Wow, this seems like our society needs to control this ratio in the future!
We can have more peaceful society if we reduce "men count" to keep ratio above 1:1.1 (male:female) :-)
This is done “accidentally” with major conflicts in history. Post WWII Soviet, for example. Lots more men than women got killed during the war and the post war male:female ratio is (from memory) around 1:1.15
