New CDC figures documenting the growing rate of suicide may not reflect the full scope of the problem, said Mark S. Kaplan, professor of social welfare at UCLA Luskin. Many suicides are actually classified as ”accidental deaths,” Kaplan, a noted suicide prevention researcher, told WebMD. “Some are classified as unintentional self-injury when, in fact, if you take a closer look, they look more like suicide,” he said. “The true incidence of suicide is unknown.” Kaplan said the Great Recession from 2007 to 2009 contributed to what he terms ”deaths of despair” by suicide. Some people, he said, never recovered economically.
