California Counties
In 1930, the FBI assumed responsibility for managing the Uniform Crime Reporting (UCR) program, collecting data from 400 cities.  By 2006, over 15,000 law enforcement agencies submitted crime reports to the FBI, but since not all jurisdictions provide reports there is a possibility that you won't find complete data on some of our agency crime report pages.  In every case where the FBI has assigned a population to a jurisdiction, we are providing a page even though it may be blank. When a city located in a county starts submitting its own reports, the population assigned to the county is reduced to reflect that fact.

The UCR can be presented here because of the hard work of law enforcement statisticians who must classify and score each crime according to the strict criteria developed for the UCR.   Some agency's crime reports do not have a population associated with them, these may include: the highway patrol, state police, a drug enforcement agency, an environmental enforcement agency, a transportation utility, colleges, and others.  Areas may have many agencies performing the same or different law enforcement functions, and a population can only be assigned once, so it is not possible to formulate a crime rate for every agency.

Knowing the trend of the rate of crime can be an important measure of the social health of our communities.  An unusually high rate may be caused by an isolated tragic event, the location of the jurisdiction in an area with a large industrial zone or that serves as a tourist destination, and a low rate may be caused by the assignment of crimes to multiple agencies serving the same area, only one of which can be assigned the population, or an error in the number of crimes reported.

The UCR does not include a record of every crime reported to law enforcement, and every agency does not submit data in the form that the FBI requests.  The most accurate number of crimes reported are those involving death.  The least accurate is the number of rapes that are reported. The the number of case of rape reported does not include attempted rapes.  Aggravated Assault does not include cases of simple assault, (which are the largest number of assaults reported to police) and so constitutes only a portion of the total number of reported assaults.  The number of Aggravated Assaults used here was arrived at by subtracting the number of Simple Assaults from the Total Assaults reported by each agency.  For a few agencies, this process resulted in the generation of a negative number (their UCR report wrongly indicates that there were more simple assaults than the total number of reported assaults).

The magnitude of a threat/risk is measured by its frequency and effect. By this definition crime may well constitute the single greatest risk/threat we face today.   If you have questions, comments, or suggestions, please see our FAQ page first at: http://www.disastercenter.com/UCR.html and feel free to post a message to host@disastercenter.com.  
 

National Criminal Victimization Survey, 1996 estimate that only  37% of rapes are reported to police
