Using the Problem-analysis Triangle (PAT)

It is possible to get a clearer understanding of the community safety priorities within your area by considering the different aspects of the crimes that are occurring. Introduced through Routine Activity Theory (one of the main theories of environmental criminology), the problem-analysis triangle (PAT), is a useful way to think about a problem, as well as guiding the response. Routine Activity Theory suggests that in order for a crime to happen, three things need to be present at the same time and in the same space:

  • A suitable target (either human or object).
  • Lack of a suitable guardian to stop the crime from happening.
  • A likely and motivated offender.

As presented below, the inner triangle (victim/offender/location) provides a helpful way to think about the problem (or suitable target), while the outer triangle (handler/guardian/manager) helps to guide the appropriate response.
