The CDC conducts an annual intimate partner violence survey. The survey asks both men and women about their experiences with intimate partner violence and the last survey is available here:
Important findings include:
Severe physical violence by an intimate partner (including such acts as being hit by something hard, being kicked or beaten or being burned on purpose were experienced by 2.3 % of women and 2.1% of men during the 12 months prior to the survey.
9.8% of women and 4.8% of men have missed at least one day of work or school due to intimate partner violence
Roughly two thirds of men but only half of all women who indicated a need for medical, legal, or housing services due to intimate partner violence received those services
Contrast the CDC's evidence of the problem of domestic violence by women with the standard narrative that female perpetrators are rare. For instance the Georgia Commission on Family Violence issues an annual fatality report. In their 2011 report available here:
They described domestic violence perpetrated by women as a "statistical rarity" and suggested "helpful categories or ways in which women's use of violence can be defined: immediate self-defense; delayed self-defense; retaliatory violence; hyper-vigilant violence; and anticipatory, preemptive violence".
These "helpful" categories appear to be mechanisms to insure that violence by women never be labeled as domestic violence.
While the Georgia Commission gives a list of excuses for female perpetrated violence, the agency says that they believe that perpetrators should be held accountable.
Perhaps most telling of all, they never suggest that a man's use of violence could just as easily be interpreted using the same "helpful categories or ways".
