I have seen a statistic pop-up that most domestic violence is mutual. The figure is then shown that women are higher perpetrators of non-reciprocal violence. You can find a figure like this here. (https://ajph.aphapublications.org/doi/abs/10.2105/AJPH.2005.079020?role=tab)

I have also seen various research that show men and women to suffer roughly equally from domestic violence although women seem to suffer more from sexual violence. Sometimes the stats might point to men suffering from domestic violence less and sometimes more.

My question is this, if women are higher perpetrators of domestic violence and most relationships are heterosexual, shouldn't men be appearing as the gender who suffers domestic violence by some proportion more?

Perhaps it is just a flaw of the study I linked. It only looks at a subset of the population. Perhaps women are more violent when non-reciprocally younger and men more non-reciprocally violent when older and it kind of balances out. Has anyone noticed this issue? I am not trained in stats and feel I might be missing something.

(My personal perspective is that I expect domestic violence rates to be about equal from my perspective on humanity and the research I have found. I do expect certain types of domestic violence to imbalanced though.)
