Why did so many US farms disappear around the 1970s and 1980s?
The US had more than five million farms in 1950. By 1982, that number had fallen to about 2.2 million. The decline had already been underway for decades, but the number of farms continued falling through the 1970s, while the farm crisis of the 1980s brought another major disruption to rural America.
What made it possible for so many farms to remain viable in earlier decades, and what changed by the 1970s and 1980s?
