Valley: Violent crimes reported Note: Number of reported incidences of violent crimes (murders and non-negligent manslaughter, rape, robbery, and aggravated assault) per 10,000 population. 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. This is especially true for violent crime in smaller communities, where the small number of offenses may have a significant effect on crime rates from year to year. 2001 estimates of total population have been updated per the Census Bureau's updates. NA = not available. For 2021 and on, state level data has changed in its reporting so those data are no longer reported on this site. See (https://cde.ucr.cjis.gov/LATEST/webapp/#/pages/explorer/crime/crime-trend) for state level data. For more detailed notes, please visit the data sources.
