    Historically, before agriculture it was about two to three women having offspring for every man who did.

    During the Agricultural era (12,000 BCE to 2,000 BCE) that ratio hit a high of 9 women reproducing for every man who did so, and stayed around that for most of that time.

    From there it slowly declined back down to the current world-wide average of two women reproducing for every man who manages to do so.
