Figure 7. Sensitivity of Reduction in Offenses to Agent Density.

Models were created with 110% and 90% of the adult agents in the baseline model, and each modified model was run for 50 replications for each intervention type and for each level of intensity. For all models, spatially focused interventions reduce offenses slightly more than community-wide intervention if fewer than about 2% of adults are activated, but community-wide interventions provide a larger reduction in offenses for intervention that activate more than 3% of the adults in the community. The general performance of both intervention strategies was consistent across the tested variations in the agent density.
