Suicide rates rose steadily in nearly every state from 1999 to 2016, often by as much as 30 percent, the Centers for Disease Control and Prevention reported on Thursday. In 2016, there were more than twice as many suicides as homicides in the United States.

The figures come two days after the death of celebrity designer Kate Spade, which has sparked a national conversation about suicide.

She had struggled with depression and anxiety for years, according to a statement released by her husband, Andrew Spade. “She was actively seeking help and working closely with her doctors to treat her disease,” he wrote.

C.D.C. officials, however, said that the national increase in suicide rates cannot be linked to a particular mental health diagnosis.
