Analysis of the relations between the occurrence of crime and its spatial tendency in Shibuya area, Tokyo

摘要

Recently, as a measure against growing number of various crimes, crime prevention townrnplanning and the plan of criminal estimate system have attracted much more attention, which createsrnneed to research the relations between occurrence of crime and geographical and spatial characteristicsrnof the locations. Several researches revealed that such measures are effective in reducing criminal rate inrnthe Western developed countries. On the other hand, research in this field in Japan is behind considerablyrncompared with the West. This is because it is hard to get data relevant to a crime and few researchesrnbased on real data have been accumulated. Then, as a step to the future planning of crime preventionrntown and development of crime estimate system in Japan, it is necessary to reexamine “dangerous spacerntheory” suggested by many research es and reports not based on quantitative and systematic analysis ofrnreal data. Thus, in this paper, we focused on three kinds of crime, “Household burglary”, “Office burglary”rnand “Bag-snatching”, that seem to have distinctive characteristics in distribution in space and time and tryrnto examine example relations of space and crime taken from various studies and literatures using actualrnoccurrence data of crimes and to systematically show what kinds of space is how dangerous.
