Farmers, fishermen, and forestry workers, who are lumped together by government statisticians, have the highest suicide rate of any occupational cluster: 84.5 self-inflicted deaths per 100,000 workers, according to a Centers for Disease Control and Prevention analysis—that would have amounted to almost 900 suicides in 2016. (The CDC does not break out data for farmers specifically.) In general, farmers—at the whims of large agribusinesses, supply and demand, and the weather—always face some degree of uncertainty, with some worries exacerbated by President Donald Trump’s brewing trade war with China. Members of a coalition of agricultural interests, including the National Farmers Union, co-signed a letter in April asking Congress to provide funding for helplines and mental health support groups for agricultural workers. But in dairy circles, the stress is coming to a head as a result of long-standing policies that have nothing to do with Trump.Dairy farmers in the United States are paid by the hundredweight—that’s 100 pounds of milk, about 12 gallons. Milk prices, after peaking in 2014, have plummeted to roughly $15 per hundredweight, forcing many dairy farmers to operate in the red.
