The research on domestic violence, referred to more precisely in academic literature as “intimate partner violence” (IPV), has grown substantially over the past few decades. Although knowledge of the problem and its scope have deepened, the issue remains a major health and social problem afflicting women. In November 2014 the World Health Organization estimated that 35% of all women have experienced either intimate partner violence or sexual violence by a non-partner during their lifetimes. This figure is supported by the findings of a 2013 peer-reviewed metastudy — the most rigorous form of research analysis — published in the leading academic journal Science. That metastudy found that “in 2010, 30.0% [95% confidence interval (CI) 27.8 to 32.2%] of women aged 15 and over have experienced, during their lifetime, physical and/or sexual intimate partner violence.” The prevalence found among high-income regions in North America was 21.3%. Of course, under-reporting remains a substantial problem in this research area. - See more at: http://journalistsresource.org/studies/society/gender-society/domestic-violence-abusive-relationships-research-review#sthash.EWPJ23Xl.dpuf
