When the Department of Agriculture was founded in 1862 by an act of Congress and signed into law by President Lincoln, roughly half the population of the United States lived on farms and followed an agrarian lifestyle. Today, according to the USDA website, only about 2% of the population live on farms though our society's dependence on food cultivated by those farms hasn't changed.
