According to a U. S. Bureau of Justice Statistics (BJS) study, one measure of the number of children living in households that experienced violent crime declined from 1993 to 2010.
Using data from the BJS National Crime Victimization Survey, researchers looked at the number of children age 17 or younger who live in households where someone age 12 or older was the victim of a violent crime. In 2010, about 2.8 million children or 3.9% of all children age 17 or younger lived in such households. In 1993, an estimated 8.7 million children, or 12.6%, did so. The researchers found that this corresponds with the decline in overall violent victimizations during this period.
