But whatever the direct effect of education on never-married men, the primary cause of the rise in sexlessness is simply the increasing delay of marriage. The delay in marriage has numerous causes, of course, but probably the most powerful driver of marital timing also relates to education. Men and women are much less likely to get married while attending school, and across times and countries, an increase in the years of schooling is associated with later age of marriage, though more-educated people do tend to get married eventually. Thus, as more and more schooling becomes necessary for a good middle-class job, marriage gets pushed later and later, leaving more young people (men and women!) companionless and lonely.

The rise of young male sexlessness isn’t about Chads and Stacies; it isn’t primarily about Tinder or Bumble; it’s not mostly about attitudinal shifts in what women want from relationships; and it’s not mainly about some new war between the sexes. It’s mostly about people spending more years in school and spending more years living at home. But that’s not actually a story about some change in sexual politics; instead, it’s a story about the modern knowledge economy, and to some extent exorbitant housing costs. As such, it’s no surprise that rising sexlessness is being observed in many countries. This, in turn, suggests that finding a solution to help young people pair up may not be as easy.
