthand how geography shapes the American pork industry. Understanding commercial pig farming by state is essential for anyone evaluating market opportunities, supply chains, or regional competitiveness.
According to the USDA National Agricultural Statistics Service (NASS) December 2024 report, the United States has approximately 74.1 million hogs and pigs, with over 60% concentrated in just five states.
This regional concentration is not coincidental; it demonstrates the effective interplay of climate, feed availability, processing infrastructure, and agricultural knowledge.
Case Study – The Iowa Advantage: Iowa’s combination of 12+ million acres of corn production, world-class land-grant universities, and established infrastructure makes it the undisputed leader.
The Iowa Pork Producers Association says that Iowa has more pigs than the next five states put together.
This regional analysis connects to pig farming economics because location directly impacts feed costs, transportation, and market access. Understanding these dynamics helps farmers make smarter business decisions.
