ABSTRACT
Study the problem by putting data in a graph of either the number of events or a rate plotted against time. A rate is typically the number of crime or disorder events divided by the number of targets at risk (Step 25). If both the number and the rate are plotted, and they have the same shape, then change in the number of available targets does not play an important role in changing the problem. If the two graphs look different, then targets are an important consideration.
