Studies have consistently found that safety and security are major public concerns; however, crime is rarely considered as an outcome in public health. The recent shift by planning policy towards promoting compact, ‘walkable’ communities close to public transport aims to redress many of the problems associated with urban sprawl. However, communities that do not feel safe are less likely to be active citizens. This paper argues that Crime Prevention Through Environmental Design has potential benefits for public health in the provision of local crime risk assessments and in delivering safer environments, which can support active living, walkable communities and public health.
