Any record of crimes such as "offenses known to the police," arrests, convictions or commitments to prison can be considered at most crime index, or an estimate of crimes committed.
Explanation:
There are several approaches used to assess violence. Sporadically, public surveys are performed to determine the magnitude of the crime not reported to police. These surveys are typically more accurate for pattern assessment. A crime rate is determined by dividing the total population from the number of reported crimes, the outcome is multiplied by 100,000. In 2012, for instance, California had 58,100 robberies and the population was 38,826,898. This represents a 149.6 rate of robbery crime per 100,000 general public.
