     modern research on criminal phenomena has been revolving not only around preventing existing offenses, but also around analyzing the criminal phenomena as a whole so as to overcome potential happenings of similar incidents. criminologists and international law enforcement have been attracted to the cause of examining demographic context on which a crime is likely to arise. traditionally, little has been explored in using demographic variables as determinants of the aggregate level of crime in the crime literature. rapid development and ubiquitous application of information technology enables academic field to perform crime analysis using visualization techniques. automation and networking make it available to access massive amounts of crime data, typically in the form of crime statistics. in numerous fields, studies and research have shown that visualization techniques are valuable; in crime research, nevertheless, there is a general lack of its application. in order to efficiently and effectively process crime data, criminologists and law enforcement are in demand of a more powerful tool. the self-organizing map (som), one of the widely used neural network algorithms, may be an appropriate technique for this application. the purpose of this study is to apply the som to mapping countries with different situations of crime. a total of 56 countries and 28 variables are included in the study. we found that some roughly definite patterns of crime situation can be identified in traditionally homogeneous countries. in different countries, positive correlation on crime in some countries may have negative correlation in other countries. overall, correlation of some factors on crime can still be concluded in most groups. results of the study prove that the som can be a new tool for mapping criminal phenomena through processing of large amounts of crime data.
