Description

In recent years, the overall trends in crime in the District have been down. Yet, news accounts often report surges in crime. Monthly burglary, robbery, and homicide are volatile and can go up even during a long-term downward trend. Does an increase in crime in a given month—compared with last month or last year—suggest that crime is on the increase? The key to reconciling short-term changes in crime with longer-term trends is to understand the volatility of crime. In this brief, we explore this issue by examining monthly changes in crime during the past decade against the background of longer trends.
