Where I live, most men have some degree of jaw recession, while women tend to have stronger jawlines, even if not perfect. Is it only where I live, or have you noticed that too?
This one of those local things that makes possible to distinguish different ethnicities. Humans propagate physical traits genetically, therefore if a group of people has similar origins they will have some facial features in common as well.
Could be this, if you live in society with high alcoholism rate:
Fetal alcohol syndrome (FAS) often causes a distinct jawline characterized by micrognathia, or a small, underdeveloped lower jaw
Don’t know why it would show in males only, but could be you expect stronger jawlines on males and notice more their absence, while on females it is less expected and evident (also more makeup use to somewhat alter jawline appearance for women)
No, I definitely see a good jaw line more often in women than in men.
