Those numbers can be quite skewed considering their definition of a “farm” is one that generates as little as $1000 in revenue per year, so anyone with a few chickens in their suburban backyard that sells eggs to their coworkers would fall under this definition. They even outline that 80% of these small family farmers have full-time jobs outside of farming. They also claim giant companies are “family owned” simply because a few family members control a majority stake. One could call Walmart or News Corp “family owned businesses” using this same definition and claim Walmart is a tiny portion of the retail space because there are 500k individuals selling keychains on Etsy versus their single company.

By your link, 90% of farms produce 21% of producs. So yeah, most farms are owned by corpos, if we apply the meaning correctly
