Suicides in Minnesota rose 6 percent last year, extending a slow but vexing trend and reaching the highest level since the state began tracking them in the early 1900s.
Minnesota recorded 726 suicides for 2015, up from 686 in the prior year, the Department of Health said Wednesday.
Last year's increase largely reflected a rise in suicides among men, particularly white men ages 25 to 34.
"Working-age white males continue to be an area where we need to do more work and we need to do better work," said Melissa Heinen, a suicide epidemiologist for the Health Department.
Suicides declined among Minnesotans under 25, and state prevention campaigns at least stabilized suicide death rates among middle-aged men and American Indian youths, Heinen said.
Wednesday's data release is part of an enhanced state suicide epidemiology program, which is receiving earlier access to death records involving suicides with the aim of providing real-time solutions.
"We actually can look to see if there is a contagion or a cluster" of suicides in a particular region or demographic group, Heinen said.
Firearms continue to be the most common means of suicide, and are more commonly used by men.
