Përmbledhja	Displacement and diffusion analysis evaluates what happens around a crime-prevention intervention: does crime simply move to nearby areas, times, or targets (displacement), or do the benefits spill over so that crime also falls in surrounding untreated areas (diffusion of benefits)? Bowers and Johnson's weighted displacement quotient (WDQ) provides a simple, widely used metric that compares pre/post crime change in a target area, a surrounding buffer, and a control area.	Crime mapping is the practice of geocoding crime incidents to their locations and using geographic information systems (GIS) to visualize and analyze where crime concentrates. It spans simple pin maps, area-based choropleth maps, and continuous density surfaces, and underpins the geographic side of modern crime analysis — from CompStat briefings to problem-oriented policing.
