A new USDA report shows 99 percent of U.S. farmers were "family farms" in 2015.
A family farm is classified as a farm where the principal operator and his or her relatives own the majority of the business.
Breaking it down by size, the report shows small family farms, those less than $350,000 in annual gross cash farm income accounted for roughly 90 percent of U.S. farms, half of all farmland, and a quarter of the value of production.
Midsize and large-scale family farms, made up 9 percent of U.S. farms, but contributed most of the value of production.
However, small family farms did produce a relatively large share of two commodities in 2015: 57 percent of all poultry and eggs and 52 percent of the nation's hay crop.
