Research / Themes / Space and place / Near repeat phenomenon

The near repeat phenomenon states that if a location is the target of a crime (such as burglary), nearby locations within the immediate vicinity have an increased chance of being burgled for a limited period of time. This communicability of risk to nearby places for a short amount of time raises the possibility that other crime types may also suffer from a near repeat spatio-temporal pattern of behavior. Working collaboratively with the UK team that first identified the near repeat phenomenon and with Dutch researchers from the Netherlands Institute for the Study of Crime and Law Enforcement, Temple faculty have been at the forefront of developing and expanding the significance of this recent and important spatiotemporal crime pattern discovery.
