I married The Husband when I had just turned 21, and have been amazed all these years at my good fortune.

Back then a lot of people wondered if that was a good decision. The answer, decades later, is yes.

Sociologist Mark Regnerus writes in the Washington Post today, Say Yes. What Are You Waiting For?

Of course, there’s at least one good statistical reason to urge people to wait on the wedding. Getting married at a young age remains the No. 1 predictor of divorce. So why on earth would I want to promote such a disastrous idea? For three good reasons:

First, what is considered “early marriage” by social scientists is commonly misunderstood by the public. The best evaluations of early marriage — conducted by researchers at the University of Texas and Penn State University — note that the age-divorce link is most prominent among teenagers (those who marry before age 20). Marriages that begin at age 20, 21 or 22 are not nearly so likely to end in divorce as many presume.

Second, good social science pays attention to gender differences. Most young women are mature enough to handle marriage. According to data from the government’s National Survey of Family Growth, women who marry at 18 have a better shot at making a marriage work than men who marry at 21. There is wisdom in having an age gap between spouses. For women, age is (unfortunately) a debit, decreasing fertility. For men, age can be a credit, increasing their access to resources and improving their maturity, thus making them more attractive to women. We may all dislike this scenario, but we can’t will it away.

Third, the age at which a person marries never actually causes a divorce. Rather, a young age at marriage can be an indicator of an underlying immaturity and impatience with marital challenges — the kind that many of us eventually figure out how to avoid or to solve without parting. Unfortunately, well-educated people resist this, convinced that there actually is a recipe for guaranteed marital success that goes something like this: Add a postgraduate education to a college degree, toss in a visible amount of career success and a healthy helping of wealth, let simmer in a pan of sexual variety for several years, allow to cool and settle, then serve. Presto: a marriage with math on its side.

Regnerus hits the bulls-eye next:

Too bad real life isn’t like that. Marriage actually works best as a formative institution, not an institution you enter once you think you’re fully formed. We learn marriage, just as we learn language, and to the teachable, some lessons just come easier earlier in life. “Cursed be the social wants that sin against the strength of youth,” added Tennyson to his lines about springtime and love.
