Interpreting the Violent Crime Maps

Violent crime rates are measured per resident, so places packed with visitors after dark read high even when few people live there. Bars, clubs, event venues, and transit hubs draw the crowds where assaults and robberies cluster. How strongly this shows on the map depends on the commercial base; the central part of the neighborhood has more retail establishments. A red block full of bars and venues does not mean the homes around it are dangerous.

Transit stations show the same effect: large moving crowds, few residents, so per-capita violent crime reads high. Before judging a residential street, weigh both the per-capita rate and the total count of incidents, and note what draws crowds nearby.
