The Role of Marriage in the Suicide Crisis
America is in the middle of a suicide crisis. Since the turn of the millennium, the suicide rate has risen 35%, increasing year-on-year. In 2018, there were nearly 50,000 suicides, the highest per capita rate since the second World War.
As I've written at the Washington Free Beacon, this unprecedented spike resists easy explanation. Popular theories—the widespread availability of firearms, the rise of social media and the internet, and spiking "despair"—at best account for a fraction of the increase. As such, assuming that the crisis is multicausal, it is worth investigating the roll that changing social institutions play in mediating suicide risk.
Personal relationships, and marriage in particular, bear substantially on self-inflicted mortality risk, including suicide. As University of Maryland sociologist Philip N. Cohen noted in a working paper last year, the increase in overall mortality rates among white Americans—so-called "deaths of despair" attributed to "self-inflicted" causes like drug overdose, suicide, and alcohol abuse—is "limited almost exclusively to those who are not married, for men and women." Research from the National Longitudinal Mortality Study (NLMS) finds that divorced people, in particular, were twice as likely to commit suicide compared to married people.
Those findings comport with mortality data from the CDC's annual Multiple Cause of Death Files, adjusted for population estimates for different married groups based on the Current Population Survey's Annual Social and Economic Supplement.
The effect apparent from the population-level data is even more pronounced than that in the NLMS data. The suicide rate among divorced adults is more than three times that of married adults, while the suicide rate among singles is 1.5 to 2 times the rate among those who are married. In other words, marriage is a protective factor for suicide risk.
There are multiple stories that one could tell about this finding. Those who are more likely to marry may also be less likely to commit suicide, for reasons of personality, environment, or both. Socioeconomic status, in particular, mediates the relationship between marriage and suicide risk: increasing white mortality rates are driven by those at the bottom of the education distribution, who are also increasingly less likely to be married compared to their well-educated peers.
It is not implausible, however, that there is also some causal relationship between marriage and lowered suicide risk. Married people are on average happier. They also, definitionally, have at least one person to whom they are robustly socially linked—meaning they are less likely to be lonely, among other positive outcomes. Divorce, by contrast, is linked to depression in at least some people.
In assessing the relationship between marriage and the suicide spike, it is worth examining how the marital composition of the population has shifted over the past 20 years. In 1999, 58.6% of the over-18 population was married; in 2019, that figure was 54 percent. The single share of the population, meanwhile, rose from 24.4% to 29.6%, while divorced and widowed shares remained constant. In other words, America has grown slightly less married, slightly more single, selecting overall into a more suicide-prone category.
