New Study Ranks Illinois as #1 in Total Economic Output in the U.S.

Corn farming is one of the largest sectors in American agriculture. The nation’s corn farmers bolster the economy and help build strong communities. There are firms in 524 industry sectors across all 50 states and the District of Columbia with linkages to corn grain farming.

In 2023, Illinois farmers produced 2.27 billion bushels of corn, slightly up from the previous year, with an average yield of 206 bushels per acre. While Illinois ranks number two in corn production, it is number one in total economic output contribution due to corn farming, along with its upstream supply chain and household linkages.

Why is Being #1 in Economic Output So Important?

Being number one in economic output means:

More jobs
A stronger economy
Global influence
Technological advancements
Thriving communities
Better environmental practices

Just like a winning team brings pride and benefits to its supporters, Illinois’s success in corn farming brings significant advantages to the state and its residents.

The study relied on IMPLAN, an economic analysis software, to calculate the direct, indirect, and induced impact of corn farming for grain production on the U.S. economy at the state and national level.

“This report highlights the crucial role America’s corn growers play in our nation’s agricultural and economic value chain,” said NCGA Lead Economist Krista Swanson, who authored the analysis. "The data show that growers remain deeply rooted in rural America, where they serve as pillars of economic growth. They work to foster technological innovation, expand commercial opportunities, advance free trade, build the bioeconomy, and feed a hungry world.”
