The increasing number of crimes and its impact on society and the lives of individuals is undeniable and cannot be ignored. The importance of addressing this issue has long been of interest to many criminologists, sociologists, and lawyers. Accordingly, the purpose of this research was to examine the types of criminals from a criminological perspective. The approach of this research is descriptive-analytical in the form of content analysis and is applied in nature, and the method of conducting it is library-documentary. The results obtained in this study indicated that family status and circumstances, living environment, social class, occupational and economic status, age, and many other factors influence the type of criminal act committed by individuals. Accordingly, criminals are divided into different groups, such as white-collar criminals who were from the upper classes of society and with suitable economic and occupational conditions, who resorted to committing crimes. One of the reasons for the establishment of the black figure of crime is the crimes committed by this group of individuals. In contrast, we can discuss the type of crimes related to the working class, which usually occur among people from the lower classes of society and with unfavorable occupational and economic conditions, and are also referred to as blue-collar crimes.
