The increase in violent crime was the result of an upward swing in assaults, which rose 22 percent, from 4 million in 2010 to 5 million last year. But the incidence of rape, sexual assault, and robbery remained largely unchanged, as did serious violent crime involving weapons or injury.

Property crime was up in 2011 for the first time in a decade, from 15.4 million in 2010 to 17 million.
