"The proportion of childless men (at age 40 years) has increased rapidly for Norwegian male cohorts from 1940 to 1970 (from 15 to 25 per cent). For women, it has only increased marginally (from 10 to 13 per cent)." Personality Traits Increasingly Important for Male Fertility: Evidence from Norway

Our findings suggest that this could be partly explained by the increasing importance of personality characteristics for men’s probability of becoming fathers.

" conscientiousness decreases female fertility, openness decreases male fertility "

Imagine coming to this conclusion unironically.

This is confusing to me. What’s accounting for the 13% difference between male and female fertility? Are 13% of women in Norway actually single mothers? That seems way too high. Is this instead a case of divorced men claiming they don’t have children and divorced women claiming they do?

Actually, it may have something to do with male and female age differences in marriage, no? For many couples, the male is older than a female. So perhaps instead you should be looking at fertility at age 60. Because if the average 39yo woman is knocked up by a 42yo man that will have a 2-8% difference in fertility by age 40 I think. But I still think self-reporting divorcees matters.

Don't forget to look at the change in sperm count. Norwegian sperm quality is so low now large groups can no longer become fathers without a doctor with a Petri dish.
