After peaking at 6.8 million farms in 1935, the number of U.S. farms and ranches fell sharply through the early 1970s. Rapidly falling farm numbers in the mid-20th century reflect the growing productivity of agriculture and increased nonfarm employment opportunities.
Since then, the number of U.S. farms has continued to decline, but much more slowly. In 2021, there were 2.01 million U.S. farms, down from 2.20 million in 2007. With 895 million acres of farmland nationwide in 2021, the average farm size was 445 acres, only slightly greater than the 440 acres recorded in the early 1970s.
