One of the most potent predictors of divorce is the age of marriage. According to a 1990 U.S. Census report, couples married before the age of thirty were more likely to get divorced than those married at thirty or older. In fact, this worked in a step-wise fashion. Women married before age twenty had a higher rate of divorce than those married from age twenty to twenty-four, who in turn had a higher divorce rate than those married between ages twenty-five to twenty-nine. Whether a baby was conceived or born before the marriage also contributed to the divorce rate, such that couples who conceived or gave birth after marriage were less likely to get divorced. Other risk factors for divorce include financial instability, distant or acrimonious relationships with the extended family, and lack of positive marital role models.
