This brief describes the theory and evidence of a form of social control known as place management. Created by property owners, place management is an alternative to the two other domains of social control: formally created by the state and informally created by residents. It helps explain the high concentration of crime and disorder at a relatively small proportion of addresses and facilities. This volume examines the specifics of place management and extends it in three ways: to show how high crime places may radiate crime into their surroundings; to reveal networks of places that create crime hotspot spanning blocks; to demonstrate how networks of place managers influence crime throughout neighborhoods. Finally, it shows that the policy implications of place management extend far beyond the police and should include regulatory policies.
