Doswin, As far as pogroms, I don’t see any reason to speculate that the antisemites targeted men over women.
I see you’re missing my point. Age gap alone doesn’t account for a gender disparity, it’s only a factor if there’s also an ongoing population increase. The higher mortality rate, caused by a multiplicity of factors including pogroms, and incurable illness (both which don’t necessarily distinguish between the genders), would all contribute to a lower rate of population increase, and, hence, a smaller or nonexistent gender disparity.
