Thesis: Rates of Domestic Violence are approximately equal between men and women, and studies showing this are suppressed for political reasons. While female victims may suffer more physical harm, female aggressors are less likely to be convicted.

Rates approximately equal:

ABSTRACT A review is made of female intimate abuse. It is concluded that females are as abusive as males in intimate relationships according to survey and epidemiological studies. This is especially so for younger “cohort” community samples followed longitudinally. Predictors of intimate violence with women appear to be similar to those of men; including antisocial criminal records, alcohol abuse, and personality disorders.

SUMMARY: This bibliography examines 286 scholarly investigations: 221 empirical studies and 65 reviews and/or analyses, which demonstrate that women are as physically aggressive, or more aggressive, than men in their relationships with their spouses or male partners. The aggregate sample size in the reviewed studies exceeds 371,600.

Results. Almost 24% of all relationships had some violence, and half (49.7%) of those were reciprocally violent. In nonreciprocally violent relationships, women were the perpetrators in more than 70% of the cases. Reciprocity was associated with more frequent violence among women (adjusted odds ratio [AOR]=2.3; 95% confidence interval [CI]=1.9, 2.8), but not men (AOR=1.26; 95% CI=0.9, 1.7). Regarding injury, men were more likely to inflict injury than were women (AOR=1.3; 95% CI=1.1, 1.5), and reciprocal intimate partner violence was associated with greater injury than was nonreciprocal intimate partner violence regardless of the gender of the perpetrator (AOR=4.4; 95% CI=3.6, 5.5).

Supression:

Processes Explaining the Concealment and Distortion of Evidence on Gender Symmetry in Partner Violence:

Graham-Kevan's paper raises the question of how an explanatory theory and treatment modality could have persisted for 30 years and still persists, despite hundreds of studies which provide evidence that PV has many causes, not just male-dominance. The answer is that it emerged from a convergence of a number of different historical and social factors. One of these is that gender symmetry in perpetration of partner violence is inconsistent with male predominance in almost all other crimes, especially violent crimes. Another is the greater injury rate suffered by female victims of PV brings female victimization to public attention much more often. Although there are many causes of the persistence of the patriarchal dominance focus, I believe that the predominant cause has been the efforts of feminists to conceal, deny, and distort the evidence. http://pubpages.unh.edu/~mas2/V74-gender-symmetry-with-gramham-Kevan-Method%208-.pdf

Male DV aggressors more likely to kill their partners, but female aggressors less likely to be convicted:

"Wife defendants less likely to be convicted Wife defendants had a lower conviction rate than husband defendants-- Of the 222 wife defendants, 70% were convicted of killing their mate. By contrast, of the 318 husband defendants, 87% were convicted of spouse murder. Of the 100 wife defendants tried by either a judge or jury, 31% were acquitted. But of the 138 husband defendants tried, 6% were acquitted. Of the 59 wife defendants tried by a jury, 27% were acquitted. But of the estimated 91 husband defendants tried by a jury, none was acquitted.
