This indicator is calculated by dividing the number of total reported incidences of serious crimes by the population. We multiply the result by 10,000. Total or serious crimes include violent crimes (murders and non-negligent manslaughter, rape, robbery, and aggravated assault) and non-violent crimes (burglary, larceny-theft, and motor vehicle theft). In counties with relatively few people, a small change in the number of serious crimes reported may have a significant effect on rates from year to year.

Limitation of the Data: The FBI's Uniform Crime Report (UCR) is a voluntary program, whereby participating law enforcement agencies report incidents of seven selected serious crimes. Local agencies may classify reported crimes differently, causing comparability problems at the community level.
