Coburn ABSTRACT The literature on the urban analysis of homicide occurrence has been dominated by American research largely patterned upon methodology developed by Wolfgang (1958). Subsequent homicide theory development and hypothesis testing, were largley founded upon American experience with American generated data. The current thesis arose with a query whether empirical generalizations and theory development of urban homicide patterns that have developed in the United States could be readily transferred to the Canadian experience. The purpose of this thesis is to fill a void in the literature by the introduction of primary Canadian homicide data from the obse~ed patterns of homicide in Vancouver, British Columbia. All homicides that occurred in the City of Vancouver between January 1, 1980 and December 3 1,1986, formed the sample. Data for the 204 victims and 174 suspects of homicide who were identified in 194 homicide cases, were gathered from the complete homicide file as prepared by the detectives of the Major Crime Section of the Vancouver City Police. Methodology developed by Wolfgang (1958) was employed to examine patterns of homicide with respect to twenty-four victim, suspect, and situational variables. In addition, the spatial distribution of homicide was examined employing techniques developed by Bullock (1955) and Wilt (1974). The major findings of this study revealed both similarities and profound differences in the patterns of homicide in Vancouver and that of the literature. Although the absence of a large black population in Vancouver precluded direct comparisons regarding racial involvement, it was discovered that Native iii Indians in Vancouver had numerical involvement with homicide occurrence that was far in excess of their proportion in the population. It was also found that firearms were rarely used in Vancouver homicide, in contrast to American and national Canadian statistics. The importance of alcohol as a factor in urban homicide was further exemplified by the analysis of the exact levels of blood alcohol content of the participants of homicide in Vancouver. Two "strategic areas" and a "strategic spot" of homicide in Vancouver were identified. It was suggested that the high homicide rates found in the strategic areas, may have resulted from the violent interaction of a number of subcultures found within the areas. The interaction and "convergence" of the various subcultures is speculated to be largely responsible for the fact that Vancouver, for the last ten years, has had the highest per capita homicide rate of any large urban centre in Canada. In conclusion, recommendations were made to improve the current methods of data collection, and the reporting of homicides, by the police, to Statistics Canada.
