But this is only true up to a point, according to a new analysis of the data: The divorce risk does indeed decline as individuals marry later, but this trend stops in the early 30s. Those who marry in their mid-30s or later are now more likely to divorce than those who marry in their late 20s, says Nicholas H. Wolfinger, a University of Utah psychologist, in a writeup of his new research for the Institute for Family Studies. “My data analysis shows that prior to age 32 or so, each additional year of age at marriage reduces the odds of divorce by 11 percent," Wolfinger writes. "However, after that, the odds of divorce increase by 5 percent per year.”
