Spread of coitus interruptus and other such techniques in France in the 1700s? French military strategists were concerned about how Germans were more fertile a long time ago.

French fertility transition began among aristocrats (1600-1800) and long before anywhere else. (France is to the demographic transition what England is to the industrial revolution.) Maybe due to desire not to split lands among many heirs.

I thought that right before the revolution France's fertility was at a record high and it collapsed shortly thereafter

I read an interesting paper once about France's fertility decline post revolution where they mentioned that it only took about 10-20% of women limiting their total number of children to about 3 to effect the fertility decline that France experienced

nobody really knows the cause, but it is remarkable that it happened in what was still a peasant country, with low literacy, before industry and large urbanization had spread

As the paper hbd links to suggests, an attitudinal shift in a minority of women is enough to do the trick and seismic cultural event like the Revolution is probably what triggered it

in Rouen aristocratic fertility was already at modern levels (2.7) before the revolution, and other classes were falling too.pic.twitter.com/tOfLdr95As

This paper suggests reason is upper class women going childless to participate more actively in socialite society. The high fertility of lower classes is surprising though, given that in most other places pre-transition it was higher among higher classes

didn't they have servants to allow them to both have children and socialize? (Thanks for bringing this paper to attention -- a couple years ago now!)

yes, the authors very much come away from the paper with as many questions as they have answers

they consider and reject that. In fact, while society was fairly secular in cities, even then, the workers were more secular than the aristos!
