eli5: How does the population ratio between women and men keep so equal? (A Different Approach)

Question

Hey! I’m wonderin that how does the population ratio is still more or less %50-50 (%49.5 female vs %50.5 male) even that the knowledge we know;

1- Men is being killed, and killed in past in wars.

2- Men is working on heavy-duty jobs that killed men.

3- We also know that the expected life span of a female is higher than men.

​

So, there should be some imbalances, right?

Men dies in wars, in dangeroues jobs and has less life time.

​

So, how does the ratio keep its balance?

Answer 1

We don’t often die during child birth, or as a complication of such.
We also have a culture that for some reason values Male heirs that much higher than females, that in counties with population control measures in place, it was common place for females to be aborted, and or abandoned (China for example).
And whilst males are at a significantly higher risk of being the victim of violent crime, comparable to females, due to some of our innate physiological differences, were also less likely to incur as much physical damage as say, a biological sex known for less muscle mass, bone density ect when experiencing the exact same level the of violence.

Also, female life expectancy is higher than males, as it takes into account your first and second point too.

Additionally, whilst many men are killed during wars, many women are killed as the spoils of war

However, another point is, that throughout history, there have been times it hasn’t been so equal – after crisis like world wars. Women typically outnumbered men, and this along with other circumstances was leveraged most during sufferegette movements, empowering women to a more equal footing, with rights like the ability to vote.

So to answer your question, why does the ratio remain so equal?
One, it doesn’t, it just takes a big shift to swing the ratio,
two the stats you’re looking at are bias towards men (what I mean is you’re looking at areas men die more than women, without considering that it could be balanced, by the areas women die where men don’t)
and three, as a species we’ve placed more importance on culture, social conventions, and our ability to deny/alter/meddle with nature than to live within its confines and allow it to truly rule us.
