From 2000 to 2012, the overall rates of suicide for people aged 16 and older rose 21 percent, the study found. That works out to an approximate increase from 13 to 16 suicides per every 100,000 people in the United States. But among farmers, fishers and foresters, the suicide rate was dramatically higher — at 85 suicides per 100,000 people. For males in those jobs, the rate was even greater. Their suicide rate was 90.5 suicides per 100,000, according to the report.
