The new police-reported Crime Severity Index (PRCSI) was introduced in 2009 to enable Canadians to track changes in the severity of police-reported crime from year to year (Wallace 2009). The weighted clearance rate is based on the same principles as the PRCSI, whereby more serious offences are assigned a higher “weight” than less serious offences. For example, the clearing of homicides, robberies or break and enters would represent a greater contribution to the overall weighted clearance rate value than the clearing of minor theft, mischief or disturbing the peace.

Dollars of a particular base year, which are adjusted (by inflation or deflation) to show changes in the purchasing power of the dollar. The Consumer Price Index was used to calculate constant dollars over a base year of 2008 (2008=100).
