Could Raising The Minimum Wage Lower Suicide Rates?

More than 47,000 American died by suicide in 2017 alone. Along with other so-called "deaths of despair" -- drug overdoses and alcoholism -- suicide is slowly growing into a public health crisis. But a new study published last week revealed that raising the minimum wage could lower the suicide rate, particularly among adults aged 18 to 64 with a high school education or less -- a group more likely than others to be affected by wage changes.

Researchers estimated that a $1 increase in the minimum wage corresponded with a 3.5% decrease in the suicide rate for those with a high school education or less, with the effect being most pronounced during times of high unemployment.

Is there a causal connection between higher wages and lower suicide rates? What about suicide rates among those with some college education?
