Older-male age gap relationships are more fertile than age-matched relationships.

The effect peaks at 0.25 more children per couple when the husband is 7 years older.

Conversely, couples have 0.75 fewer children when wives are 7 years older.

The effect sizes may seem small, but every couple having 0.25 more children would compound and result in massive population-scale changes in only a few generations.

Unfortunately, older-male age gap relationships have declined since the mid-to-late 19th century, and for this you can thank feminism and anti age gap hysteria.
