According to a 2003 United Nations report, across the world, at least one out of every three women has been beaten, coerced into sex, or otherwise abused in her lifetime, with most of the abuse inflicted by a woman’s current or former partner. However, currently more than 45 countries have developed specific legislation on “domestic violence.” In the past decade, researchers have found a decline in the rates of violence in North American society, and most importantly for this special issue on violence against women by intimate partners, in the rates of both lethal and nonlethal forms of intimate partner violence. This issue was initiated so that practitioners, scholars, and policymakers might have the opportunity to examine more carefully where the accumulation of knowledge about intimate partner violence is today, specifically for Canada, the United States, and the United Kingdom. Through the five articles in this issue, the intent is to identify which parts of the world need the greatest attention. The articles search for and propose new knowledge as well as explore both theoretical refinement and methodological insights. They are important contributions to existing knowledge and important tools in identifying paths that need further exploration in the continuing battle to eradicate lethal and nonlethal violence against female intimate partners.
