Characteristics of the urban environment influence where and when crime events occur, however past studies often analyze cross-sectional data for one spatial scale and do not account for the processes and policies that influence crime across multiple scales. This research applies a Bayesian cross-classified multilevel modelling approach to examine the spatiotemporal patterning of violent crime in the Region of Waterloo, Ontario, Canada. Violent crime is measured at the small-area scale and small-areas are nested in three higher-level areas that have overlapping boundaries: neighborhoods, electoral wards, and patrol zones. Violent crime is found to be positively associated with population size, residential instability, the central business district, and commercial, government-institutional, and recreational land uses within small-areas Violent crime is also shown to be negatively associated with civic engagement within electoral wards. Combined, the three higher-level units explain approximately fifteen percent of the total spatiotemporal variation of violent crime. This research advances understanding of the multiscale processes influencing spatiotemporal crime patterns and provides area-specific information for policy-makers in urban planning, local government, and law enforcement.
