The elevated risk for violence against cohabiting women: a comparison of three nationally representative surveys of Canada.

This study examined cohabiting women's elevated risk for male partner violence. It was predicted that an increased rate of cohabitation would be accompanied by a reduction in the bias toward selection into cohabitation and that this would result in greater similarity between characteristics of cohabiting and marital relationships as well as in their respective rates of violence. The results were generally consistent with this prediction. Cohabitation increased in Canada between 1993 and 2004, which appeared to have been reflected in some reduction in differences in selection and relationship variables as well as in lower rates of violence for cohabiting relative to married women. Nevertheless, persons who cohabited remained a select group and several relationship differences persisted. These selection and relationship differences accounted for the persistence of cohabiting women's elevated odds of violence in each survey. Results suggested that rates of violence in cohabiting and marital unions should eventually converge.
