U.S. Suicide Rates Are the Highest They've Been Since World War II

U.S. suicide rates are at their highest since World War II, according to federal data—and the opioid crisis, widespread social media use and high rates of stress may be among the myriad contributing factors.

In 2017, 14 out of every 100,000 Americans died by suicide, according to a new analysis released by the Centers for Disease Control and Prevention’s National Center for Health Statistics. That’s a 33% increase since 1999, and the highest age-adjusted suicide rate recorded in the U.S. since 1942. (Rates were even higher during the Great Depression, hitting a century peak of 21.9 in 1932.)

“I don’t think there’s a one-size-fits all reason” since there’s almost never a single cause of suicide, says Jill Harkavy-Friedman, vice president of research at the American Foundation for Suicide Prevention, a nonprofit that supports suicide prevention research, education and policy. “I don’t think there’s something you can pinpoint, but I do think a period of increased stress and a lack of a sense of security may be contributing.”

It’s even more difficult to assign causes to the uptick, Harkavy-Friedman says, because it’s happening across diverse demographic groups. Men have historically died by suicide more frequently than women, and that’s still true: As of 2017, the male suicide rate was more than three times higher than the female rate. But female suicide rates are rising more quickly—by 53% since 1999, compared to 26% for men—and the gap is narrowing. For both genders, suicide rates are highest among American Indians and Alaska natives, compared to other ethnicities, and when the data are broken down by age group, the most suicide deaths are reported among people ages 45 to 64—but nearly every ethnic and age group saw an increase of some size from 1999 to 2017.

In Spain, prisoners’ brains are being electrically stimulated in the name of science

A team of scientists in Spain is getting ready to experiment on prisoners. If the scientists get the necessary approvals, they plan to start a study this month that involves placing electrodes on inmates’ foreheads and sending a current into their brains. The electricity will target the prefrontal cortex, a brain region that plays a role in decision-making and social behavior. The idea is that stimulating more activity in that region may make the prisoners less aggressive.

This technique — transcranial direct current stimulation, or tDCS — is a form of neurointervention, meaning it acts directly on the brain. Using neurointerventions in the criminal justice system is highly controversial. In recent years, scientists and philosophers have been debating under what conditions (if any) it might be ethical.

The Spanish team is the first to use tDCS on prisoners. They’ve already done it in a pilot study, publishing their findings in Neuroscience in January, and they were all set to implement a follow-up study involving at least 12 convicted murderers and other inmates this month. On Wednesday, New Scientist broke news of the upcoming experiment, noting that it had approval from the Spanish government, prison officials, and a university ethics committee. The next day, the Interior Ministry changed course and put the study on hold.

Andrés Molero-Chamizo, a psychologist at the University of Huelva and the lead researcher behind the study, told me he’s trying to find out what led to the government’s unexpected decision. He said it makes sense to run such an experiment on inmates because “prisoners have a high level of aggressiveness.”
