The USDA undercounted corn acreage by 4.5 million acres last year, raising questions about the reliability of government agricultural data that farmers and traders depend on for decisions worth billions of dollars.
The Agriculture Department blamed low survey response rates rather than staffing shortages for the miss. Fewer farmers completed USDA questionnaires, leaving the agency with incomplete data to estimate total planted acreage.
This matters because the USDA's crop reports move commodity prices and influence planting decisions across the country. Traders use these figures to assess supply and set prices for corn futures. Farmers rely on USDA estimates to plan next season's operations.
The undercount signals a broader problem. If response rates continue falling, future estimates could miss the mark by even larger margins. The USDA did not specify what caused lower participation or whether it plans to boost response rates through improved outreach or incentives.
The agency said it will review its methodology going forward. Fixing this problem requires either increasing survey participation or developing new ways to count crops reliably. Without accurate baseline data, the entire agricultural market operates with less certainty.
