The narrative is as what I have read from a book, wikipedia, and published articles from the 1960-1970s, where much of this theory also goes under first-wave, second-wave, third-wave, fourth-wave and post-feminism definitions. The history is not exactly defined in stone by any measure so it could be wrong.

When it comes to actually numbers I would like to think that most people would agree to view women and men as androgynous humans for all practical purposes unless it involves the sliver of domains where sex difference actually can be proven to have a large impact, and then being skeptical since most such finding that I have read get later reversed and attributed to culture and bias. I will assume you are one of those and thus give you an up vote.
