Millennials Are Causing the U.S. Divorce Rate to Plummet

Americans under the age of 45 have found a novel way to rebel against their elders: They’re staying married.

New data show younger couples are approaching relationships very differently from baby boomers, who married young, divorced, remarried and so on. Generation X and especially millennials are being pickier about who they marry, tying the knot at older ages when education, careers and finances are on track. The result is a U.S. divorce rate that dropped 18 percent from 2008 to 2016, according to an analysis by University of Maryland sociology professor Philip Cohen.

Demographers already knew the divorce rate was falling, even if the average American didn’t. Their question, however, was why? And what do current trends mean for the marital prospects of today’s newlyweds?

One theory is that divorce rates are falling largely because of other demographic changes—especially an aging population.

Many poorer and less educated Americans are opting not to get married at all. They’re living together, and often raising kids together, but deciding not to tie the knot. And studies have shown these cohabiting relationships are less stable than they used to be.

Fewer divorces, therefore, aren’t only bad news for matrimonial lawyers but a sign of America’s widening chasm of inequality. Marriage is becoming a more durable, but far more exclusive, institution.
