“Crime Finds the Never Married” is the conclusion drawn in an article from USA Today (June 29, 2001). This conclusion is based on data from the Justice Department’s National Crime Victimization Survey, which estimated the number of violent crimes per 1000 people, 12 years of age or older, to be 51 for the never married, 42 for the divorced or separated, 13 for married individuals, and 8 for the widowed. Does being single cause an increased risk of violent crime? Describe a potential confounding variable that illustrates why it is unreasonable to conclude that a change in marital status causes a change in crime risk.
