Key research themes
1. How consistent is the spatial concentration of crime across cities and crime types, and what mechanisms explain this concentration?
This research area focuses on measuring the degree to which crime concentrates in small geographic units (e.g., addresses, street segments) across different cities, crime types, and time periods. Understanding whether consistent patterns or 'laws' of crime concentration exist helps criminologists identify stable micro-locations driving broader crime trends. The area also investigates the underlying mechanisms behind these concentrations, such as repeat victimization, offender behavior, and characteristics of 'risky facilities.'
2. How do urban spatial configuration and physical environmental factors influence crime occurrence and fear of crime in public spaces?
This theme investigates the role of physical urban form, spatial configuration, city morphology, and the built environment in shaping crime patterns and perceptions of safety or insecurity. It spans micro- to macro-scale analyses, incorporating concepts of Crime Prevention Through Environmental Design (CPTED), social cohesion, defensible space, and urban morphology to understand how spatial context and design affect both actual crime and the public's fear of crime, which impacts urban policy and planning.
3. What are the methodological advancements and challenges in measuring and analyzing spatial and temporal patterns of crime and perceptions of safety?
This research area evaluates advances in empirical and statistical methods to quantify crime concentration, hot spot persistence, and fear of crime as a dynamic experience. It considers traditional and novel indices (e.g., Gini, Simpson, Shannon, Decile), spatial-temporal analytical techniques, and innovative data collection methods (e.g., mobile experience sampling). These methodological contributions aim to enable more precise mapping, understanding, and intervention in crime phenomena and perceptions at relevant spatial and temporal scales.
