In a week when two celebrities, first the designer Kate Spade and then the chef and television host Anthony Bourdain, took their own lives, new federal data was released showing that suicide rates have been increasing for years in almost every state and across demographic lines.

The escalating crisis has affected nearly every group and place, but the study from the Centers for Disease Control and Prevention showed that some parts of the country have been hit especially hard. Here’s a closer look at the study and the stories behind some of the data.

Veteran deaths help account for Montana’s high rate.

Montana has the country’s highest suicide rate, and suicides by military veterans are a significant contributor. A state study found that veterans account for more than 20 percent of Montana’s suicides and that veterans have a suicide rate more than twice that of nonveterans.

“All the issues that we have in Montana are magnified in our veteran population,” said Karl Rosston, the state’s suicide prevention coordinator. Mr. Rosston said rural isolation, easy access to guns and a lack of mental health services likely contributed to Montana’s suicide rate, which has been among the country’s highest for decades.
