The study of crime and place recognizes the important interplay between the physical landscape and criminal activity. In doing so, research in this area has shown substantial concentrations of crime amongst micro geographic units, such as street blocks. Despite these revelations, little research has examined whether such criminal concentrations persist over time. The developmental trajectory of criminal activity on street blocks was originally studied in Seattle, Washington. This dissertation replicates that seminal study by examining crime volumes on the streets of Vancouver, British Columbia, over a 16 year period using a group-based trajectory model (GBTM). Going further, this research also applies a non-parametric technique, termed k-means to address various limitations inherent to the GBTM method. The major findings reveal the majority of street blocks in
