To tell apart the impression of inexperienced areas from the social components usually related to crime – inhabitants density, earnings, training, range and social drawback – we took these components under consideration when evaluating the info on the crime.

Property crime was 38% to 63% larger in areas close to parks.
The one exception was Phoenix, the place the close by parks had no impression on property crime.
