Crime data that is collected and reported by participating agencies provides an overview of criminal activity, but does not provide data on all crimes committed in a particular jurisdiction.  For the purposes of this indicator, property crime and violent crime totals only include what is reported under Washington Uniform Crime Reporting Program (WUCR) as Part I offenses which include, for violent crimes: murder and non-negligent manslaughter, forcible rape, robbery, and aggravated assault; property crimes considered Part I offenses include: burglary, larceny-theft, motor vehicle theft, and arson. 

Violent offenses are counted per each victim, while property crimes are counted for each distinct operation, and motor vehicle theft is counted per vehicle stolen.  Attempts to commit crimes are counted as actual offenses except for attempts to kill and assaults to kill which are counted as aggravated assault.

Property Crimes during the reporting period 2000 to 2010 were at a high point of over 42,000 offenses in 2000.  In 2010, property crimes fell approximately 8% from the year before to 31,695 offenses and have fallen 25% overall since 2000.
