摘要：RECESSIONS, DRUGS, AND IMPACTS ON PROPERTY CRIME IN CALGARY The average number of break & enter and vehicle theft incidents in Calgary has increased by more than 50% since early 2015. The graph reports monthly data on incidents of what we refer to as property crime in the City of Calgary – break and enter and vehicle theft – and its spread over time. The horizontal red lines identify the average number of incidents in each month during two periods: January 2012 to December 2014 and January 2015 to March 2018. The data show a clear jump in the number of property crime incidents beginning in early 2015. Such a sudden and large increase in property crime suggests an equivalently sudden and large change in one or more causal factors, which would explain the increase in property crime incidents. The following two explanations are plausible.
