Ninety-one percent of U.S. farms are classified as small—gross cash farm income (GCFI) of less than $250,000. About 60 percent of these small farms are very small, generating GCFI of less than $10,000. These very small non-commercial farms, in some respects, exist independently of the farm economy because their operators rely heavily on off-farm income. The remaining small farms—small commercial farms—account for most small-farm production. Overall farm production, however, continues to shift to larger operations, while the number of small commercial farms and their share of sales maintain a long-term decline. The shift to larger farms will continue to be gradual, because some small commercial farms are profitable and others are willing to accept losses.
