According to Centers for Disease Control and Prevention, mariticide made up 30% of the total spouse murders in the United States, data not including proxy murders conducted on behalf of the wife.[1] FBI data from the mid-1970s to mid-1980s found that for every 100 husbands who killed their wives in the United States, about 75 women killed their husbands indicating a 3:4 ratio of mariticide to uxoricide.[2]
