The National Crime Victimization Survey (NCVS) reports violent and property crime rates in 2008 were at or near their lowest levels in over three decades. Violent crimes are categorized as rape, sexual assault, robbery, aggravated assault, and simple assault. "Property crimes include household burglary, motor vehicle theft, and theft." Personal theft, including pocket picking and purse snatching are also included. The data is in concurrence with the Federal Bureau of Investigation's (FBI) Uniform Crime Reports (UCR) which also notes the continual downward trend in criminal activities over the same time period.
