My last series of posts argued that states should lower the voting age, since by mid-adolescence, teens have the cognitive-processing and reasoning capacities required for voting competence. But that is not to say that teens have attained adult-like capacities across all domains. To the contrary, context matters. And one context in which teens lack competence is marriage.
Through a single statutory adjustment — raising to 21 the age at which individuals may marry — legislators could reduce the percentage of marriages ending in divorce, improve women’s mental and physical health, and elevate women’s and children’s socioeconomic status.
More than 1 in 10 U.S. women surveyed between 2001 and 2002 had married before age 18, with 9.4 million having married at age 16 or younger. In 2010, some 520,000 U.S. teens were married, divorced, or widowed. In an article published last month, The Age of Marital Capacity: Reconsidering Civil Recognition of Adolescent Marriage, I describe more fully the social costs of early marriage and argue for an end to the practice.
The High Costs of Early Marriage
For decades, age at marriage has been the most consistent and unequivocal predictor of marital failure. Of marriages entered at age 25 or later, fewer than 30% end in divorce. Of marriages entered before age 18, on the other hand, nearly 70% end in divorce. The earliest marriers, those adolescents who enter marriage in their mid-teens, experience marital failure rates closer to a sobering 80%. Not until age 22 does marital stability improve significantly and do marriage dissolution rates begin to level off.
The costs of child marriages (entered before age 18) and early marriages more generally (entered at age 21 or younger) extend beyond their dissolution. Early marriers are more likely than those who delay or avoid marriage to discontinue their formal educations prematurely, earn low wages, and live in poverty. Women who marry early develop more mental and physical health problems than those who marry later. And following divorce, mothers (and their children) tend to suffer greater economic deprivation and instability than do their never-married counterparts. (See here, pp. 1799-1806)
Neither attaining age 18 (the near-universal age of presumptive marital capacity) nor obtaining the consent of parents and/or judges (generally required for those individuals seeking to marry before age 18) has an observable effect on marital stability. Only delay and factors integrally associated with it — such as more years of education — reliably increase marital stability.
Causes of Early Marriage Instability
Why are marriages entered at earlier ages so unstable? And what can be done about it? The answer to the first question is complicated; the answer to the second question is not.
