Note, I haven't analyzed this study in detail, and many influential papers in sociology can not be replicated.
"The predictors of divorce, however, remain mysterious. But in a new study published in the American Sociological Review, Harvard sociologist Alexandra Achen Killewald has found that the things that increase the probability of divorce — as they relate to work, at least — have changed over the past couple decades. It turns out that the amount of money that either the husband or wife makes isn’t that important: For contemporary couples, the biggest determinant is whether the husband is working full-time.
The data set is enviably large. She tracked 6,309 married couples between 1968 and 2013, 1,684 of whom divorced or permanently separated during that time. To account for the “quiet revolution,” or the time when women could count on pursuing full-fledged careers, she drew a line between couples married before and after 1975. In the early cohort, wives who did 50 percent of the housework had a 1.5 percent chance of divorce within the next year, while those who did 75 percent of the housework had a 1.1 percent chance. In the later cohort, wives’ paid or unpaid labor had little effect on her chance of divorce, but the husband’s breadwinning mattered a lot. If he was employed full-time, there was a 2.5 percent chance of splitting up in the next year, and if he wasn’t, there was a 3.3 percent chance. These might not seem like gigantic numbers, but they’re measuring year-to-year probabilities rather than the total timeline of a marriage, and for an event that affects the life course as much as divorce does, they’re worth paying attention to."
