The other women who were lucky enough to avoid being forced into prostitution (to service the broad masses of men) usually lived on farms in rural isolation and did a lot of manual labor.
This was a consequence of a male/female ratio imbalance caused by a high maternal death rate. It was common back in the good old days for women to die earlier than men ~ in greater numbers simply from the consequences of childbirth.
Having an adult man/woman ratio of 1/1 is a modern novelty that's had a run of just over a century, and only in the modern industrialized nations.
It's totally abnormal.
Do you have a cite to back that up?
My understanding is that while many young women died in childbirth, many young men died in battle or in dangerous occupations so it evened out.
To somewhat counterbalance the high female death rate in childbirth, there was also a very high male death rate in accidents (no OSHA back then) and war. Most "indigenous" or "traditional" societies were pretty much constantly at war. While major battles with lots of dead guys killed all at the same time were usually rare, it was not at all uncommon for the constant killing in raids and ambushes to add up to a 20% to 50% death rate for men.
In addition, homicide, mostly of men by men, was MUCH higher in most traditional societies, as in 5x to 20x that of the US today.
From what I've been able to find out, most societies did not have a large preponderance of males over females.
You forgot to account for the fact that men are also more likely to die on a battlefield than women, which I think will offset the women dying in childbirth. And although more boys by pure biology are conceived than girls, more boys than girls suffer mishap before birth through a defect. [i.e. that longer extra X chromosome gives the girls a backup gene that boys don’t have.] So when babies are actually born, the ratio is closer to 1/1.
