U.S. farmers plant approximately 125,000 acres of onions each year and produce about 6.98 billion pounds a year. This includes organic production, but excludes bulb onions for dehydration. In Idaho farmers plant 22,800 acres in onions.
The U.S. has 4.5% of the world's population, accounts for 1.6% of the world onion acreage, and produces about 4% of the world's annual supply. The U.S. dry bulb onion crop value exceeds $1 billion at farmgate and generates $5-7 billion dollars at consumer purchase level.
The top three onion producing areas are California, Idaho-Eastern Oregon, and Washington.
