I used to have several friends in Pakistan, a country with a relatively low average age. IIRC, Pakistan is the "youngest" country on the planet, demographically speaking, and has a lot of problems that grow out of that. So I have read up a bit on how average age interacts with things like crime rates, tendency to be involved in violent organizations, etc.
More adults/higher average age/demographic shift in one direction or the other has a known impact on group tendency towards either civility or violence. The most violent groups on the planet are predominantly made up of young men under a certain age. Governments take advantage of that reality for filling the ranks of their military branches.

Anyway, maybe I am just saying it badly.
Have a good day.
